A veterinarian conducts a study of meiosis in dogs. She observes that during anaphase I, there are 39 pairs of chromosomes being pulled toward opposite ends of the cell. Which of the following statements is false? A. Crossing over has already taken place. B. The diploid number for dogs is 78. C. There will be 39 chromosomes in each dog gamete. D. Each gamete will have two alleles for each gene.
Answer:
D. Each gamete will have two alleles for each gene.
Explanation:
Gametes are haploid (n) reproductive cells. In animals, female gametes are known as egg cells, while male gametes are sperm cells. Each gamete (either female gamete or male gamete) contains a complete set of chromosomes which in turn have a complete set of gene variants (i.e., alleles). In consequence, for each gene, the dog's progeny will inherit one allele from the father and one complementary allele from the mother, thereby having a diploid (2n) number of homologous chromosomes.

A calico cat shows both the traits for orange fur and black fur.
What kind of allele expression is this?
Codominance
Explanation: Becuase both of the traits are showing.
The allele expression in the case of a calico cat which shows both the trait for orange fur and black fur is Codominance.
Codominance is a hereditary model that states that in the heterozygous there is no recessive allele, but on the contrary, both alleles behave as dominant and both manifest themselves without mixing.
Codominance is an important aspect of the crossing process because the two allele genes are expressed, but not joined. An example of this is calico cats that have two X chromosomes in each of their cells.
In calico cats, the gene for the orange fur is located on the X chromosome and they have one allele for the black fur. The only way that both alleles occur together and combined with white is that there are two X chromosomes and these are codominant or these express at the same time.

Which of the following cell types of the innate immune system does not perform phagocytosis? And Why?
Neutrophils, Basophils, Macrophages, Eosinophils
Answer:
Macrophage
Explanation:
Monocytes move from the systemic circulatory system into general connective tissues, where they differentiate into what phagocytic cell type?
I think...
Basophils are cells of the innate immune system that does not perform phagocytosis. These cells (basophils) release granules of enzymes to fight against harmful microorganisms and recruit other inflammatory cells.
When harmful microorganisms (e.g., bacteria) or potentially harmful particles enter the body, different cells of the immune system respond by trying to isolate and destroy them.
Phagocytosis refers to the biological by which phagocytic cells ingest/engulf other cells (e.g., bacteria) or harmful particles.
Phagocytic cells of the immune system include neutrophils, macrophages, and dendritic cells.
Basophils are white blood cells that are responsible for releasing granules of enzymes to fight against harmful microorganisms (e.g. bacteria) and recruit other inflammatory cells (e.g., macrophages, eosinophils) to the site of infection.

The diagram below shows the process of translation.
What is represented by the structure labeled 2?
Answer:
The structure labeled 2 is tRNA, transfer RNA.
Explanation:
In this given diagram, the translation process is explained. The tRNA is represented by the lebel 2. tRNA carries the amino acid that makes the polypeptide chain .
What is the translation process?Translation is a process by which a polypeptide chain is formed using enzymes, energy sources such as ATP/GTP, mRNA, tRNA, and amino acids. It is an active process, so energy is used. The DNA, which consists of genes, codes for some characters. These characters are expressed in the form of proteins by the translation process.
In the given diagram, the mRNA is read by ribosomes, and tRNA reads the codons of mRNA. The ribosome reads from the 5' to 3' end of mRNA and adds amino acids.
Ribosomes have three sites: the A (acceptor site), the P (peptide site), and the E (exit site). Amino acid with tRNA is called charged tRNA. The charged tRNA binds at the A site, peptide bonds form at the P site, and the tRNA exits at the E site. Level 2 represents these tRNAs without amino acids.
Hence, lebel 2 explains the tRNA .

D
starch and sucrose
Answer:
A. amino acids and protein
The vascular tissue that transports the products formed during photosynthesis from their leaves to the base regions is called phloem.
The phloem transports the following:
Option B. Amino acids and sucrose.
This can be explained as:
The plants have a transport system for transporting nutrients, minerals and fluids.The two types of systems are phloem and xylem.The phloem transports the sugars (sucrose) and amino acids dissolved in water.The xylem is responsible for transporting minerals and water.
Therefore, phloem transports amino acids and sucrose.

Do you think this dissolving process is the same for non-polar molecules as it is for the polar molecules?
Answer:
Atoms seek more stable states. The structure of an atom is similar to that of the solar system. The large protons with a positive charge and neutrons with no charge are found at the nucleus or center. The tiny electrons with negative charges circle rapidly in orbits around the nucleus, forming electron shells at different distances, much like the planets and other objects that circle the sun. Atoms of each element have varying numbers of electrons in their outermost shells.

Please find the answers in the appropriate blank spaces in the sentence in BOLD.
Explanation:
As a result of photosynthesis, PLANTS synthesize organic compounds tha they use as a source of ENERGY. Photosynthesis converts SOLAR energy into CHEMICAL energy. Inside a CHLOROPLAST, chlorophyll pigments absorb LIGHT energy. This energy is then transferred to two chemical compounds; ATP and NADPH. These compounds are made in a set of reaction known as the LIGHT-DEPENDENT REACTION. These compounds are then used to drive another set of reactions known as the LIGHT-INDEPENDENT REACTION or CALVIN CYCLE. This second set of reactions changes CO2 into organic compounds known as SUGARS/CARBOHYDRATES.
The OXYGEN that is produced in photosynthesis comes from water molecules that split by LIGHT energy. As a result of photosynthesis, CO2 and WATER are changed into GLUCOSE and OXYGEN. The products of photosynthesis are used in another process called CELLULAR RESPIRATION, while photosynthesis is carried out only by PLANTS/AUTOTROPHS, respiration is carried out by both PLANTS/AUTOTROPHS and ANIMALS/HETEROTROPHS.
According to the question the answer in the blank space are as follow:
1. Plants
2. Energy

4. Chemical
5. Chloroplast
6. Light
7. ATP
8. NADPH

which statement best explains why correct protein folding is critical in the transmembrane protein shown above?
Answer:
- Interactions of the hydrophobic and hydrophilic amino acids help to anchor the protein in the membrane.
Explanation:
The above statement correctly defines that it is significant to fold protein correctly in the transmembrane protein as displayed above because the 'interactivity along the hydrophilic and the hydrophobic amino acids assist in harboring the protein in the membrane.' These 3-dimensional structures have a specific biological significance and promote better functioning. The incorrect folding of protein may give rise to numerous diseases.
Interactions of the hydrophobic and hydrophilic amino acids help to anchor
the protein in the membrane is the statement that best explains why correct
protein folding is critical in the transmembrane protein.
Protein consists of amino acids in a 3 dimension form and its correct folding
aids its optimal functioning. In a protein structure, there are interactions of
the hydrophobic and hydrophilic amino acids which acts as a strong anchor.
The hydrophobic parts of amino acids help to interact with the long chains
of the fatty acids in lipid bilayer while the hydrophilic part of amino acids
assist to interact with water on the surface of the cell membrane.
