On your whiteboard, and without the help of your textbook or the internet, sketch what a cell looks like. Draw whatever you can remember about a cell and label it.
Answers
To draw a cell we have to consider that they are formed by different organelles and structures. Between plant and animals cells those structures share similitudes and differences in terms of whether they are present or not. One of the main differences between these two kinds of cells is the cell wall present in plant cells, and the absence in animal cells, which gives a rigid aspect to the former ones, with respect to the latter.
We can notice that there are evident differences, like the presence of centrioles in animal cells, and the presence of chloroplast in plant cells. In plants, we can also find large vacuoles than in animal cells.

How does slow movement aid sloths in acquiring food?
Answers
Sloths are so slow moving that algae is able to grow symbiotically in their fur. This algae can be licked out of the sloth's fur to provide it with nourishment.
Answer:
Slow movement helps sloths to acquire food in several ways. Sloths are herbivores that spend most of their time in trees and have a slow metabolism that enables them to survive on a low-energy diet. Their slow movements also help them to conserve energy, which is necessary for them to survive in their natural habitat.The slow movements of sloths also help them to avoid predators, such as jaguars and eagles, that are known to prey on them. By moving slowly, sloths can avoid detection by these predators and remain hidden in the trees where they live.
Sloths have long arms and legs with curved claws that are adapted to their arboreal lifestyle. These claws allow them to hang upside down from branches and move through the trees with ease. Sloths are also able to rotate their heads up to 270 degrees, which allows them to scan their surroundings for potential predators and food sources.
The slow movements of sloths are also beneficial when it comes to acquiring food. Sloths feed mainly on leaves, which are high in fiber but low in nutrients. By moving slowly, sloths are able to conserve energy and digest their food more efficiently. Sloths also have a specialized digestive system that allows them to extract more nutrients from their food than other herbivores.
In conclusion, slow movements aid sloths in acquiring food by helping them conserve energy, avoid predators, and digest their food more efficiently. Their long arms and legs with curved claws, and their ability to rotate their heads up to 270 degrees, also make it easier for them to move through the trees and find food sources.

A substance that controls the expression of genes is known as an inducer in molecular biology. An inducer works in two different ways, namely:
1. By turning off the repressors. An inducer binds to the repressor, which causes the gene to be expressed. The repressor cannot bind to the operator because of the inducer's binding to the repressor. The transcription of operon genes can then start by RNA polymerase.
2. By attracting activators. Absent an inducer, activators often bind activator DNA sequences weakly. The complex formed by the binding of the activator and inducer to the activation sequence activates the target gene. Transcription is halted by removing the inducer.

In eukaryotes, the components of citric acid cycling and the electron transport chain are located in the ____.
Answers
In eukaryotes, the components of citric acid cycling and the electron transport chain are located in the inner mitochondrial membrane.
Glycolysis, the citric acid cycle and the electron transport chain are the three stages of cellular respiration through which a cell produces ATP.
In the process of cellular respiration, glucose that is derived from food and oxygen is used to produce carbon dioxide and water along with the release of energy in the form of ATP.
The process of glycolysis for a cell happens in the cytoplasm of a cell. The process of citric acid cycle as well as the electron transport chain occurs in the mitochondria. Hence, the components for both these cycles will be present in the inner mitochondrial membrane.

Reabsorption of fluid into the capillary takes place at the arterial end or venous end of the capillary?.
Answers
The venous end of the capillary is where reabsorption of fluid into the capillary takes place.
Osmotic pressure is the net force that propels reabsorption—the flow of fluid from the interstitial fluid back into the capillaries—into the body (sometimes referred to as oncotic pressure).
The blood's hydrostatic pressure is the reason behind this (which favors filtration out of the capillary is lowest in the venous end of the capillary.) Cationic Exchange Because capillary hydrostatic pressure (CHP) exceeds blood colloidal osmotic pressure, net filtration occurs close to the arterial end of the capillary (BCOP).
Due to the fact that CHP = BCOP, there is no net fluid movement around the middle. Near the venous end, net reabsorption takes place because BCOP is higher than CHP.

Fluoroacetate occurs naturally in some plants and is highly toxic to mammals and insects. In cells, it is converted to fluorocitrate, which binds tightly and inhibits an enzyme crucial for cellular respiration, causing citrate buildup. To what enzyme does fluorocitrate bind?.
Answers
It is changed into fluorocitrate inside of cells. which forms citrate due to its strong binding and inhibition of an enzyme necessary for cellular respiration.
Citrate synthase changes fluoroacetate into fluorocitrate after oral dosing and intestinal absorption.
Because fluoroacetate is chemically identical to acetate, which plays a crucial function in cellular metabolism, it is extremely poisonous to mammals and insects.
By blocking the Krebs cycle, fluoroacetate has hazardous effects (after being converted to fluorocitrate). Fluoroacetyl coenzyme A, which condenses with oxaloacetate to generate fluorocitrate, incorporates the chemical.
"Trojan horse inhibitor" has been used to describe fluoroacetate. It enters the citric acid cycle and is changed by the enzyme acetyl-CoA-synthetase into fluoroacetyl-CoA, which is then changed into fluorocitrate by the enzyme citrate synthase. Before it interacts with aconitase and stops the citric acid cycle, it is not inhibitory.

Plant tissue systems can be classified as either permanent (or non-meristematic) tissue or meristematic tissue. Animal stem cells are analogous to meristematic tissue in that both types of cells continue to divide undifferentiated and aid in the growth of the plant. Plant cells that are no longer actively dividing make up permanent tissue in contrast.
Cells produced by meristems rapidly differentiate, or specialize, and develop into permanent tissue. These cells adopt a defined function and stop proliferating. Dermal, vascular, and ground tissue are the three primary tissue types that discriminate between them. All three tissue types are present in each plant organ (leaves, stems, and roots):
