Answer:  

Hox genes are thus a subset of the homeobox transcription factor genes. In many animals, the organization of the Hox genes in the chromosome is the same as the order of their expression along the anterior-posterior axis of the developing animal, and are thus said to display colinearity.

Explanation:

Hox genes, a subset of homeobox genes, are a group of related genes that specify regions of the body plan of an embryo along the head-tail axis of animals. Hox proteins encode and specify the characteristics of 'position', ensuring that the correct structures form in the correct places of the body.

Chromosomes are thread-like structures present in the nucleus, which carries genetic information from one generation to another. They play a vital role in cell division, heredity, variation, mutation, repair and regeneration.

Answer:

The Law of Conservation of Mass.

Explanation:

The reasoning behind this is that when the chemical equation is balanced, so is the amount of mass. We make sure that the chemical equation is balanced to ensure that the law of conservation of mass is conserved. This is why we add coefficients to the beginning of reactants and products to make sure that the mass of the reactants combined is the same amount of mass of the products combined.

Answer:

The Law of Conservation of Mass!

Explanation:

In photosynthesis, light energy from the sun is converted into chemical energy and is stored.

Photosynthesis is a method that plants and other organisms use to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration.

Photosynthesis is the conversion of light energy by phototrophs into chemical energy, which is then used to power cellular activities.

Sugars, which are formed from water and carbon dioxide, are used to store chemical energy.

Animals require oxygen to survive, and plants serve as nature's air filter, filtering out harmful carbon dioxide.

Thus, this way, the light energy gets converted into chemical energy.

Explanation:

A nurse is caring for an adolescent who has hemophilia A and is scheduled for wisdom teeth extraction. Before the procedure, the nurse should anticipate that the client will receive fresh frozen plasma.

What is Hemophilia A?

Hemophilia A is a genetically inherited bleeding disorder in which the blood cannot clot normally. People with hemophilia A have low levels of clotting factor VIII, a protein that helps blood to clot. As a result, they may experience prolonged bleeding after an injury or surgery.

Hemophilia A is more common in males than in females and can be mild, moderate, or severe. The nurse caring for an adolescent who has hemophilia A and is scheduled for wisdom teeth extraction should anticipate that the client will receive fresh frozen plasma.

Clotting factors present in blood:

Fresh frozen plasma contains clotting factors that can help the client's blood clot normally and prevent excessive bleeding during and after the procedure. Prophylactic antibiotics are often given before dental procedures to prevent infection but do not help with bleeding disorders such as hemophilia A. Packed red blood cells (PRBCs) and recombinant factor VIII concentrate may be used in severe cases of bleeding, but fresh frozen plasma is typically the first-line treatment for bleeding disorders.

Explanation:

Answer:

kinda blurry so I hope I answered everything correctly!

A. The Linear equation would be x + y = 50

B. Ted spends 35 minutes practicing the breaststroke every day.

Ted spends 50 minutes every day swimming so x +y = 50 (let us say x is butterfly stroke and y is breaststroke). Since he practices the breaststroke for 20 more minutes than the butterfly stroke we have:

2x + 20 = 50

2x = 50 - 20

2x = 30

x  =30 / 2

x  = 15

y = 15 + 20  =35 minutes

C. No, it is not possible for Ted to have spent 45 minutes practicing the butterfly stroke every day because of the time constraint.

Aristotle believed that species are fixed forms that do not change over time while Lamarck believed that evolution is the refinement of traits that equip organisms to perform successfully in their environments.

According to Aristotle, the highest and most significant role that nature could do was to serve some purpose in a human being's existence. Everything in nature, from the heavens to plants, was made to serve this goal.

He opposed the theory of Natural selection and held the view that the world was composed of distinct individuals (substances) existing within specific natural sorts (species). Every individual has patterns of development that are already present that guide its growth towards becoming a fully grown individual of its kind. Each individual has development, purpose, and direction patterns embedded into them by nature.

Jean Baptiste Lamarck, a French naturalist, proposed that life evolves in the early 1800s and described this evolution as the improvement of features that enable creatures to successfully function in their environment.

Explanation:

The correct sequence of steps that takes place during the formation of de-etiolation (greening) response proteins in plants is as follows:

i. Reception of light signal by phytochrome

ii. Activation of second messengers

iii. Formation of de-etiolation response protein

The De-etiolation response or greening response is a plant's reaction to light, which includes elongation and leaf expansion. De-etiolation, which results in the development of photosynthetic structures, happens when the seedlings or shoot get exposed to sunlight or other sources of light.

Phytochrome is crucial in plants since it plays a role in light signaling and sensing. Phytochromes absorb red and far-red light, converting the light into a biochemical signal that initiates several developmental procedures. The activation of second messengers such as Ca2+, inositol triphosphate (IP3), and diacylglycerol (DAG) is crucial in initiating a series of biochemical and genetic changes that eventually lead to the production of green pigments during the formation of de-etiolation response protein.

Answer:

senescence

Explanation:

Senescence is when the cell loses its ability to replicate hence it does not divide.

When a cell leaves the cell cycle and no longer undergoes division is defined as the stage of senescence. In this condition, the cell stops replicating. Thus, the correct option is A.

Cell cycle is the order of events which takes place in the cell throughout its life. Cell cycle includes the growth of cell and division to form new daughter cells similar to the parent cell.

Cell cycle is divided into Interphase and M-phase. Interphase is the stage where the cell prepares itself for the actual cell division and it consists of G1 phase, S phase, and G2 phase. In these phases, cell grows in size and replicates its genetic material. In the M-phase, the actual cell division takes place. M-phase is divided into karyokinesis and cytokinesis, to form two daughter cells.

If a cell stops dividing and leaves the cell cycle. Then, the cell is said to enter the senescence stage where it is no longer an active cell.

Therefore, the correct option is A.
