What is the impact of the microbial carrying capacity in the soil with worms?
Answer:
Effect of earthworms on soil
Earthworms need the food and habitat provided by surface residue, and they eat the fungi that become more common in no-till soils. As earthworm populations increase, they pull more and more residue into their burrows, helping to mix organic matter into the soil, improving soil structure and water infiltration.

This Venn diagram is being used to compare the characteristics of nonvascular and vascular plants.
Which characteristic is shared by the two plants, and can therefore be placed in the overlapping section?
have roots
perform photosynthesis
have xylem and phloem
produce seeds
Answer:
perform photosynthesis
The specific xylem and phloem tissues that vascular plants (tracheophytes) have for supporting and conducting water and food, respectively, set them apart from nonvascular bryophytes.Thus, option B is correct.
What best defines about nonvascular and vascular plants?The existence of chloroplasts and the green pigment chlorophyll, which enable plants to carry out photosynthesis, is the fundamental similarity between these two plant groupings. Due to their capacity to manufacture their own food, plants are now the main contributors to the ecosystem's production.
Tracheophytes are another name for vascular plants. Pteridophytes, gymnosperms, and angiosperms are among them.Nonvascular plants lack the specialized vascular system required to transmit water and nutrients. Examples of simple structures that are specialized for doing transportation are those found in algae and bryophytes.
Therefore, perform photosynthesis characteristic is shared by the two plants.

A student conducts an experiment where he places a light source below a plant. Over a three week time period he observes the plant's growth. Which of the following would he observe at the end of the three weeks.
Answer:
This question lacks options, the options are:
A). Roots would grow up out of the pot and then down towards the light.
B). The plant stem would grow up and roots would grow down.
C). The plant would start to bend over and grow downwards toward the light.
D). The plant would wilt and die.
The answer is C
Explanation:
This question is describing an experiment conducted to test the effect of LIGHT on plants movement, a phenomenon called PHOTOTROPISM. Phototropism is the response of a plant towards a light source.
According to this experiment, a light source is placed below a plant and observed over a three-week time period. At the end of three weeks, the experimenter will observe that "the plant would start to bend over and grow downwards toward the light" because the plants strictly require light to photosynthesize and grow, hence, it will respond by moving in the direction of the available light source.
The growth and the development of the plant parts towards the stimuli source are called tropism. The plant will bend downwards towards the light source.
What is phototropism?Phototropism is the phenomenon in which the parts of the organisms turns and starts growing in the direction of light sources like the sun or artificial light that acts as the external stimuli.
In the experiment, the light source acts as stimuli for the plant and the plant growth is the response. In the experiment the light source is kept down and acts as a stimulus for the plant, in return, the plant bends over and grows in the downwards direction.
Therefore, option C. plant will bend over and grow downwards.

Thinking about Mendel’s earlier studies, does the gene that determines the shape of a seed have anything to do with the seed color? (Explain your answer and name the law that supports it)
Answer:
Yes.
Explanation:
Yes, the gene that is responsible for the shape of a seed have also affect on the seed color because the dominant allele or gene appears in the shape and physical features of the offspring. Dominant allele is the gene that is responsible for the appearance of physical characteristics of an organism. Mendel's laws of inheritance are the laws which support the above phenomenon.
Yes, the gene determines the shape of a seed and seed color.
What is Phenotype?This is defined as the physical and observable trait of an organism. It is controlled by dominant and recessive allele.
When it is a dominant allele, the characteristics are visible in the organisms. Seed shape and color are physical traits which is why the answer was chosen.

what base is found in mRNA but not DNA?
Answer:
Uracil
Explanation:
DNA has the nitrogenous bases of thymine, adenine, guanine, and cytosine.
In mRNA, however, the base called uracil replaces thymine.
mRNA has the bases uracil, adenine, guanine, and cytosine.
So, uracil is the base found in mRNA and not DNA.
The base that is found in mRNA but not DNA is uracil (U) and play a unique role in the synthesis of proteins.
What are nucleotide bases?Nucleotide bases are the building blocks of DNA and RNA, which are the genetic materials of living organisms. There are four nucleotide bases in DNA: adenine (A), cytosine (C), guanine (G), and thymine (T). In RNA, thymine is replaced by uracil (U).
These nucleotide bases are arranged in a specific sequence in DNA and RNA, which provides the instructions for building proteins and performing other functions in the cell. The sequence of nucleotide bases determines the genetic information that is passed from one generation to the next.
The nucleotide bases are connected by covalent bonds to a sugar molecule and a phosphate group, forming a nucleotide. Nucleotides are joined together by covalent bonds to form a chain, which is the structure of DNA and RNA. The sequence of nucleotide bases in DNA and RNA plays a central role in the storage and expression of genetic information.
