Be able to explain how segmentation and exoskeletons gave some animals an adaptive advantage over those that were not segmented and did not have exoskeletons.
Answers
Answer:
Arthropods have partially alleviated this problem by having the exoskeleton form as individual plates on each body segment or individual cylinders on each segment of the appendages. The plates are called sclerites, and they are connected by flexible tissue to allow the animal to bend during movement.Early land arthropods evolved adaptations such as book lungs or trachea to breathe air. The exoskeleton was another important adaptation. It prevents an animal from drying out. It also provides support in the absence of buoyant water.
What is an example of a learned behavioral adaptation?
O camouflage
O hunting
O hibernation

Answers
Answer:
Hunting
Explanation:
Camouflage is a hereditary physical aspect, whereas hibernation and migration are instinctual. Hunting is a learned behavior as it is not as ingrained as the other two and is not automatically done.

A student keeps an onion bulb in a jar filled with water and observes that the roots continue to grow in length. The student cuts a root tip and observes it under a microscope. The image shows the observations. Which option supports the reason for an increase in the root’s length?The root cells undergo meiosis to expand and increase in length.
The root cells undergo mitosis to combine together to make the root grow.
The root cells undergo mitosis to form new identical cells.
The root cells undergo meiosis to form different types of cells.
Answers
Answer:
The root cells undergo mitosis to form new identical cells.
Explanation:
Mitosis is the process of cell division, where a cell divides into two equal cells with the same number of chromosomes. These new cells are used to promote the growth of a biological structure, promoting an elongation, a replacement, a concert, or an increase in volume. This can be seen in the case of the growth of the tip of the onion root, where the cells underwent mitosis, forming equal cells, to promote the growth of a new tip.
Why should you not exercise right after a meal? Select all that Apply

Answers
Answer:
(b) The body cannot supply enough blood to both the digestive system and muscles. (d) the arteries to the leg are open wide.
Explanation:
You shouldn't exercise right after eating a large meal, as you may feel bloating or muscle cramping. It's better to eat low-fiber, low-fat, and high-carbohydrate snacks 30 to 45 minutes before exercising. This can include yogurt, fruit, granola, peanut butter, or whole-wheat toast.
What is the major cause of changes in gene expression?
Answers
Genes encode proteins and proteins dictate cell function. Therefore, the thousands of genes expressed in a particular cell determine what that cell can do. Moreover, each step in the flow of information from DNA to RNA to protein provides the cell with a potential control point for self-regulating its functions by adjusting the amount and type of proteins it manufactures.

How is carbon moving between the air and found it decreasing

Answer:
Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned.
The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.
Explain how a concentration gradient, a membrane protein, and hydrogen ions work together to provide a mithochondrion with energy.
Answers
Answer:
Mitochondria within the electronic transport chain, are responsible for producing the energy that the cell needs, adjusting its operation to meet the metabolic needs of the body.The mitochondrion is the place where oxygen is consumed from aerobic organisms through various electron carriers and proton translocators (H +).
Explanation:
The lipid matrix of the membrane provides an impermeable barrier to ion translocation, as well as a topological organization to the catalysts in the membrane matrix that allows them to transport both e- and ions within and across the membrane in vector form. The transformation of oxidative energy into other forms of energy is carried out, initially, by generating a transmembrane electrochemical potential difference of H + ions (protomotive force). This force is the product of the asymmetric distribution of H + on both sides of the membrane, as those are translocated through it by the enzymatic complexes of the respiratory chain.The protomotive force is made up of two closely related components: one, function of the difference in chemical concentration of hydrogens across the membrane (a pH gradient) and another, dependent on the difference in electrical charge of H + ions on both sides of it (an electrical potential gradient). Gradients of electrical charge and chemical potential produce a field in which a force is exerted that tends to attract previously expelled protons into the mitochondria. It is the enzymatic complex of ATPase, the means by which the thermodynamically reversible translocation of H + ions is catalyzed. At the same time, the chemical activity of the H + on both sides of the membrane causes a change in the equilibrium constant of the enzyme, inducing it to catalyze the synthesis of ATP.

Answer:
Its A skin and anus
(just did test)
Explanation:
The skin and the Anus are sites where waste products are released from the body but not where they are produced.
Which process of the human body eliminates the waste products?Excretion is the biological process through which any unwanted or waste products are eliminated from the body.
Large and small intestines produce waste products that are not completely digested by the stomach. The liver and kidney are also the sites of waste products like the removal of carbon dioxide and synthesis of urine respectively.
Therefore, the skin and the Anus are sites where waste products are released from the body but not where they are produced.

A cell has undergone determination to become an epithelial lung cell. If it is transplanted to a leg muscle, what do you think will happen to this cell?
Answers
Answer:
Change occur in form and structure of the cell.
Explanation:
The structure and shape of the cell change because the function of leg is different from the lungs. In the lungs the epithelial lung cell is responsible for the detection and protection of the cells against pathogen while on the other hand, the leg has the function to move an individual from one place to another so due to difference in function, the cells of both regions have different shape and structure of the cell and the epithelial lung cell will be changed into a leg muscle cell.
Because all of the cells in a multi-cellular organism come from a single cell, all of its cells will have the same number of
Answers
Answer:
Chromosomes
Explanation:
Multicellular organism are organisms that have more than one cells in their body. However, from the very beginning of every living organism including multicellular organisms, only ONE cell is required. In the case of multicellular organisms, this one cell undergoes division by mitosis to form other cells.
Since the cells divide by mitosis i.e 1 forms 2, 2 forms 4 etc.,. each of the cells are genetically identical to one another. Hence, this means that all the cells will contain the same number of chromosomes in their genome. For example, a dog as a multicellular organism has cells that emanate from one cell. If that one cell contain 39 chromosomes, all cells in the dog will also contain 39 chromosomes.

A dam is built across a river to generate electricity. What is likely effect of the construction of a dam on the river?
a)increase in the size of fish in the river
b)increase in the water flow in the river
c)decrease in the population of aquatic organisms in the river
d)decrease in the amount of pollutants dumped into the river
Answers
Answer:
c i think
Explanation:
Most likely the effect of the construction of a dam on the river is that it decreases the population of aquatic organisms in the river. Thus, the correct option is C.
What is Population?A Population may be defined as the group of individuals significantly belonging to the same species living in the same area in a definite time period.
When a dam is built across a river in order to generate electricity, it results in the reduction of the population of aquatic organisms in the river.
This is because the whole construction affects the natural habitat of aquatic organisms as well as their adaptations. So, such populations are frightened due to external construction and do not play their essential roles.
Therefore, most likely the effect of the construction of a dam on the river is that it decreases the population of aquatic organisms in the river. Thus, the correct option is C.
