Answer:
Interphase is when cell grows, replacing it chromosomes while preparing for cell division.
Mitosis - copies its chromosomes and then segregates them, generating two identical nuclei.
Cytokinesis - the cytoplasm splits in half to make two new cells.
Which are ethical concerns related to editing the genes of germline cells?
Select all that apply.
The risk of unknown side effects if we allow it.
The cost of human suffering if we don’t allow it.
The effects on future generations if we allow it.
The risk that genes will not end up in future generations if we allow it.
The ethical concerns related to editing the genes of germline cells include the risk of unknown side effects and effects on future generations.
What is gene editing?Gene editing refers to the genetic engineering technologies aimed at modifying the content of genes.
Germinal gene editing assumes the edition of the germinal line and therefore it affects the gene content of future generations.
In conclusion, the ethical concerns related to editing the genes of germline cells include the risk of unknown side effects and effects on future generations.

A farmer is struggling to control the population of a certain insect on his farm. After researching population control techniques, he discovers that a particular bird is a predator of this insect. The farmer purchases a number of these birds and releases them onto his farm.
How might the farmer’s action most likely have a negative impact on the ecosystem?
The birds will increase biodiversity of native plant species.
The birds will pollinate native species, increasing genetic variation.
The birds will consume beneficial insects, as well as the pest species.
The birds will mate with native birds and create a new species.
One of the effects of the farmer's action on the ecosystem would be that the birds will consume beneficial insects along with the pest species.
Ecological effects of biological pest controlBiological control of pest requires that a living organism that will prey on the pests are introduced into the ecosystem
However, the most effective biological control of pests has to do with introducing biological agents that are very specific in action.
Using a bird species to control insect pests may lead to beneficial insects being consumed along with the insect pest in the ecosystem. The loss of beneficial insects will create a new problem in the ecosystem.

what does a stigma in a flower do?
Answer:
Part of the pistil where the pollen germinates
Explanation:
Stigma is the platform on which pollen grains land. Pollen drops on the stigma from where fertilization occurs. Stigma's main work is to basically receive the pollen, thus it has sticky surface.
Which of these is not a direct function of mitosis in humans?
O development from embryo to adult
O reproduction to produce the next generation
O repair of damaged tissue
O growth
Answer:
O reproduction to produce the next generation
Explanation:
Meiosis is responsible to reproduction (not mitosis). The rest of options are for mitosis.
The one that is not a direct function of mitosis is reproduction to produce the next generation. The correct option is B.
What is mitosis?Mitosis is a type of cell division in which one cell (the mother) divides to produce two new genetically identical cells (the daughters).
Mitosis is the process by which the DNA of the cell's nucleus is divided into two equal sets of chromosomes in the context of the cell cycle.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
Meiosis is a type of cell division that produces four gamete cells while reducing the number of chromosomes in the parent cell by half.
This process is necessary for the production of egg and sperm cells for reproduction.
Thus, the correct option is B.

2. what is the trend between 20-30 years in the kelp population? explain.
The trend between 20-30 years in the kelp population is that it is reducing due to sea urchins eating kelp and clipping the bottoms, hence, stopping kelp from regrowing.
What is the trend in the Kelp population?Kelp is a form of giant seaweed found in ocean floors.
Kelp serve as food for certain sea animals such as sea urchins.
However, due to increasing number of sea urchins and increase in environmental pressures, the Kelp population reduced in the last 20 to 30 years.
Therefore, the trend between 20-30 years in the kelp population is that it is going down due to sea urchins eating kelp and clipping the bottoms, hence, stopping kelp from regrowing.

Cell theory will not ever become the law of cells because cells undergo changes as mutations occur within them, and developing anything beyond cell theory would be impractical.
What do you mean by Cell theory?Cell theory may be defined as a theory given by M.J. Schleiden and T Schwann which states that all living organisms are made up of cells which are the smallest unit of all living entities.
It is only due to mutations, cell changes its identity and properties randomly. Hence, it seems very tough for scientists to analyze all the mutations in the cell.
