Answer: C. Multicellularity

Explanation:

Multicellularity is an evolutionary process in which a single cell organism can specialize and become a multicellular organism. It has been present in some kingdoms. To consider that an organism is multicellular the cells have to adhere to each other, communicate, cooperate, and have specialized functions.

A cell has been subjected to X-ray irradiation, causing a significant number of mutations in the genome. Which of the following

MakcuM [25]

Answer:

D. Binding of p53 to Mdm2

It has nothing to do with Xray irradiation.

Explanation:

Mdm2 is a protein regarded as the main regulator of tumor suppressor protein P53. P53 Inactivation by mutation is seen as one of the most frequent alterations in tumors that affects humans.

The central binding p53 site of Mdm2 encloses amino acid. The binding of p53 to the central Domain is strengthened after the process of phosphorylation of the central Mdm2 domains.

The pharmacy technician should avoid spraying any substances into the ____________________ when cleaning the laminar airflow hoo

denis-greek [22]

The right answer is HEPA filter.

A HEPA filter (High Efficiency on Particles Air) can filter up to 99.97% of 0.3μ aerial particles.

These filters are used to clean the air and retain suspended particles (dust, pollen, bacteria etc.) and other particles that can cause respiratory allergy in sensitive subjects.

They are very used in sterile rooms

If the circulatory system failed what would happen to the heart rate?

Gelneren [198K]

The heart rate would decrease because there is less oxygen being supplied to the cells for cellular respiration, and also your muscles won't get the blood it needs. Blood also contains oxygen and glucose which cells need to convert food to energy and to survive, so if the cells don't get blood they will die which will eventually kill the organism

The cladogram shown below describes the evolutionary relationship among several species, labeled A to F. The five dots represent

max2010maxim [7]

(You will find the cladogram in the attaches files)

Answer:

C. The genomes of species C and D are nearly identical because neither species has a derived character.

Explanation:

A Cladogram is a tree-type graph based on cladistic analysis. It represents the common ancestral relationships among the involved groups.

The tree-type graph is a ramified diagram that represents the relationship between the involved taxa.
The cladistic analysis follows the maximum parsimony criterium. Explains the character state from the point of view of the fewest changes through history. Explains evolution with the minimal amount of evolutive changes. It recognizes the monophyletic groups as natural groups. These groups are the clades, and their classification -sequencing- represents their phylogeny.

The sequencing term refers to lists of groups according to their relation. One group is the brother-group of the following one.

So the cladogram represents the relationship between groups according to a derived character.

The derivated character is any trait that a group passes to the descendants. Through evolution, the characters change, and new changes are added. When referring to a derivate character, we mean that all the subsequent species in the cladogram carry the trait.

A cladogram provides an image of how new species keep characters that were inherited from older species.

So, in the exposed example, the five dots represent derived characters, representing traits 1 to 5. Branches A to F, represent groups. (See the cladogram in the attached files). Group A inherited trait 1, group B probably still carries trait 1, but also trait 2. Groups C and D equally inherited trait 3. Group E inherited character 4, and finally, group F inherited character 5.

Groups C and D inherited trait 3 and probably also still have traits 1 and 2. So they are very similar to each other. At a certain point, they diverged, probably due to a new mutation that was not passed to the rest of the group.

C. The genomes of species C and D are nearly identical because neither species has a derived character. Correct.

The concept of __________ means that because of their genetic makeup, individuals differ in their responsiveness to qualities of

Leni [432]

Answer: Behavioral genetics

Explanation: This concept indicates that our genes influence our environment and in return, the environment influences our genes. Behavioural genetics has therefore expressed gene-environment interactions on the behaviour of an individual.
