Answer:

is a result of the absence of macrophages or B cells.

Explanation:

Severe combined immunodeficiency (SCID) results due to the absence of macrophages or B cells that is responsible for the immunity of  our body. Severe combined immunodeficiency (SCID) is an inherited immunodeficiency disease (PIDD) that presents in infancy results  in a weak immune system that is unable to fight against even mild infections so due the absence of macrophages or B cells, the body is vulnerable to diseases.

Answer:

Forms of fossil records can inlude the carcasses of animals and the structure of plants. These records can compare the advancements of creatures over a long period of time.

Explanation:

The further an animal or plant is burried underneath the soil, it is most likely that it lived much longer ago than a layer above it. The theory of evolution suggests that animals are always changing and adapting to their surroundings. For instance, millions of years ago, a dog like mamal existed but over time they grew accustomed to the water, developing fins flippers and eventually developed features similar to what we expect in whales today.

Plants, on the other hand, may have been much larger than the size they are today due to the excess of oxygen present in the atmosphere. Therefore, when they are fossilized scientists can realize that plants have come a long way in the tree of evolution.

Answer:

Glucose and ATP are used for energy by nearly all living things. Glucose is used to store and transport energy, and ATP is used to power life processes inside cells. Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose.

Explanation:

Most organisms use glucose and ATP for energy. ATP powers cells, and glucose stores and transports energy. Photosynthesis converts sunlight into glucose for many autotrophs.

All living things use ATP and glucose as energy sources. Energy is stored and transported by glucose, and cellular life functions are powered by ATP. Through the process of photosynthesis, which converts solar light energy into chemical energy that is stored in glucose, many autotrophs produce food.

Glycogen is the name given to this form of glucose that is stored and is composed of several linked glucose molecules. Glycogen is broken down to release glucose into the bloodstream, which is then used as fuel for the cells, when the body needs a sudden surge of energy or when the body isn't obtaining glucose from food.

citrus: thorns

mitosis: equational division

Explanation:

From the relationship:

Tendrils are thread-like appendages found in most climbing plants. They primarily function as supporting organs for climbing plants (such as cucumber) by stretching out and twinning around physical supports. The equivalence of this in citrus is the thorn.

Meiosis is a reductional cell division in which the chromosome number of the daughter cells is half of that of the other cells. Mitosis is equational division because the chromosome number of the parent cell is the same as that of daughter cells.

Transplantation involves transferring from one site to another of cells, tissues or organs, often among people. An organ transplant (eg, kidney, liver, cardiac, lung, or pancreas) from a donor may rectify organ malfunction.

The immune system remains as a standard medical treatment the greatest barrier to transplantation. An effective and intricate mechanism has been evolved in the immune system to fight off invading invaders. These systems also contribute to the refusal of the transplanted bodies that are recognized by the immune system of the receiver as foreign.

Chemical affects the Rough endoplasmic reticulum (RER)

----------------------------------------------------------------------------------------------------------

The endoplasmic reticulum is in charge of many cellular functions, such as protein folding, maturation, and transport, especially those destined for secretion. It produces the latest protein modifications after transduction.

When the synthesizing protein gets in the Rough endoplasmic reticulum,  it continues its building in the organelle. Finally, the protein suffers folding and the initial stages of glycosylation.  

Once the protein synthesis in the endoplasmic reticulum is over, these molecules are packaged into vesicles and sent to the Golgi complex for their final association with carbohydrates. Finally, protein leaves the Golgi complex and goes to its final destiny.

Any alteration in the intracellular environment

inevitably affects the organelle and its functions. When the organelle is not properly working, proteins synthesis is affected and, consequently, all the cellular activities. The affected cell homeostasis might be so altered that the cell ends dying.

If the drug affects the ER by altering its environment or directly affecting it, the organelle will fail to perform its functions, and the cell will eventually dye.

The independent and the dependent variables are the two principal factors needed in an experiment.  

 Independent variable: Refers to all the variables in an experiment that provoke a response in another variable. The independent variable changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter.

In the exposed example, the independent variable is the drug that affects the cancer cells. The researcher decides to apply it or not, and the concentrations in which the drug is.  

Dependent variable: Refers to the variable that reacts to the changes produced in the independent variable. Depending on how the independent variable is modified, the dependent variable change.  It is usually identified by the letter Y.

In the exposed example cell survival is the dependent variable. Cancer cells respond to the presence/absence of the chemical, and might differently respond to the varying concentration of the drug.

Answer:

D. Adenosine DIPHOSPHATE

Explanation:

ATP is hydrolysed to ADP in the reaction ATP+H20->ADP +Pi + energy

When Adenosine Triphosphate is used, it breaks down into Adenosine Diphosphate.

Adenosine diphosphate (ADP), also known as adenosine pyrophosphate (APP), is an important organic compound in metabolism and is essential to the flow of energy in living cells. ADP consists of three important structural components: a sugar backbone attached to adenine and two phosphate groups bonded to the 5 carbon atoms of ribose. The diphosphate group of ADP is attached to the 5’ carbon of the sugar backbone, while the adenine attaches to the 1’ carbon.

ADP can be interconverted to adenosine triphosphate (ATP) and adenosine monophosphate (AMP). ATP contains one more phosphate group than does ADP. AMP contains one fewer phosphate group. Energy transfer used by all living things is a result of the dephosphorylation of ATP by enzymes known as ATPases. The cleavage of a phosphate group from ATP results in the coupling of energy to metabolic reactions and is a by-product of ADP.ATP is continually reformed from lower-energy species ADP and AMP. The biosynthesis of ATP is achieved throughout processes such as substrate-level phosphorylation, oxidative phosphorylation, and photophosphorylation, all of which facilitate the addition of a phosphate group to ADP.

·         In an open system matter and energy can be transferred

·         In a closed system only energy can be exchanged

·         In an isolated system neither matter nor energy can be exchanged

·         The cell has to be an open system because it needs to exchange matter and energy and the only way to do so is through an open system

·         As an open system the cell allows nutrients to enter the cell and waste products to exit the cell

·         The cell does this through the use of a semi-permeable membrane

·         It needs nutrients in the forms of glucose, ions and many other molecules.

·         The nutrients can come into the cell through either passive or active transport

·         In passive transport the nutrients naturally move from a higher concentration gradient to a concentration gradient.

·         During active transport the particle need to move against the concentration gradient. To do this the cell needs energy to transport the materials. The energy comes in the form of ATP.
