Answer:
review all proposals for animal research to be sure the procedures to be used are appropriate and humane.
Explanation:
The Institutional Animal Care and Use Committee (IACUC) is a federal committee responsible for approving and/or prohibiting the use of animal (nonhuman vertebrate) subjects for research, testing and teaching purposes, as well as the inspection of animal facilities. IACUC evaluates the institution's animal programs and procedures as described by the Office of Laboratory Animal Welfare (OLAW). This committee has the task to verify animal's well-being by minimizing pain and distress (for example, by ensuring the use of non-invasive methods when possible). Researchers/educators that use animals for research/teaching purposes must previously submit a written request defined by the IACUC's guidelines.

Figure 1 shows an image of a diseased plant. The fungus causes pollen to be replaced with powdery, dark colored spores. The fungus is spread by pollinators. What structure of the flower is most likely impacted by this fungus?
The anthers of the flower are most likely impacted by this fungus.
What is a fungus?
Fungus is a type of organism that is neither a plant nor an animal. It is a member of a group of organisms called eukaryotes, which includes all living things except bacteria and viruses. Fungi are made up of microscopic cells organized into long, branching structures called hyphae. Fungi are extremely diverse and can be found in all types of habitats, from soils and plants to animals, including humans. Fungi play important roles in the ecosystem, breaking down dead organic matter, cycling nutrients, and providing food for other organisms.
The anthers are the organs responsible for producing and releasing pollen, so if they are replaced with powdery, dark colored spores, the flower will be unable to produce viable pollen.

Daddy #2 has blood type AB. Who is the true Baby Daddy? Explain how you
know
Start with what you know first:
child's genotype
Mother's genotype.
Daddy #1
Daddy #2_
remember that the child gets one gene from each parent
Based on the genotypes provided, it is not possible to determine who the true Baby Daddy is.
Who is the true Baby Daddy?This is because the child would need to have the same genotype as one of the two possible fathers in order for it to be determined that one of them is the true father. Since the child has a blood type of A, and neither Daddy #1 or Daddy #2 have the same type, it cannot be determined which one is the true father.The process of determining the biological father of a child is known as paternity testing. To determine paternity, the child's blood type (A) and the mother's (B) must be known. Baby Daddy #1 has a blood type of O, while Baby Daddy #2 has a blood type of AB. From this information, we can deduce that Baby Daddy #2 is the true biological father.The mother's genotype must include both an A and a B gene, since the child's blood type is A. Baby Daddy #1's genotype must contain two O genes, as his blood type is O. Baby Daddy #2 is the only possible father, since his genotype must contain one A gene and one B gene in order for the child to have a blood type of A. By testing the blood types of the mother, the potential fathers, and the child, we can determine the true biological father. This process is known as paternity testing, and it is useful for determining the legal father of a child, as well as for providing medical information to parents and their children.To learn more about paternity testing refer to:

Answer: a
Explanation:..
Gradualism and punctuated equilibrium have in common as they are both explanations of the rate of evolutionary change.
Option A is correct.
Gradualism and punctuated:The evolution of a species can take place in two different ways: punctuated equilibrium and gradualism.
Selection and variation that occurs more gradually is referred to as "gradualism." It's hard to notice in a short amount of time. For the following reasons, organisms are chosen for small variations that are slightly more suited to their environment: Those with more of the helpful quality live to see another day, while those with less of it pass away.
Change occurs in spurts in punctuated equilibrium. There is a time when very little changes, and then one or a few big changes happen, usually through genetic mutations in a few people. Random changes in DNA that are passed on to subsequent generations rather than being inherited are known as mutations.

how many codons would be needed to code for a protein that has 50 amino acids
A codon is a sequence of three nucleotides that codes for a specific amino acid. In order to code for a protein that has 50 amino acids, it would require 50 codons.
This is because each amino acid is coded for by a specific codon, and the sequence of codons determines the sequence of amino acids in a protein. Since there are 20 common amino acids used in proteins, and the genetic code is redundant, more than one codon can code for the same amino acid.
It's important to note that the genetic code is redundant, meaning that more than one codon can code for the same amino acid, this means that the total number of codons used to code for a protein with 50 amino acids may be greater than 50.

Bacteria and viruses can only survive on a dry surface for about two hours is false.
The survival time of bacteria and viruses on a dry surface can vary widely depending on the type of microbe, the conditions of the surface, and the environment.
Some bacteria and viruses can survive for extended periods on dry surfaces, while others may die off quickly.
For example, non-enveloped viruses such as norovirus and adenovirus can survive for several days on dry surfaces, while enveloped viruses such as influenza and rhinovirus can survive for only a few hours on dry surfaces.
Bacteria such as Staphylococcus aureus can survive for several days on dry surfaces, while others such as Escherichia coli may only survive for a few hours.
