Which ones should she choose?

(a) Christina wants to increase the number of eggs per year by using selective breeding.(i)Which two

Answers

Simple is a good word to describe the fundamental approach. It is likely that her daughters will likewise be effective layers if you breed from the hen that produces the most eggs. This is so because a hen's genes, which she gets from her parents, play a factor in determining how many eggs she lays.

How did chickens raised for meat become a product of selective breeding?

Increased growth rate and higher meat output were the primary objectives of selective breeding in meat chickens in the 1960s (i.e. producing larger chickens in less time). These days, the strategy is much more balanced, with health and wellbeing of the breeding animals playing a key role.

Inbreeding, linebreeding, and outcrossing are methods used in animal breeding.

Alice was participating in a photosynthesis lab for science class.  The lab procedures instructed Alice to prepare a test tube containing water, a sprig of elodea (a common aquarium plant), and 10 g of sodium bicarbonate (NaHCO3). She was then instructed to place the test tube in front of a strong light source for one minute. Alice noticed tiny bubbles forming on the leaves of the elodea.   What is the most logical explanation for why Alice saw bubbles forming on the leaves of the elodea?Group of answer choicesThe bubbles formed as a result of the hydrogen from the sodium bicarbonate mixture dissolving the elodea leaves.The bubbles formed from the release of water molecules from the elodea leaves.The bubbles formed as the elodea plant released oxygen from the elodea leaves.The bubbles formed as the elodea plant released carbon dioxide from the elodea leaves.

Answers

Step 1.

Write down the experiment data.

- tube containing water;

- alodea (photosynthetic organism);

- 10 g of sodium bicarbonate;

- light source.

Step 2.

Why bubbles are formed on the leaves of the alodea?

The experiment have all the condictions for photosynthesis, since it provides: water (that is in the tube), CO2 (because of the dissolved sodium bicarbonate), light (because of the string light source). Therefore the most ogical explanation for Alice experiment results is: the bubbles formed as the elodea plant releases oxygen from the elodea leaves, that because with all the elements in the experiment the plant can do a normal photosynthetic process that way realing oxygen in the tube and forming bubbles of "air".

What principle underlies the notion of evolution?

Populations and species of organisms change through time; this is the fundamental tenet of biological evolution.

Genetic variations that are advantageous to an individual's survival are passed on through reproduction under natural selection. New organisms born as a result have a higher chance of surviving and reproducing.

Reproduction, heredity, variation in organism fitness, and diversity in individual traits among population members are the four prerequisites for natural selection to take place. Natural selection takes place automatically if they are met.

Variation, inheritance, selection, and time are the four principles that drive evolution. These are viewed as being part of the natural selection-based evolutionary system.

as the embryo begins gastrulation, the number of cells is between

Answers

Gastrulation is a process of transformation from a single layer of cells to a three-layered embryo. It marks the beginning of differentiation and regionalization of cells and the beginning of organogenesis.

 The process starts with a group of cells known as the blastula, which is composed of a single layer of cells in the shape of a hollow sphere. As gastrulation starts, the blastula cells combine to form an inner and an outer layer of cells called the ectodermal and the endodermal layers. In between these two layers a third layer of tissue, the mesoderm develops.

 The number of cells during gastrulation varies between species, and the exact number cannot be easily determined. However, the average is around 500-800 cells. The number of cells increases during the duration of the process, as more cells are generated and existing cells begin to divide and differentiate.

    Gastrulation is a fascinating and complex process that is essential for the formation of the embryo and the development of the body. The number of cells present during gastrulation is key to the successful formation of the organism, and understanding the number of cells can offer us insight into the development of the organism.

One day, at a certain time, a student measured the shadow of a fence and found that it was 2 m long. The next day, she measured the shadow of the same fence at a different time and found that it was 3 m. long. What can you infer about the time of day at which the student measured the shadows? Explain.​

Answers

Answer:

The time of day the second time the student measured the length of the fence shadow was either earlier or later than the first time she measured the shadow.

Explanation:

As the first time the student measured the shadow of the fence gave an answer of 2 meters, the second time gave an answer of 3 meters. For this reason, the shadow is longer in length. This means that the sun is closer to the horizon, yielding a light beam that is closer to the ground.

Moreover, if the sun was directly above the fence post, there would be no shadow. However, because the sun is closer to the horizon, showing that it is earlier or later then the first measurement, the second measurement has a longer shadow.

Answers

If you are confronted by a bear in the woods, your emotional arousal would be accompanied by constriction of pupils to increase visual acuity.

What is emotional arousal?

