Answers
Answer:
earthworm taking soil for nutrition
Explanation:
it's consuming the energy unlike the rock
An earthworm taking in soil for nutrition is another example of an open system, option B is correct.
An open system is characterized by its ability to exchange matter and energy with its external environment. In the case of an earthworm, it actively takes in soil for nutrition, breaking down organic matter and absorbing nutrients through its digestive system. This process allows the earthworm to grow, reproduce, and carry out essential life functions.
The exchange of soil, nutrients, and gases (such as oxygen) occurs continuously, sustaining the earthworm's biological activities. In contrast, a rock in a field does not interact with its environment in the same way. It remains a closed system, passively experiencing natural forces without actively receiving external inputs or engaging in metabolic processes, option B is correct.

Is biodiversity renewable or nonrenewable?
Answers
Answer:
renewable
Explanation:
Biodiversity refers to the variety of plant and animal wild life in the world or in a particular habitat which is important in that specific location. Renewable is anything that recycles itself through its consumption. Which is what happens in biomes. Life dies off and provides the necessary resources for new life to be reborn and so on, thus making Biodiversity renewable.
there are at least 2 million species on earth, and species have been naturally evolving and going extinct for billions of years (in fact, over 99% of all species that ever existed are now extinct!). given these facts, why do we care if human activity is driving other species extinct as we grow?
Answers
Answer:
This is because humans are causing species to go extinct at a faster rate than the normal rate.
Explanation:
It is documented that there are at least 2 million species on earth, and species have been naturally evolving and going extinct for billions of years. Some may say even if nothing is done there would still be extinction of this species which is true.
We care if human activity is driving other species extinct as we grow because humans are causing species to go extinct at a faster rate than the normal rate.

Answers
An example of quantitative data is mothers and their infants typically nap for two to three hours each afternoon. Therefore, option A is correct.
What is quantitative data ?The data expressing a certain quantity and amount or range is called as quantitative data. The two main types of quantitative data are discrete data and continuous data.
The difference between the qualitative data and quantitative data is the quantitative data is numbers-based, countable, or measurable while qualitative data is interpretation-based, descriptive, and relating to language.

One difference between plant and animal cells is that (1) plant cells have cell walls; animal cells don't (2) plant cells can't move; animal cells can (3) plant cells live in water; animal cells don't ( 4) plant cells have a nucleus; animal cells don't (5) plant cells have vacuoles; animal cells don't
Answers
Answer:
1) Plants cells have cell walls; animal cells don’t.
Explanation:
Cell walls function is to help cells stick to each other, which is good for plants since they don’t move around. But as for animal, they need to move around so it’s not good for them to have it.
Without cell walls, animal cells can take on different shapes!
It makes it able to move easier, flexible.

When a true-breeding blue salamander is mated to a true-breeding red salamander, 100%of the offspring are blue. Assuming that salamander skin color is determined by a singlegene, which of the following statements are correct?A. The blue allele is dominant to the red alleleB. The red allele is recessive to the blue alleleC. The blue gene is dominant to the red geneD. The red gene is recessive to the blue geneE. Both A and BF. Both C and D
Answers
Answer:
Both A and B
Explanation:
True breed is a breed that is 100% identical with the parent, the traits inherited from that parents are 100% controlled by same allele of a gene hence they are exact copy.
A single gene can have several alleles, it is the allele that combines together that determines what is seen or expressed.
Allele for blue colour is dominant over allele for red color and that is what led to the phenotypic appearance of the offspring which is blue and the red color is masked. Also, because they are true breeds it means the genotype have the same allele e.g. AA

How do the hypothesis of microspheres and the RNA World hypothesis build off of each other?
Answers
Answer:
Microspheres are formed of proteins. It has been found that when an amino acid is permitted to get desiccated, then this amino acid produces proteins that in turn give rise to microspheres.
On the basis of the RNA world hypothesis, the first genetic substance was considered to be an RNA, and then later the DNA turned out to be the genetic substance of higher species during the passage of evolution. It was also believed that microspheres comprised encoded information within it, and at the time of the splitting of microspheres, this encrypted information may have got transferred to the upcoming generation.

C. Mitosis
D. Replication
Answers
Answer:
A.
Explanation:
osmosis and diffusion are both passive transport bc it doesnt require energy and only moves down cocentration gradient, never against concertration gradient. Give me a brainliest if i helped! ♡
When certain molecules may move by osmosis or diffusion through the membrane without the cell using any energy, the process is called passive transport.
When diffusion takes place between compartments separated by a membrane permeable to that solute, it is called simple diffusion.
Passive transport does not require any additional energy other than the movement of the molecules, moving these in favor of their concentration gradient.
In other words, simple diffusion does not require ATP expenditure, since it is a spontaneous phenomenon.
The molecules that are mobilized by simple diffusion through the membrane are the nonpolar and small, the fat-soluble and the small polar ones, but without a net electric charge, such as H2O.
In the particular case of H2O, passive transport is called osmosis, the passage of water through the membrane by osmosis always takes place spontaneously and very quickly.
H2O will diffuse from the compartment with the lowest concentration of solutes or hypotonic medium, to the compartment with the highest concentration of solutes or hypertonic medium, in such a way as to equalize the concentrations in both compartments.
Therefore, we can conclude that when certain molecules may move by osmosis or diffusion through the membrane without the cell using any energy, the process is called passive transport.
