Astronomers made two observations of the Moon that were several days apart. Their observations are shown in the diagram above. The light part of the Moon appeared to get larger over time. Why did this happen?
A.
Between the first observation and the second observation, the Moon rotated so that more of the light-colored rock on the Moon’s surface faced Earth.
B.
Between the first observation and the second observation, the Moon moved so that the astronomers were able to see more of the half that faces the sun.
C.
Between the first observation and the second observation, the Moon moved closer to the sun so more sunlight reached the Moon’s surface.
D.
Between the first observation and the second observation, Earth moved so its shadow was blocking less of the Moon so the astronomers were able to see more of it.

In humans, both cystic fibrosis and the inability to taste phenylthiourea are inherited as autosomal recessive traits. Two parents without cystic fibrosis and without the ability to taste phenylthiourea have a daughter who can taste phenylthiourea and has the cystic fibrosis condition. What is the probability that their next two children will both be born without cystic fibrosis and both have the ability to taste phenylthiourea?
Answers
The likelihood of producing two kids that can taste phenylthiourea and don't have cystic fibrosis is (1/16) * (1/16) = 1/256.
What is cystic fibrosis?The lungs, digestive system, and other body organs are severely harmed by cystic fibrosis (CF), a genetic condition.
The cells that make mucus, perspiration, and digestive fluids are impacted by cystic fibrosis. Normally, these produced fluids are slick and thin.
We need to take into account the likelihood of getting the AA combination in both genes in order to determine the likelihood of having a child without cystic fibrosis and with the capacity to taste phenylthiourea.
For each gene, the likelihood of this occuring is (1/2) * (1/2), which results in a probability for both genes of (1/4) * (1/4) = 1/16.
Therefore, the likelihood of producing two kids that can taste phenylthiourea and don't have cystic fibrosis is (1/16) * (1/16) = 1/256.

Which of the following statements about fossil evidence from plants is true (select all that apply): Question 2 options: Sporophytes were branched before the evolution of vascular tissues. In early land plants the gametophytes were branched and complex like the sporophytes. The earliest known fossil beds, the Rhynie Chert, dates to 360 mya. Since fossilized remains are often rock-like, it is only possible to observe large characteristics, not cellular ones.
Answers
Answer:
Sporophytes were branched before the evolution of vascular tissues
In early land plants the gametophytes were branched and complex like the sporophytes
Explanation:
The fossil record shows that early land plants appeared in the Ordovician Period, approximately 470 million years ago (Mya). These plants were non-vascular plants (e.g., mosses and liverworts) which can be recognized as fossilized spores. Thus, the first land plants could not transport nutrients like sugar, water, or minerals around the plant. Nowadays, it is believed that early land plants had gametophyte dominant life cycles (haploid life phase), while vascular tissues evolved as an adaptation to life on land, in the sporophyte (diploid life phase).

B. lions, rhinoceros, giraffes, and elephants
C. deer, fruit-eating birds, lizards, and snakes
D. migratory animals, oxen, caribou, and artic foxes
Answers
Answer: D (migratory animals, oxen, caribou, and arctic foxes)
Explanation: Migratory animals stay in the tundra during the "summer" months but leave during the colder and harsher months. The oxen and caribou have lower surface area to volume ratio which makes less heat able to dissipate into the surrounding area. They also have thick coats. In the summer fox are able to raise their young and prey on the birds and such that may migrate there.
The animals which live in the normal conditions live in this area. The correct statement is option D.
What is the most common animal in Tundra ?The most common animal in Tundra is the Arctic Fox.
Tundra wildlife usually contains the animals such as the The arctic foxes, migratory animals, oxen and caribou. There are harsh conditions in the winter thus the animals tend to elope from such areas in this case they are saved from the adverse effects of the weather and the climatic conditions.
The arctic fox is one of the most common animals that are found in the Tundra as the fox has thick skin with the property that it turns from brown to white in winter and the large body of them helps to preserve the heat that helps them to get saved from the adverse effects of temperature.

how would you define the following terms to a
child?
1. stereotype
2. racism
3. discrimination
4. conformity
Answers
1. A stereotype is a belief or an idea about a group of people that may not be true for everyone in that group. For example, someone might think that all girls like to play with dolls, but not all girls like dolls. Stereotypes can be hurtful because they can make people feel like they're being judged unfairly.
2. Racism is when someone treats someone else unfairly because of their race or skin color. It's wrong to judge people based on things like their skin color or where they come from because everyone deserves to be treated with kindness and respect.
3. Discrimination is when someone treats someone else unfairly because of things like race, gender, religion, or disability. Discrimination can take many forms, such as not hiring someone because of their race, or not letting someone play a game because of their disability. It's important to treat everyone with fairness and kindness, no matter who they are.
4. Conformity is when someone changes their behavior or beliefs to fit in with a group. For example, if everyone in a class is wearing a certain type of clothing, someone might feel like they need to wear the same thing in order to fit in. It's important to remember that everyone is unique and it's okay to be different. Being true to yourself is more important than fitting in with a group.
Racism: Racism is when someone is mean or unfair to another person because of the color of their skin, their background or where they come from. This is very wrong and hurtful to others, and we should always treat everyone with kindness and respect.
Discrimination: Discrimination is when someone treats another person unfairly because they belong to a certain group, such as their religion, race, gender, or age. Discrimination is wrong and hurtful to others, and we should always treat everyone equally and with respect.
Conformity: Conformity means following what other people do or think, even if you don't really agree with it. For example, if all of your friends like a certain TV show, but you don't really like it, you might still watch it because you want to fit in. It's important to be true to yourself and not just follow what everyone else does, even if it can be hard sometimes.
Density is mass per unit of volume. Which pair of lab instruments would a student use to measure the density of seawater?
A. a caliper and a flask
B. a stopwatch and a beaker
C. a balance and a beaker
D. a meter stick and a temperature probe
Answers
Explanation:
A balance would be used to measure the weight, which in turn effectively measures the mass (more or less). Imagine that we have a brick that we know is 1 pound. If we have an object that needs 5 bricks on one side to balance it out, then we know the object is 5 pounds.
The beaker is used to measure the volume. It's basically a measuring cup that you would find in the kitchen.
To get the density, you divide the mass over volume.
For example, if you have a material that has a mass of 100 grams and it's volume is 20 cm^3, then its density is 100/20 = 5 grams per cm^3.

