Why might it be advantageous for a sessile (non-motile) Cnidarian to have radial symmetry?
It is advantageous for a sessile (non-motile) Cnidarian to have radial symmetry. Animal body parts are radially symmetrical and they are arranged along a central axis so each part extends from the center.
Because of having radial symmetry the animal body parts can be identically cut along the central axis. Animals having radial symmetry are incapable of moving and sessile. Radial symmetry helps out to reach every corner of their body parts. Cnidarians contain two tissue layers. The outer layer is called the epidermis. The epidermis is formed from the ectoderm. The inner layer, which is called the gastrodermis, which secretes digestive juices into the inner parts called the gastrovascular cavity. This gastrodermis is formed from endoderm. Cnidarians do not have to contain mesoderm and Hence cnidarians do not have organs.

of cellular respiration?
A. an overproduction of oxygen
B. an overproduction of carbon dioxide
C. an insufficient amount of carbon dioxide
D. an insufficient amount of oxygen this
An insufficient amount of oxygen causes the body to do lactic acid fermentation instead of cellular respiration
What is lactic acid fermentation and cellular respiration ?Cellular respiration is the process by which organisms combine oxygen with food molecules, rerouting the chemical energy in these molecules into life-sustaining processes while discarding carbon dioxide and water as waste products.
Anaerobic respiration (or fermentation) of the kind that produces lactic acid uses the breakdown of carbohydrates to create ATP as a source of energy. Because it takes place without oxygen, it is called anaerobic.When there is a lack of oxygen in the cell, skeletal muscle cells use lactic acid fermentation to renew these NAD+ molecules. Because they lack the mitochondria necessary to engage in aerobic cellular respiration, red blood cells must always regenerate NAD+ via lactic acid fermentation.Learn more about Cellular respiration here:

Mia is building a diorama showing the parts of an atom. She wants to better understand the effects of electric forces. An atom is made up of particles called protons, neutrons and electrons
The way dirt sticks to surfaces in our daily lives, such as clothing and walls, is a result of electrostatic forces on fine particle adhesion.
What is the effect of electric forces?Generally, when particle material is electrically insulating, so the electric charge may be kept, electrostatic forces become significant.
Two charges interact with one another to produce electrical forces. The electric force exerted on a single charge in scenarios involving three or more charges is simply the sum of the interactions between that charge and all other charges.
Therefore, Electric force strength is influenced by the electric charge on the particles, as well as their separation from one another.

What is the active site?
A. the site on an enzyme that a substrate

B. the site on an enzyme that breaks off
C. the least important site on an enzyme
D. the site on an enzyme responsible for cell
temperature control
An active site is a site on an enzyme that a substrate binds to this. So the correct option is A.
The active site refers to the specific region of an enzyme where a substrate binds and catalysis takes place.
It is a structural element of protein that determines whether the protein is functional when undergoing a reaction from an enzyme. This structural element will be accordingly shaped to the structure of the enzyme.
A tighter fit between an active site and the substrate molecule is believed to increase the efficiency of a reaction. If the tightness between the active site of DNA polymerase and its substrate is increased, the rate of DNA replication will also increase. Most enzymes have deeply buried active sites, which can be accessed by a substrate via access channels. The active site is made up of residues that can form bonds with the substrate, particularly at the binding site.

Its green
Chlorophyll in the chloroplast reflects green color on the spectrum of
visible light.
What is chlorophyll?
The ability to produce their own nourishment exists in green plants. They achieve this through a process known as photosynthesis, which makes use of the green pigment chlorophyll. A molecule with a specific color known as a pigment can absorb light at various wavelengths depending on the color. Although there are many various kinds of pigments in nature, chlorophyll is special in that it allows plants to absorb the energy they require to develop tissues.The little structures called chloroplasts found in a plant's cells are where chlorophyll is found. This is the location of photosynthesis.Each pigment has a distinctive absorption spectrum that illustrates how it absorbs or reflects various light wavelengths. Chlorophyll and other pigments used in photosynthesis absorb wavelengths, creating electrons that power photosynthesis. All visible light wavelengths, with the exception of green, are absorbed by chlorophyll, the green pigment found in all photosynthetic cells. Because of this, plants seem green to us.
Hence, Chlorophyll in the chloroplast reflects green color on the spectrum of visible light.

which option correctly describes the mode of inheritance for sickle cell anemia
recessive, X-linked dominant, X-linked recessive Or dominant
The mode of inheritance for sickle cell anemia is recessive.
Sickle cell anemia is a type of inherited genetic disorder where the blood cells are shaped as sickle or crescent-shaped instead of being oval flat disc-shaped cells. This peculiar structure of the abnormal red blood cells deems them unable to carry sufficient oxygen to the tissues and organs of the body.
To be affected by sickle cell anemia, an individual has to inherit one copy of the sickle cell gene from each parent, irrespective of gender. Thus, it can be also called a type of autosomal recessive disease. The disease is only expressed in the homozygous recessive condition.

Which is not a way that ectothermic animals maintain their bodies at a consistent, appropriate temperature?
A. By generating large amounts of metabolic heat
B. By constricting or dilating blood vessels near the surface of the skin
C. Through behavioral adaptations such as basking in the sun or cooling in the shade
D. Bypassing cool venous blood near warm arteries running in the opposite direction
The method by which ectothermic animals do not regulate their body temperature is: (A) by generating large amount of metabolic heat.
Ectothermic animals such as snakes as well as lizards do not utilize metabolic heat in order to maintain their body temperature. Ectothermic animals are primarily dependent on the external sources of heat. The body temperature of such animals changes according to the external temperature.
On the other hand, endothermic animals tend to maintain a uniform body temperature through the process of metabolic heat production, e.g. birds as well as mammals. The internal body temperature of endothermic animals is almost independent of the temperature of their surrounding habitat.

How does the body respond if the skeletal system does not function properly? I would like a detailed answer please :)
If there is no skeletal system, the person will not be able to move at all or breathe.
Why is the skeletal system so important?The skeletal system not only serves as a support and lever for the movements of the body, it also serves as protection for the internal organs so that in the face of an impact it does not cause them any damage.
Also the thorax, apart from supporting all the thoracic organs and protecting them, will have a function in breathing so that they inflate while the diaphragm contracts. If all this is not done simultaneously, breathing will not be possible and this will be incompatible with life.
As for the skull, there will not be the correct separation of nerves and brain fluids and this will not be sustainable for life either, since a certain support is needed that gives the cerebrospinal fluid to the structures of the central nervous system and the intracranial pressure that also occurs.

Why will a decrease in light intensity result in a decrease in the rate of photosynthesis?
1. A decrease in light intensity means a decrease in the available reactants needed for photosynthesis.
2. A decrease in light intensity means the enzymes that control photosynthesis may denature.
3. A decrease in light intensity means a decrease in the energy required for photosynthesis to take place.
4. A decrease in light intensity means an increase in the energy required for photosynthesis to take place.
Answer:
3. A decrease in light intensity means a decrease in the energy required for photosynthesis to take place.
Explanation:
The greater the light intensity, the more energy supplied to the plant and therefore the faster the light-dependent stage of photosynthesis can occur.