Emotional arousal is the physiological and psychological responses to an emotional stimulus. It's a term that describes a wide range of feelings and physiological responses associated with our emotions. Our physiological and psychological responses to emotions, such as fear or happiness, are called emotional arousal. These responses can include a variety of changes, such as increases or decreases in heart rate, changes in breathing, sweating, changes in the dilation of the pupils, and other changes that are closely linked to our emotional states.

Bears are considered dangerous animals, so if you ever encounter one, you must be prepared. Your emotional arousal would be accompanied by constriction of pupils to increase visual acuity, which would allow you to have a better view of your surroundings. This would aid you in responding to the situation appropriately.

Which of the following characteristics is not associated with bronchiolitis? Thick, tenacious mucus Wheezing Crackles Bradypnea

Answers

The characteristic that is not associated with bronchiolitis is "Bradypnea" (slow breathing). Bronchiolitis is a common respiratory infection that primarily affects young children, usually under the age of two. It is typically caused by a viral infection, most commonly respiratory syncytial virus (RSV).

Thick tenacious mucus is a characteristic associated with bronchiolitis. The infection leads to inflammation and swelling of the bronchioles, which are the small airways in the lungs. This can result in the production of thick mucus that obstructs the airways, causing difficulty in breathing. Wheezing is another common characteristic of bronchiolitis. It is a high-pitched whistling sound that occurs when air passes through narrowed or partially blocked airways.

Crackles, also known as rales, are abnormal sounds heard during breathing. They indicate the presence of fluid or mucus in the airways. However, Bradypnea, or slow breathing, is not typically associated with bronchiolitis. In bronchiolitis, the breathing pattern is often rapid and shallow due to the increased work of breathing caused by airway obstruction and inflammation.

in which location will the fetal heart tones be heard if the fetus position is left occiput anterior

Answers


The fetal heart tones will be heard on the left side of the mother's abdomen if the fetus is in a left occiput anterior position.  The fetal heart tones in a left occiput anterior (LOA) position can be heard in the lower left quadrant of the mother's abdomen, near the left iliac crest.


The left occiput anterior (LOA) position refers to the position of the fetus with the back towards the left side of the mother's abdomen and the head facing downwards. In this position, the fetal heart tones are most easily heard on the left side of the mother's abdomen, as the baby's back is facing towards the mother's front. The healthcare provider may use a fetal Doppler or stethoscope to detect the fetal heart rate, which is an important indicator of the baby's health and wellbeing during pregnancy.

In a LOA position, the baby's head is down and facing the mother's left side, with the back of the head towards the front of the mother's body. To locate the fetal heart tones, place a fetal doppler or stethoscope in the lower left quadrant of the mother's abdomen, close to the left iliac crest. The best spot to hear the heart tones may vary slightly, so it might be necessary to move the listening device around this area until the heart tones are clearly audible.

8. A scientists is studying a normal tissue and a cancerous tissue sample. What method might she use to determine whether the transcription of gene X is upregulated in the cancerous tissue sample

Answers

To determine whether the transcription of gene X is upregulated in the cancerous tissue sample as compared to the normal tissue, the scientist can use the method of quantitative reverse transcription polymerase chain reaction (qRT-PCR).

This technique can quantify the amount of RNA transcript of the gene of interest in each sample. It involves reverse transcription, where RNA is reverse transcribed to complementary DNA (cDNA), followed by PCR amplification of the cDNA using gene-specific primers and a fluorescent probe. The fluorescence intensity is proportional to the amount of cDNA produced during the PCR. The threshold cycle (Ct) value is calculated by detecting the cycle number at which the fluorescence intensity crosses a certain threshold value. The Ct value is inversely proportional to the amount of RNA in the sample. By comparing the Ct values of gene X in the normal and cancerous tissue samples, the scientist can determine whether the gene is upregulated in the cancerous tissue. If the Ct value of the gene in the cancerous tissue is lower than that in the normal tissue, it indicates that the gene is upregulated.

Answers

At a transform fault boundary, such as the San Andreas Fault, plates slide past each other and a. have a tendency to stick and build up energy that will result in a future earthquake.

This occurs because the irregularities of the plates' edges cause friction, preventing smooth movement. As the plates continue to move, stress accumulates until it reaches a point where the stored energy is released in the form of an earthquake. This process is known as elastic rebound theory. Option B is incorrect, as rock melting typically occurs at convergent or divergent boundaries, not transform boundaries.

Option C is also incorrect because new crust formation is associated with divergent boundaries, where plates move apart, rather than transform boundaries, where plates slide past each other without creating or destroying crust. In summary, the correct answer is a. have a tendency to stick and build up energy that will result in a future earthquake. At a transform fault boundary like the San Andreas Fault, plates tend to stick, build up energy, and eventually release that energy through earthquakes.
