What is a coral skeletal structure that has voids between the polyps?
a.) organic structure
b.) perforated structure
c.) exhaustive structure
Answer:
A

Each polyp makes its own cup-shaped skeleton called a calyx ("KAY-lix)" from limestone (calcium carbonate). The base of the calyx is called the basal plate, and the outer walls of the calyx are called the theca ("THEE-kuh")
Answer:
I'm pretty sure it's A
Explanation:
coral skeletons are biocomposites (mineral+organics) or calcium carbonate
What two things must come together to form a seed?
Answer:
Double fertilization involves two sperm cells; one fertilizes the egg cell to form the zygote, while the other fuses with the two polar nuclei that form the endosperm. After fertilization, the fertilized ovule forms the seed while the tissues of the ovary become the fruit.

Which of the following is a disadvantage to using chlorine for disinfection of water?
Answer:
Damage our health.
Explanation:
The levels of chlorine used for disinfection of drinking water causes long-term health effects because chlorine is toxic substance that greatly damaged cells and tissues of our body. Chlorine has low protection against protozoa due to its ineffectiveness on the protozoans organisms. These protozoa also adversely affected our health so we can say that chlorine has to be used in a limit which does not harm our body.
Answer:
Chlorine reacts with organic compounds.
Explanation:
Chlorine reacts with organic matter to create chlorination byproducts which often change the overall chemical properties of water.

After mitosis and cell division are over how are the two new cells similar to the original cell in interphase??
Answer:
Explanation:
In s phase, the dna replication take place in interphase, The dna in the nucleus replicates so that each chromosome consists of two identical chromatids, then in mitosis they are pulled apart in anaphase in which both cells have half of the chromosomes, in Telophase each chromatid contains one dna molecule, which will replicate itself during interphase before the next division.
The new cells are similar from the original ones in interphase as these will have same amount of DNAs.
What is interphase?The interphase phase of the cell cycle is where the majority of the life of a typical cell occurs.
Interphase is the cell's "daily living" or metabolic phase, during which it obtains and metabolizes nutrients, grows, replicates its DNA in preparation for mitosis, and performs other "normal" cell functions.
The cell cycle's longest phase is interphase. This is the stage at which the cell grows and copies its DNA before entering mitosis.
Chromosomes align, separate, and move into new daughter cells during mitosis. Because the prefix inter- means "between," interphase occurs between mitotic (M) phases.
In interphase, the new cells are similar to the original ones because they have the same number of DNAs.
Thus, this can be the similarity between these two.

Which change is an environmental change that occurs rapidly?
forest succession
decomposition
volcanic eruption
tree growth
Answer:
Volcanic Eruption
Explanation:
(I also know because I took the quiz) The volcano is the one that rapidly changes. It can erupt any time.
Forest Succession is slower than a volcanic eruption. It might take years for the trees in a forest to grow and for the population of animals to get there. It has to be just right, it needs all the plants and animals for it to be a forest, well not all of it but most of it.
Decomposition is also slower than a volcanic eruption.
Tree growth takes a long time. It might not even be a full tree until years later. It also takes time and water.
Answer: volcanic eruption

Explanation:
What statement about the mechanism of hunger and satiety is true?
Neuropeptide Y plays a powerful role in signaling satiety.
The small intestines release the hormone cholecystokinin, which encourages us to eat.
Fat cells release leptin, which travels to the brain to signal the need to eat.
The ventromedial hypothalamus plays a role in satiety.
Answer:
The correct answer is: The ventromedial hypothalamus plays a role in satiety.
Explanation:
The hypothalamus is a part of the brain that controls many important bodily functions and connects both the nervous system with the endocrine system. The hypothalamus consists of several nuclei that have diverse functions and are located in 3 different regions.
The nucleus that plays a role in satiety is the ventromedial nucleus, terminating hunger and giving a sensation of fullness. It also plays a significant role in thermoregulation, among other things.
Neuropeptide Y, on the other hand, is a peptide that is released to make us feel hungry and encourage us to intake food (primarily carbohydrates).
Cholecystokinin is a hormone released by the small intestines after we had a meal, and its function is to improve digestion and make us feel full.
Fat cells DO release leptin, but the function of this hormone is to produce satiety, by stimulating anorexigenic (meaning they take hunger away) hormones and inhibiting orexigenic ones, like Neuropeptide Y.

Select all the correct answers. Kangaroo rats are organisms found in the desert. Deserts have a hot, dry climate. Which three adaptations must kangaroo rats possess to survive in these conditions? fewer sweat glands nocturnal behavior presence of thin coats increased water retention ability bright-colored skin
fewer sweat glands
nocturnal behavior
presence of thin coats
increased water retention ability
bright-colored skin
The three adaptations that kangaroo rats must possess to survive in a hot, dry climate are fewer sweat glands, the presence of thin coats, and increased water retention ability.
What do you mean by Adaptation?Adaptation may be defined as the accommodation of organisms to their environment in order to enhance their possibilities of survival in that environment.
Kangaroo rats must live in a hot, dry climate. They have fewer sweat glands because this prevents the loss of excessive fluids outside the body of the kangaroo.
Due to the warm and humid climate of the desert, they have better water retention capability to prevent the condition of excessive thirst.
The presence of a thin coat that is oily. They maintain this coat with hygienic dust or sand which helps them to keep the proper level of oil in the fur and prevents water loss.
Therefore, the three adaptations that kangaroo rats must possess to survive in a hot, dry climate are fewer sweat glands, the presence of thin coats, and increased water retention ability.

Please help Why must animals eat food but plants do not eat food?(1 point) Plants do not appear to eat, but they do actually eat nutrients in the soil. Animals must eat to obtain food that they can't get from the soil. Plants make their own food through photosynthesis, so they do not eat. Animals eat because the energy they make themselves is enough to live but not grow. By eating, they can grow big and strong. Plants use photosynthesis to make their own food instead of eating. Animals eat plants because they like the taste of certain fruits. Plants make their own food through photosynthesis. Animals must eat because they cannot make their own food.
Answer:
Because they will die if they don't eat food, they need the protein to keep them moving and there muscles strong. Some animals get food off of other animals.
