Answer:
Meiosis
Explanation:
Meiosis is a cell division that takes place in the germ cells. The formation of human gametes is called gametogenesis.
In the process of meiosis, germ cells are formed from diploid, stem cells of spermatogonia and oogonia, ie. male and female gametes containing a haploid number of chromosomes, or half less than somatic ones. The importance of meiosis is reflected in the maintenance of a constant number of chromosomes from generation to generation.

From the given information.
Let the Straight stamens be S;
The incurved stamens be s;
The red petals be R; and
The streaky petals be r
The genotype of the parental plants are Straight stamens, red petals (SsRr) and Straight stamens, streaky petals)
So if SsRr and Ssrr crossed together, Then we have the following:
If SsRr self crossed, we have the following traits = SR Sr sR sr; &
Ssrr = Sr Sr sr sr
Then, the dihybrid cross is:
SR Sr sR sr
Sr SSRr SSrr SsRr Ssrr
Sr SSRr SSrr SsRr Ssrr
sr SsRr Ssrr ssRr ssrr
sr SsRr Ssrr ssRr ssrr

Which of the following describes the amount of organic material that is available for transfer to the next trophic level after subtracting material
used for respiration?
Biomass
Gross Primary productivity
Net Primary productivity
Primary productivity
Answer:
Net Primary productivity
Explanation:
In an ecosystem, primary productivity is a term used for autotrophic organisms. It is the process by which these organisms like plants, green algae etc. make their own food using inorganic sources. However, they do not utilize all the matter they make from this process.
The NET PRIMARY PRODUCTIVITY (NPP) is the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration. This means that NPP is the amount available after removal of the one to be lost via respiration i.e. NPP = GPP - respiration.
Question: "Which of the following describes the amount of organic material that is available for transfer to the next trophic level after subtracting material?"
Answer: "Out of the options given prior to the question, Net Primary productivity is the best choice. The answer alone can be determined through the definition of the word. Net Primary productivity literally is the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration. Hence, the correct choice is C."

Mary has always been very healthy. Even though all her friends have been verysick with the flu this year, she does not feel like she
needs to get a flu shot. Mary has what perception towards risk?
a. degree of control
b. instant gratification
c. optimism bias
d. catastrophe
Optimism bias is the perception towards risk that Mary has.
The optimistic bias is a term to refer to the human tendency to see the future positively and better compared to the past and the present. The optimistic bias includes the tendency to underestimate the possibility of negative things happening, such as illness, car accidents, and unemployment.
According to the above, Maria has a perception of optimistic bias because she is underestimating the possibility of getting sick even though all of her friends have gotten sick. This may be reinforced by the fact that she is in good health and that is why she does not think it is necessary to get vaccinated.
Additionally, the degree of control, instant gratification, and catastrophe options are not correct options because they are types of perception different from optimistic bias.

Coat color in cats is a codominant trait and is located on the X chromosome. Cats can be black, orange, or calico. A calico cat has black and orange splotches. In order to be calico, the cat must have an allele for the black color as well as an allele for the orange color. Also located on the X chromosome of a cat is a gene that codes for deafness. The gene is recessive. A black female cat that is heterozygous for deafness (Dd) is crossed with a male orange cat that is not deaf. Show the cross. What are the phenotypes of the offspring and in what proportion? (Hint: Place two superscript letters on the X chromosome in your cross.)

What does an increased pulse rate indicate about the heart rate
Answer:
A high heart rate can also mean the heart muscle is weakened by a virus or some other problem that forces it to beat more often to pump enough blood to the rest of the body. Usually, though, a high heart beat is not due to heart disease, because a wide variety of noncardiac factors can speed the heart rate.

In the ocean, they provide a crucial source of food to many small and large aquatic organisms, such as bivalves, fish and whales.
A change in DNA could alter the amino acid order which will affect the folding of the protein, and therefore it's function. True or false
Answer:
The gene, or sequence of DNA, ultimately determines the unique sequence of amino acids in each peptide chain. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and therefore function
Explanation:
The statement "a change in DNA could alter the amino acid order which will affect the folding of the protein, and therefore its function" is definitely true.
What are amino acids?Amino acids may be defined as the monomers of the building blocks of proteins. These compounds contain carbon, hydrogen, nitrogen, and oxygen. Amino acids are generally composed of an amino group, a carboxyl group, a hydrogen atom, and a distinctive side chain.
The sequence of DNA is made on the foundation of amino acids along with nucleotides. These sequences govern the special function with respect to their coding and folding. Each sequence specifies a particular protein.
A little change or alteration in these sequences may direct the formation of different amino acids. This completely changes the folding of the protein. This means that the physiology of the protein structure change which also affects its function.
Therefore, the statement "a change in DNA could alter the amino acid order which will affect the folding of the protein, and therefore its function" is definitely true.

Answer: Magnolia is a large genus of about 210 flowering plant species in the subfamily Magnolioideae of the family Magnoliaceae. It is named after French botanist Pierre Magnol. Magnolia is an ancient genus. Appearing before bees did, the flowers are theorized to have evolved to encourage pollination by beetles. To avoid damage from pollinating beetles, the carpels of Magnolia flowers are extremely tough. Fossilized specimens of M. acuminata have been found dating to 20 million years ago, and of plants identifiably belonging to the Magnoliaceae date to 95 million years ago. Another aspect of Magnolia considered to represent an ancestral state is that the flower bud is enclosed in a bract rather than in sepals; the perianth parts are undifferentiated and called tepals rather than distinct sepals and petals. Magnolia shares the tepal characteristic with several other flowering plants near the base of the flowering plant lineage such as Amborella and Nymphaea.

Change the following sequence (GGAUUC) to show:
a. Substitution
b. Insertion
c. Deletion
Answer:
Given the sequence of bases of the RNA GGAUUC, the possible mutations would be:
a. Substitution: GGAUUC → GGAAUC
b. Insertion: GGAUUC → GGACCUUC
c. Deletion: GGAUUC → GG_UC
Explanation:
The fragment observed is recognized as RNA, due to the presence of uracil (U). The mutations observed in this fragment are derived from a mutated DNA molecule, which was transcribed into mRNA
Substitution is a molecular mutation that occurs when one nitrogenous base is changed to another in the DNA sequence. GGAUUC → GGAAUC Mutated DNA: CCTTAGInsertion occurs when entire bases or segments are added to the original genetic material, resulting in a longer molecule. GGAUUC → GGACCUUC Mutated DNA: CCTGGAAGDeletion is a type of mutation where genetic material is lost, which can be nitrogenous bases or segments of the molecule. GGAUUC → GG_UC Mutated DNA: CC_AGEach of these mutations can have an effect on protein synthesis, affecting the structure or function of the final protein.
