what is living thing that work together to coexist?
Answer:
When a group of individual organisms live together in one place we call it a population. A population is defined as a group of organisms from the same species that live together in the same area.
Explanation:
Coexistence: living harmoniously with wildlife in a human-dominated world is a primer on IFAW’s mentality that coexistence is better than conflict. People’s relationship with native wildlife is often that of conflict. Animals such as coyotes, wolves, bears, and beavers are considered “nuisances” and are treated as something to be controlled. The result is millions of animals killed in barbaric ways every year by governments, all to “reduce conflict.” This report highlights examples of people finding innovative, yet simple ways to coexist with wildlife so that we can live side by side with these species. IFAW understands that not only are native wildlife species important to protect, but they are also essential to the ecosystem and therefore our own well-being. We work every day to make the planet a better place for both people and animals.

The DNA of a cell is not
programmed to coordinate the
activities needed to keep a large
cell alive. How does cell division
help the cell avoid DNA overload?
A. When a cell divides there is much less DNA
created than in the large cell, increasing the
overload.
B. Each daughter cell has its own copy of DNA
and can coordinate all the activities of a smaller
cell.
C. Cell division does not help cells to avoid DNA
overload.
Answer:
the DNA of a cell is not programmed to coordinate the activities needed to keep a. large cell alive. how does cell division help the cell a void DNA overload
The process of cell division helps the cell to avoid DNA overload by the following mechanism:
Each daughter cell has its own copy of DNA and can coordinate all the activities of a smaller cell.Thus, the correct option for this question is B.
What is Cell division?Cell division may be defined as a process through which a parent cell significantly divides into two daughter cells with an identical amount of genetic material.
DNA overload deals with the mechanism of the larger the cell, the greater the requirement for the positioning of the cell's DNA. In order to prevent this mechanism, a cell undergoes the process of division that limits the phenomena of DNA overloading.
This happens with the help of synthesizing two new daughter cells that limit the size of the parental cell.
Therefore, the correct option for this question is B.

The specific combination of alleles an organism has is called its ____ which affect(s) the organism's ____.
A. Phenotype
B. Genes
C. Genotype
D. Traits
*For the second blank it's either Genotype or Phenotype!*
The specific combination of alleles an organism has is called its genotype which affects the organism's phenotype.
What do you mean by Alleles?Alleles may be defined as one of two or more DNA sequences occurring at a particular gene locus.
Genotype may be defined as the ultimate combination of alleles of those genes which are selected for studies.
The Phenotype may be defined as the expression of a genotype in the form of a trait. It is the morphology or physiology which comes due to a combination of alleles.
Therefore, the specific combination of alleles an organism has is called its genotype which affects the organism's phenotype.

Why must the cell make sure it duplicates its
organelles and DNA before mitosis occurs?
Explanation:
Cells will duplicate or copy their DNA right before they divide. The process of cell division is called mitosis. Since the cell is dividing it needs two copies of its DNA - one is kept by the parent cell and the other is passed to the daughter cell. ... So this process of duplicating DNA is very important.

Question 12 (6 points)
Answer the following relating to PHOTOSYNTHESIS and CELLULAR RESPIRATION
for 2 points each:
1. Identify WHERE each process occurs in cells.
2. Identify what EACH process needs and makes.
3. Explain how photosynthesis AND cellular respiration are important to the carbon
cycle.
1. Photosynthesis occurs in the Chloroplast, which contain a chlorophyll whereas Cellular Respiration takes place in the double-membrane organelle called the mitochondrion.
2. PHOTOSYNTHESIS:
6CO2 + 6H2O → C6H12O6 + 6O2.
The reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll into a sugar molecule and six oxygen molecules, the products.
CELLULAR RESPIRATION :
C6H12O6 + 6O2 → 6CO2 + 6H2O.
The equation for cellular respiration is the direct opposite of photosynthesis.
3. Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.
During transcription
Answer:
mRNA is “messenger” RNA. ... The process of making mRNA from DNA is called transcription, and it occurs in the nucleus. The mRNA directs the synthesis of proteins, which occurs in the cytoplasm. mRNA formed in the nucleus is transported out of the nucleus and into the cytoplasm where it attaches to the ribosomes.
