Which word best describes the rock’s grain shape? jagged oval round smooth.
The word that best describes the rock's grain shape is jagged.
What do you mean by the Rock's grain shape?
It significantly defines the structural arrangement of a granular mass within a rock.
In some rocks, the grain shape results from the shapes of crystals that form the rock. While in some other rocks, the grain shape results from the fragments of other rocks that can be considered as round, smooth, and sometimes jagged.
Therefore, the word that best describes the rock's grain shape is jagged.

The base pairs in a DNA strand are held together with hydrogen bonds. If the two nitrogenous bases in each pair were held together with covalent bonds instead of hydrogen bonds, what effect would it have on the cell?
Answer:
Explanation:
Complementary base pairing is important because the hydrogen bonds between the bases hold the two strands of DNA together and because it serves as a way for DNA to replicate.
What does having multiple alleles mean? Give an example of a human multiple allele traits.
**PLEASE HELP**
Alleles are versions of a gene that will express different qualities. Multiple alleles would mean that a gene has many variations; for example, there a multiple alleles for eye color: blue, green, brown, etc. The opposite would be a gene with just two variations; an example would be simple pea plants which can have smooth or wrinkled pods.

Define symbiotic Nutrition !!!!
Answer:
Symbiotic nutrition is the relationship between organisms in which they share their nutrition and shelter. This mutual relationship may or may not be beneficial to both partners.
Explanation:
An example of a symbiotic relationship is the mutually beneficial interaction between a clownfish and an anemone. The anemone's nematocysts, or stinging cells, protect the clownfish from predators and give clownfish pairs a safe place to lay their eggs.

vacuole are fluid filled membrane bound space .there are many small vacuoles in plant cell and one large vacuole in animal cell
Answer:
vacuole stores nutrients. Nucleus control the parts of the cells
Explanation:
vacuole stores nutrients for later use, so that the cell is free from contamination.
Nucleus is the largest organelle inside the cell. It is the leader or brain who controls and commands the other organelles what to do.
If decomposers were removed
from an ecosystem, which of the
scenarios below would occur?
A. The number of plant species would increase
due to the increased space available.
B. The number of animals would decrease due to
the lack of plant life.
C. The ecosystem would collapse due to the lack
of nitrogen and carbon available to producers.
Answer:
Its either B or C but I would go with C
Explanation:
If decomposers were removed from an ecosystem the ecosystem would collapse due to the lack of nitrogen and carbon available to producers.
What are decomposers?" Decomposers are organisms, especially a soil bacterium, fungus, or invertebrate, that decomposes organic material."
Why are decomposers important for the ecosystem?Decomposers play a critical role in the flow of energy through an ecosystem:
They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.Decomposer bacteria are responsible for fixing nitrogen in the soil, meaning they transform nitrogen into a form that can be used by other organisms in the food chain.Decomposition is also important because it is part of the global carbon cycle. The carbon cycle is the cyclical movement of carbon atoms from the atmosphere to the biosphere/lithosphere and back to the atmosphere.What is an ecosystem?"An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life."
What is a producer?"Producers are autotrophs, or organisms that produce their own food. Plants and algae are examples of producers."

Why or why not ? The biology of skin color
Answer:
No
Explanation:
No skin color is perfect in ANY environment. One of the uses of melanin (A primary skin pigment) is to absorb ultraviolet rays from the sun that initiate Vit. D production.
So an abundance of melanin is beneficial in an an environment with a large amount of sun to prevent an excess of Vit. D in the blood.
Inversely, less melanin is useful to an individual in an environment that gets little sun since there is not as much melanin to inhibit Vit. D production, and thus is less likely to have a Vit. D deficiency.

which of the following?
A. Density-balanced
B. Density-dependent
C. Density-independent
Answer:
C. Density-independent
Explanation:
Limiting factors caused by natural disasters that tend to be Density-dependent. Thus, the correct option for this question is B.
What are the Limiting factors?The Limiting factors may be defined as anything that significantly constrains a population's size and declines or stops it from growing. Some examples of limiting factors may include biotic, like food, mates, and competition with other organisms for resources.
According to the context of this question, density-dependent factors are those factors that vary with respect to the density of the population. These factors affect a higher proportion of individuals when population densities are higher.
And a lower proportion when population density is lower. Examples of these factors may include, food, competition, predation, competition, parasitism, accumulation of toxic waste, etc.
Therefore, limiting factors caused by natural disasters tend to be Density-dependent. Thus, the correct option for this question is B.
