Answer:
photosynthesis occurs in the chloroplast of plant cells. cellular respiration starts in the cytoplasm then reacts in the mitochondria. if you look at the chemical equation of both photosynthesis and cellular respiration they are reverse of each other. in cellular respiration sugar goes in with oxygen, what comes out is ATP(energy), water, and carbon dioxide gas. in photosynthesis energy, water, and CO2 goes in and what is made is sugar and oxygen. The main purpose of cellular respiration and photosynthesis is to make energy and to store energy for later use.

tatuo aida what progeny genotype would you expect for a cross between a homozygous red fish and a white fish?
For a cross between a homozygous red fish and a white fish, the progeny genotype would be Rr.
The genotype is the entire set of genes that are present in an individual, including those responsible for observable characteristics and those that are not. Genotypes can be homozygous, which means they contain two identical alleles for a specific trait, or heterozygous, which means they contain two different alleles for a specific trait.
In this question, the homozygous red fish contains two identical alleles for red coloration, which is denoted as "RR." On the other hand, the white fish does not have any alleles for red coloration, which is denoted as "rr."
As a result, when these two fish are crossed, all of the offspring will have one allele for red coloration (R) and one allele for white coloration (r), making them all Rr heterozygotes.

The diagram shows a simplified version of how the blood moves around the body of an animal. Which organ(s) is found at point X?
Answer:
lungs
Explanation:
Why? Because the lungs supply the blood with Oxygen that's why blood goes into organ x with (blue) no oxygen and comes out with (red) Oxygen
The heart pumps blood throughout our body with each beat, supplying oxygen to every cell. Blood returns to the heart after supplying oxygen. The blood is subsequently sent to the lungs by the heart so that it can absorb additional oxygen.
What is the process of blood purification by lungs?When breath is inhaled, impure blood comes into touch with oxygen from the air and absorbs it. The waste material in the blood causes the release of carbonic acid, which purifies the blood. The veins deliver the cleaned blood to the heart.
Due to the high partial pressure of oxygen in the lungs, where hemoglobin has a strong affinity for oxygen, the blood is cleansed in the lungs, turning deoxygenated blood into oxygenated blood.
Then, through pulmonary veins, the cleansed blood leaves the lungs and reaches the left atrium.
Therefore, Because the lungs supply the blood with Oxygen, that's why blood goes into organ x with (blue) no oxygen and comes out with (red) oxygen.

Proteins are synthesized: Group of answer choices Amino to carboxy terminal 3'-to-5' Carboxy to amino terminal 5'-to-3'
Proteins are synthesized from the N-terminus to the C-terminus. This is also known as the amino (N-) terminus to the carboxyl (C-) terminus.
The correct option among the given alternative is "amino to carboxy terminal".
Explanation:
DNA instructions are transformed into the amino acid sequence of a protein through a process known as transcription and translation, which occurs in the ribosome. The N-terminus and C-terminus of a protein are the two endpoints. The N-terminus of a protein contains the first amino acid in the sequence, which is often referred to as the start methionine. The C-terminus of a protein contains the last amino acid in the sequence. The end of the polypeptide chain is referred to as the carboxy terminus. The amino acid sequence of a protein is determined by the sequence of nucleotides in the mRNA molecule. This sequence is read in sets of three nucleotides, known as codons. Each codon specifies a particular amino acid to be added to the growing polypeptide chain. The process of protein synthesis always starts at the N-terminus, where the first amino acid is attached, and ends at the C-terminus, where the last amino acid is attached. Therefore, proteins are synthesized from the amino to carboxy terminal end.

