Answer:
Exposure to chemical or radiation.
Explanation:
Mutation in a gene can arise during meiosis due to exposure to chemical or radiation that cause change in the genes. After this change in DNA, the meiosis cell division produces gametes that can be passed to the offspring and contribute to genetic variability of the organism. Meiosis occurs in the sex cells which can be transferred from parents to offspring.

humans have one of four blood types: A,B, AB, or O. Explain what determines a persons blood type. What antigens are on the blood cells in a person withc each of these blood types? What antibodies are in the blood of a person with each of these blood types?
Answer:
if you find this helpful, Mark brainliest
Answer:
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive.
blood group A – has A antigens on the red blood cells with anti-B antibodies in the plasma.
blood group B – has B antigens with anti-A antibodies in the plasma.
blood group O – has no antigens, but both anti-A and anti-B antibodies in the plasma.
blood group AB – has both A and B antigens, but no antibodies.

A hygrometer uses hair to measure
O A. humidity
B. wind direction
O c. barometric pressure
O D. temperature
Answer: A. humidity
Explanation:
Answer:
Humidity
Explanation:
Strands of hair can relax and lengthen when the humidity increases, and then contract again when the humidity decreases. In fact, the rate of change in the length of hair strands is so dependable that they can actually be used as the basis for a hygrometer, a device that measures the humidity level in the air
In the pea garden, Mendel found that yellow seed color was dominant to green (A>a) and round seed shape was dominant to shrunken (R>r). a) What phenotypic ratio would be expected in the F2 from a cross of a pure yellow, round x green, shrunken
Answer:
The correct answer is - 9:3:3:1
Explanation:
A cross between pure yellow round seeds(AARR) to another pure green shrunken seeds (aarr). In the F1 generation, all offsprings are heterozygous yellow round(YyrRr).
Now this heterozygous self-pollination, in the F2 generation, 9 plants are Yellow round, 3 plants are yellow shrunken, 3 plants are green round and 1 plant is green wrinkled are formed.

What happens to all the weight of the food we eat? Where do the atoms in the food molecules go?
Answer:
The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change.
Explanation:
The small intestine absorbs most digested food molecules, as well as water and minerals, and passes them on to other parts of the body for storage or further chemical change.
What are the functions of small intestine?Three sections make up the small intestine: the jejunum, ileum, and duodenum. It aids in the continued digestion of stomach-derived food. It takes in water as well as vitamins, minerals, carbohydrates, fats, and proteins.
The digestion of food, absorption of body-needed nutrients, and elimination of waste are the primary functions of the small intestine.
The organ of the gastrointestinal tract known as the small intestine or small bowel is responsible for the majority of the absorption of nutrients from food. It receives bile and pancreatic juice and is located between the stomach and large intestine.

Skin Our entire body is covered with a protective layer of epithelial cells. The layer of epithelial cells acts as the first line of
defense against invaders from the exterior. Skin cells are constantly dying. Additionally, they are frequently damaged and this
could lead to gaps in the epithelial barrier. This protective layer of cells is critical to homeostasis. How does our body counter
epithelial cell death and damage to maintain homeostasis?
A
through the process of meiosis
B)
through cell replication or mitosis
by slowing down the processes of the cell cycle
D)
by producing more than 2 daughter cells per mitotic division
Answer:
B. Through cell replication or mitosis.
Explanation:
Meiosis take place only during a sexual reproduction situation (with sex cells), while mitosis is the multiplication or replicating of normal cells. The body creates and keeps balance by making up for what has been lost through adding more of it.

Results from multiple experiments suggest that the ActA protein of Listeria, an integral membrane protein expressed on the cell surface, is the only bacterial protein that is required for the movement of the bacterium within its host cell. Which combination of the following observations shows that ActA is both, necessary and sufficient for bacterial movement?
I. ActA binds to the Arp2/3 complex
II. E. Coli in which ActA is expressed moves in host cell cytosol
III. Listeria lacking the ActA gene fail to move inside the host cell cytosol.
IV. ActA has 3 transmembrane domains
V. Arp2/3, when activated, nucleates a branched actin network
a. I and II
b. II and III
c. I and III
d. III and IV
e. I and V
Answer:
b. II and III
Explanation:
The Actin assembly-inducing (ActA) protein is an integral membrane protein localized on the bacterial surface. It has been shown that ActA is necessary and sufficient to induce bacterial movement within host cells, regardless of other proteins. The function of the ActA protein for bacterial movement within host cells was discovered by identifying mutant Listeria bacteria for the gene encoding this protein which were unable to spread from cell to cell. Subsequently, by inducing mutations in other genes of the bacterial genome, researchers discovered that actA was the only protein involved in the actin assembly, which is required for cell-to-cell spread.

What is added as an anticoagulant to preserve blood specimens?
OA sodium citrate
B
sodium fluoride
O'c. potassium oxalate
OD liquid paraffin
E.
ethanol
Reset
Answer:
C. potassium oxalate for plato / edmentum
Explanation:
I took notes in the class and my notes say -
To prevent blood from clotting, toxicologists add anticoagulants to the blood sample. Anticoagulants such as potassium oxalate (30 mg/mL) is preferred over heparin or ethylenediaminetetraacetic acid (EDTA) because both heparin and EDTA interfere with the detection of certain chemicals, such as calcium, in the blood. If the blood is suspected of carbon monoxide poisoning, a layer of liquid paraffin is added over the blood sample. This layer prevents exposure to atmospheric oxygen.
