Which of the following changes takes place during the third trimester of a womans pregnancy
A.) the fetus begins to form teeth
B.) the fetus develops toenails,lips, and eyelashes
C.)The mothers uterine contractions begin
D.) the fetus’s hands and feet appear
Answer:D
Explanation:
The fetus develops toenails, lips, and eyelashes is the change that takes place during the third trimester of a woman's pregnancy. Therefore, option (B) is correct.
What happens in third trimester?By the third trimester, which begins around the 28th week of pregnancy and lasts until birth, the fetus has already formed most of its organs and body parts. During this stage of pregnancy, the fetus undergoes significant growth and development. This includes the development of toenails, lips, and eyelashes. Additionally, the fetus begins to accumulate body fat, and its brain undergoes rapid development.
To answer the other options, the formation of teeth begins during the embryonic stage, which occurs in the first trimester. The mother's uterine contractions typically do not begin until labor, which occurs at the end of the third trimester or later. The fetus's hands and feet appear during the embryonic stage, specifically around the 6th week of pregnancy.

Water is attracted to the sides of a glass cylinder is an example of cohesion.
What do you mean by cohesion?Cohesion means sticking together. If your group of friends heads to the lunchroom as a team and sits all together, you're demonstrating strong cohesion.
Cohesion allows for the development of surface tension, the capacity of a substance to withstand being ruptured when placed under tension or stress.
Cohesion refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another.

How does the tRNA-mRNA interaction ensure that the amino acids are added in the correct order?
Answer:
Only the tRNA carrying the next amino acid in the polypeptide chain has the anticodon that binds to the appropriate location on the mRNA.
This system ensures that amino acids are added to the chain in the correct order. At the beginning of translation, the ribosome and a tRNA attach to the mRNA.

Landforms are created through destructive forces such as weathering. Which of these is an example of physical weathering? A acid rain. B abrasion. C hydrolysis. D oxidation
Answer: C. HYDROLYSIS
Explenation: Chemical weathering occurs when water dissolves minerals in a rock, producing new compounds. This reaction is called hydrolysis. Hydrolysis occurs, for example, when water comes in contact with granite.
Landforms are created through destructive forces such as weathering, so abrasion is an example of physical weathering that is in Option B as the physical weathering is a type of weathering that involves mechanical breakdown.
What is the significance of weathering in the environment?Physical weathering is caused by physical forces, such as the expansion and contraction of rock due to changes in temperature and abrasion is a specific type of physical weathering that occurs when rock or soil is rubbed against other rock or soil. In physical weathering, rock fragments or particles are carried by water, wind, or ice, and the repeated collisions and friction caused by abrasion can lead to significant changes in the shape.
Hence, landforms are created through destructive forces such as weathering, so abrasion is an example of physical weathering that is in Option B as the physical weathering is a type of weathering that involves mechanical breakdown.

match the following
(i) Stem tuber (a) minerals
(ii) Conditioned Reflex (b) Blue green algae
(iii) Blood Circulation (c) potato
(iv) Pancreas (d) chlorosis
(v) Autotrophs (e) Pavlov's Experiment
(vi) Active transport (f) Insulin
(g) William Harvey
Answer:
Stem tuber ---- Potato
Conditioned reflex ---- Pavlov's experiment
Blood circulation ---- William harvey
Pancreas ---- Insulin
Autotrophs ------ Blue green algae
Active transport ---- Minerals
Note: Chlorosis has no matching item in the list. Explanation is given below.
Explanation:
Stem tubers are plants which store their food in their stems. Potatoes are stem tubers.
Conditioned reflex is a reflex is acquired gradually by training in association with specific repeated external stimuli. For example, the Russian psychologist Ivan Pavlov's performed experiments on conditioned reflex using a dog. He demonstrated that a dog will salivate on the sound of a bell even if there is no food given to it if the ringing of the bell preceded every feeding session of the dog.
William Harvey discovered the circulation of blood and the function of the heart .
The islets of Langerhans found in the Pancreas secretes the hormone, insulin.
Autotrophs are organisms which are able to manufacture their own food, Blue green algae are examples of autotrophs.
Active transport is transport which requires expenditure of energy and occurs against the concentration gradient of the substance being transported. Because the concentration of minerals in the soil are in very low concentration, active transport is used by the root hair cells carrier proteins to move mineral ions across the membrane into the cell against the concentration gradient. ATP hydrolysis provides the energy for this process.
Chlorosis is a disease which appears as the yellowing of leaves in plants and in human a green tinging of the skin which is caused by the deficiency of minerals especially iron and manganese.

Marianne is conducting an experiment on homeostasis in paramecium which is a type of single celled organism. Which of these observation
Answer:
Contractile vacuole is responsible for maintaining the homeostasis in paramecium.
Explanation:
The observation of this experiment is that contractile vacuole is responsible for maintaining the homeostasis in paramecium because the contractile vacuole regulates the quantity of water inside a cell. Contractile vacuole controls the water balance in the body by absorbing and removing the excess amount of water out of the cell. This function of contractile vacuole allows the cells to survive under hypotonic stress that is present in the pond water or any other stressful environment.

There are 450 calories in 100 g of trail mix. If you burn 30 calories in 10 minutes of walking, how much trail mix should you eat to replenish the energy you spend walking for 2 hours?
Answer:
to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten
Explanation:
Firstly, let us calculate the number of calories burnt in 2 hours
in 10 minutes; 30 calories are burnt
∴ in 1 minute 30/10 calories are burnt = 3 calories are burnt
2 hours = 120 minute
∴ in 120 minutes 3 × 120 = 360 calories are burnt.
Next, let us calculate the amount of trail mix that contains 360 calories
100g of trail mix = 450 calories
450 calories = 100 g
1 calory = 100/450
∴ 360 calories = 360 × (100/450)
= 360 × 0.222 = 80g
∴ to replenish the energy spent walking for 2 hours, 80g of trail mix should be eaten

In pea plants, yellow pea color (Y) is dominant over green pea color (y).
What would the phenotype be if the genotype is Yy.
Answer:
So we know that yellow pea is dominant over green pea
then offspring might be 75% yellow pea and 25% green pea. Since yellow pea is dominant I feel like it will still be Y because its dominant