Explain the three mechanisms that contribute to genetic variations in sexual life cycle.
The three mechanisms that contribute to genetic variations in the sexual life cycle are crossing over, independent, assortment, and fertilization.
The three mechanisms that contribute to genetic variations in the sexual life cycle are as follows:
1. Crossing over: During the process of meiosis, homologous chromosomes exchange segments, which results in the production of new combinations of alleles. This process is known as crossing over and contributes to genetic variation.
2. Independent assortment: During the process of meiosis, the arrangement of chromosomes is random, leading to the independent assortment of alleles. This also contributes to genetic variation, as different combinations of alleles are produced.
3. Fertilization: The process of fertilization involves the fusion of two haploid gametes to form a diploid zygote. As different gametes can fuse together during fertilization, this also contributes to genetic variation.
In conclusion, the three mechanisms that contribute to genetic variations in the sexual life cycle are crossing over, independent assortment, and fertilization.

based on the principle of independent assortment, which of the following statements is true?
a)Independent assortment leads to variation.
b)Independent assortment leads to formation of new combinations of characters.
c)Factors assort independent of each other when more than one pair of characters are present together.
d)All of these
The principle of independent assortment, the following statements is true : The correct answer is d) All of these.
The principle of independent assortment is one of Mendel's laws of inheritance. It states that during the formation of gametes, the segregation of alleles for one gene is independent of the segregation of alleles for another gene. This means that the alleles for different traits or characters segregate independently of each other.
The independent assortment of alleles during gamete formation leads to variation (option a) because it allows for the creation of new combinations of alleles. When different genes assort independently, they can randomly combine in offspring, resulting in different combinations of traits or characters (option b).
Option c) is also true. When more than one pair of characters or traits are present together, the factors (alleles) for those traits assort independently of each other. This means that the inheritance of one pair of alleles does not influence the inheritance of another pair of alleles.
Therefore, all three statements are true, and the correct answer is d) All of these. The principle of independent assortment plays a crucial role in generating genetic diversity and the inheritance of multiple traits in sexually reproducing organisms.

What can affect the outcome of a cross, causing scientists to reject the independent assortment hypothesis, even though it may be correct?
There are several factors that can affect the outcome of a cross, leading scientists to reject the independent assortment hypothesis even if it is correct. One of the most important factors is genetic linkage.
If two genes are located close to each other on the same chromosome, they are more likely to be inherited together rather than independently. This can create deviations from the expected Mendelian ratios in the offspring. Another factor is epistasis, which occurs when one gene affects the expression of another gene. This can also lead to unexpected ratios in the offspring.
In addition, environmental factors such as temperature, nutrition, and exposure to toxins can influence gene expression and therefore affect the outcome of a cross. Therefore, it is important for scientists to carefully consider all possible factors that could affect the outcome of a cross before drawing any conclusions.

T/F ttx resistance originated as a mutation in the nucleotide sequence of gene that codes for sodium channels in the skeletal muscles of snakes.
The given statement "tetrodotoxin (TTX) resistance in snakes originated as a mutation in the nucleotide sequence of a gene that codes for sodium channels in their skeletal muscles" is True. Tetrodotoxin is a potent neurotoxin found in certain animals, such as pufferfish, and is known to block voltage-gated sodium channels in nerves and muscles.
In some snake species, particularly those that prey on toxic animals like the pufferfish, the ability to resist TTX is crucial for survival. These snakes have evolved a resistance to TTX by developing mutations in the genes encoding their sodium channels. Specifically, the mutation occurs in the gene that codes for the α-subunit of the voltage-gated sodium channel (Nav1.4) in skeletal muscles. As a result, it can cause paralysis and even death in many organisms.
The mutation leads to a change in the amino acid sequence of the sodium channel protein, which in turn alters its structure and function. This alteration reduces the binding affinity of TTX to the channel, making it less sensitive to the toxin and allowing the snake to survive despite ingesting a TTX-containing prey.
This evolutionary adaptation provides a significant advantage for these snakes, as it enables them to exploit a niche in their environment by feeding on toxic prey without suffering the lethal effects of TTX. In summary, TTX resistance in snakes is a result of a mutation in the nucleotide sequence of a gene coding for sodium channels in their skeletal muscles, enabling them to survive in their unique ecological niche.