ASAP- discovery of a series of fossils of human-like skulls, all slightly different from each other and from us, dating from throughout the past
4 million years indicates what process?
A. Punctuated equilibrium
B. Artificial selection
C. Gradualism
D. Disruptive selection
Answers
The discovery of a series of fossils of human-like skulls from throughout the past 4 million years indicates the process of Punctuated equilibrium. Thus, the correct option is A.
What is Punctuated equilibrium?Punctuated equilibrium may be defined as a type of speciation in which most of the time species are stable. But every now and then there is a disruptive event that promotes rapid change.
Gradualism may deal with the idea that evolution occurs at a slow but steady pace. Disruptive selection refers to environmental conditions that change in two different directions. Both of these processes do not make any sense here.
Therefore, the correct option for this question is A.

A scientist is researching two different traits in an insect: body texture and color. Smooth body (B) is dominant to bumpy body (b), and gray (G) is dominant to white (g). A BbGg and a bbgg insect mate and produce the following 480 offspring: Phenotype Number of Offspring Smooth, gray 119 Bumpy, white 117 Smooth, white 123 Bumpy, gray 121 What type of inheritance is displayed from these offspring
Answers
Answer:
Independent assortment
Explanation:
The type of inheritance displayed by the offspring is a simple independent assortment inheritance according to Mendelian law.
The result of crossing BbGg and bbgg is as follows (see the attached image)
4 BbGg smooth and gray
4 Bbgg smooth and white
4 bbGg bumpy and gray
4 bbgg bumpy and white
The phenotype ratio from the cross is 1:1:1:1 as far as the independent assortment is concerned.
Now, looking at the population of each phenotype from the cross
Smooth, gray 119
Smooth, white 123
Bumpy, gray 121
Bumpy, white 117
119:123:121:117 is approximately equal to 1:1:1:1.
Hence, the cross agrees with Mendel's law of independent assortment of genes.

Early genetic manipulation of petunias included an attempt to engineer dark purple petals. To this end, extra copies of the gene that causes purple pigment was engineered to be produced in the petunia. However, to the surprise of many, the plants carrying the extra copies of the purple gene were completely white or only had patches of color. Molecular analysis revealed that the purple gene was reduced 50-fold in the engineered plants compared to wild type. Provide a possible explanation how this occurred. Also, provide a possible experiment that may overcome this setback
Answers
Answer:
The altered pigmentation in transgenic petunia plants is caused by the RNA interference (RNAi) mechanism
Explanation:
The RNA interference mechanism is a naturally occurring mechanism by which single-stranded RNA molecules can bind to complementary mRNAs in order to inhibit gene expression, blocking translation and leading to mRNA degradation. The example above described is a classical genetic experiment (Napoli et al. 1990 ) that showed the existence of the RNAi pathway by the overexpression of a chimeric chalcone synthase (CHS) gene in pigmented petunia flowers, which blocked anthocyanin biosynthesis. In this experiment, irregularly bicolored/white flowers in transgenic petunias containing exogenous pigmentation genes were developed. The co‑suppression of gene expression was produced by the high-copy-number transcription of the CHS transgene, showing the existence of an undescribed RNAi silencing mechanism. Somatic reversion of the altered phenotype can be achieved by restoring the normal mRNA levels for these pigmentation genes, e.g., by a progeny testing in order to eliminate transgenic CHS expression.

A guinea pig with giant muscles is bred with a guinea pig with regular muscles. If muscle size in guinea pigs is INCOMPLETE dominance would these guinea pigs be able to produce a weak muscle guinea pig?
Answers
Answer:
Yes, they would be able to produce weak muscled guinea pigs
Please see details below
Explanation:
This question involves a single gene coding for muscle size in guinea pigs. The allele for giant muscles (G) is incompletely dominant over the allele for regular muscles (R). This means that a third intermediate phenotype (weak muscles) is produced in a heterozygous state.
According to this question, a guinea pig with giant muscles (GG) is bred with a guinea pig with regular muscles (RR). The following gametes will be produced by each parent:
GG - G and G
RR - R and R
Using these gametes in a punnet square (see attached image), the following proportions of offsprings will be produced:
GR, GR, GR, and GR
This shows that all the offsprings (100%) have weak muscles, hence, YES is the answer to this question.
