Answer:
First read the student guide to understand everything that will occur in this lab. Second read the safety guideline to ensure no one is harmed during this lab. Then gather your materials for the lab. After that section off your grass into 32 sections. Choose a quadrant and make some observations. Then choose a random sample area in your quadrant to estimate how many individual pieces of grass are present. Next, fid the average height of thegrass. Then, compare the data to quadrant #18. Plant your seeds. Count how many blades of grass are in your random sample area, and then calculate the estimated number of blades in your quadrant. Find the average height of the grass. Compare your data once again to quadrant #18, which is in the control group. Record the height of all the plants and calculate the average height for each type of plant. Compare this data with the data from quadrant # 18. Combine the data from all quadrants, and then compare the data from the experimental group to the control group. Make sure you record all your data.

Oxygen need to be supplied by the circulatory system and some of the cells also well differentiated so it can be only accept a certain processed food.
Most mollusks, or except for the some particular cephalopos like skids, have an open circulatory system in which the circulating fluid has been called hemolymph that flows through the body thanks to the muscle contractions that pump this fluid into the hemolymph vessel that discharges this fluid into the body cavity allowing substances and gases to be exchanges between body cells and the carrying hemolymph. Then this fluid goes back to the blood vessel and reinitiates the circulation.

Answer:

75% S
25% s
Explanation:
The ratio of guinea pigs in the offspring that we would predict from a Ss x ss cross is 1:1.
What is a genetic cross?
The deliberate breeding of two different individuals that results in offspring that carry part of the genetic material of each parent.
In a cross between a heterozygous dominant (Ss) guinea pig and a homozygous recessive (ss) guinea pig, the expected genotypes would be :
Ss (heterozygous dominant) :1ss (homozygous recessive) : 1S, for every guinea pig that is homozygous dominant (Ss) there will be 2 guinea pigs that are homozygous recessive (ss), resulting in the ratio of 1:1. Therefore, both the ratios will be equal. Therefore, the resulting progeny will have both the genotypic and the phenotypic ratios sames.

When an organism joins a new population, its genes become part of the new population’s gene pool. How does this gene flow affect populations?
Gene flow between populations has no effect on the gene pool.
Gene flow between populations increases genetic diversity over time.
Gene flow between populations decreases genetic diversity over time.
Gene flow increases the chance for reproductive isolation which can cause new species to form.
Answers
Answer:
B . Gene flow between populations increases genetic diversity over time.
Explanation:
Gene flow affect populations when the Gene flow between populations increases genetic diversity over time ( option B )
The effect of gene flow is to reduce genetic differences between populations, thereby preventing or delaying the evolution of the populations in different geographical areas into separate species of the pathogen.
Gene flowGene flow is the movement of genes from one population to another population. It is the introduction of genetic material from one population of a species to another, thereby changing the composition of the gene pool of the receiving population.

According to the CDC, is the flu vaccine safe and effective?
Need answer ASAP pls I’ll give brainiest
Answers
Answer:
any vaccine effectiveness can vary, recent studies show that flu vaccination reduces the risk of flu illness by between 40% and 60% among the overall population during seasons when most circulating flu viruses are well matched to the flu vaccine.
Explanation:
this is right i had to to a test and a whole lesson over this. ^^^^ that all is from my notes!
Yes, the flu vaccine is safe and effective according to the CDC.
The Centers for Disease Control and Prevention (CDC) recommends annual flu vaccination for everyone aged six months and older, with very few exceptions. The flu vaccine has been extensively studied, and the CDC and other health organizations have found it to be safe and effective in preventing flu infections and reducing the severity of illness for those who do get infected.
The flu vaccine is developed each year to protect against the most prevalent strains of the influenza virus that are expected to circulate during the upcoming flu season. It stimulates the body's immune system to produce antibodies against the virus without causing the flu itself. While the vaccine's effectiveness can vary from season to season due to changes in the circulating flu strains, it still provides significant protection and lowers the risk of severe complications and hospitalization.
As with any medical intervention, there can be some side effects, but they are usually mild and short-lived, such as soreness at the injection site or mild fever. Serious reactions to the flu vaccine are rare. The benefits of getting vaccinated far outweigh the risks, especially for high-risk groups, such as young children, older adults, pregnant women, and individuals with certain medical conditions.
Overall, the CDC and other health authorities strongly recommend flu vaccination as a safe and effective public health measure to protect individuals and communities from the flu and its potential complications. It is an essential part of flu prevention strategies and is encouraged for everyone to help reduce the spread of the virus and its impact on public health.

A. The mass of the egg white increases as the volume of the enzyme increases
B.The egg white is unaffected by the differing amounts of enzyme
C. Digestion decreases in each stomach as more of the egg whites surface area becomes exposed
D. Digestion increases as the volume of the enzyme increases
Answers
Answer:
D
Explanation:
The correct answer would be that digestion increases as the volume of the enzyme increases.
Protein digestion is catalyzed by the pepsin enzyme and aided by HCl. The combined actions of both substances form the basis for the digestion of protein in the stomach. Hence, one would expect the digestion of the boiled egg white to increase with the increase in the volume of the enzyme - all other factors remaining constant.

The plasma membrane is a boundary of cell responsible for the movement of any substance in and out of the cell, hence a is the correct option.
What is a cell membrane?All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. The cell membrane controls the flow of substances into and out of the cell.
Watery fluid surrounds and fills cells, this liquid facilitates the movement of substances across the cell membrane as well as within and outside the cell.
Some solutes (solids) can pass through cell membranes depending on their nature.
Therefore cell membrane allows the substance to pass into cell and out of the cell, hence option a is correct.
