Answer: c. produce hormones that help regulate many body functions
Explanation:
The endocrine system helps in the release of hormones and regulating them into bloodstream and these hormones that are released then travel to the cells to perform different functions like growth and development, reproduction, controlling of ones mood, metabolism etc.
Therefore, the correct option is C "produce hormones that help regulate many body functions"
the failure of homologous chromosomes to separate correctly during meiosis is called
Answer:
Aneuploidy is caused by nondisjunction
Explanation:
Aneuploidy is caused by nondisjunction, which occurs when pairs of homologous chromosomes or sister chromatids fail to separate during meiosis. The loss of a single chromosome from a diploid genome is called monosomy (2n-1), while the gain of one chromosome is called trisomy (2n+1).
Explanation:
Nondisjunction in Meiosis : Nondisjunction occurs when homologous chromosomes fail to separate during meiosis, resulting in an abnormal chromosome number

Answer:
C!!
Explanation:
It's not B because it's located in the great plains. Not D because in 50 years, 70% of the aquifer will be gone. Not A because water use isn't regulated.
Ogallala Aquifer is the rock holding the groundwater in the Great Plains of America. The Ogallala Aquifer is running out of water. Thus, option C is correct.
What is Ogallala Aquifer?Ogallala Aquifer is an underground layer of water that is held by the rocks, pebbles, and gravel that make the water well above the surface. It is not beneath the East Coast but is situated on the Great Plains of the United States.
It has been reported that the water usage of the Ogallala Aquifer is not regulated and hence it does not have enough water to last up to 6,000 years. At approx 70%, the water of the aquifer will be soon gone resulting in the deprivation of the water.
Therefore, option C. the Ogallala Aquifer is running out of water is correct.

Where do the thickest deposits of terrigenous sediment typically form?
A. deep-ocean trenches, such as the Mariana Trench
B. mid-ocean ridges
C. abyssal plains
D. continental margins near the mouths of rivers
Answer: D. continental margins near the mouths of rivers
Explanation:
Terrigenous sediments are those that are formed via processes on land as opposed to in water. They result mostly from the erosion of rocks and yet make up 20% of all ocean sediments.
Continental margins near the mouths of rivers contain the thickest deposits of this sediments as they are closest to land which is the source. It is made more convenient by the presence of rivers bringing the sediments to them when the rocks are eroded.
Why are phospholipids of the plasma membrane oriented such that their heads are at the membrane surfaces and their tails are buried in the interior of the membrane?
Answer:
The plasma membrane is semi-permeable. The reason for this is because of the orientation of the phospholipids. The heads at the surface are hydrophilic so they face the water. The tails are hydrophobic so they face away from the water.
Explanation:
The phospholipids of the plasma membrane are oriented such that their heads are at the membrane surfaces and their tails are buried in the interior of the membrane - due to the fact that phospholipids have hydrophobic tails and hydrophilic heads.
Phospholipids consist of fatty acids and alcohol in the plasma membrane are arranged in two layers, known as the phospholipid bilayer. It has a hydrophobic or water-hating tail and a hydrophilic or water-loving head.
it has a head and two tails.As the tails are hydrophobic so, face the inside, away from the water.As the heads are hydrophilic so face outwardHeads are towards intracellular and extracellular fluid.Tails are meet the inner layerThus, the correct answer is - due to two layers of hydrophobic tails and hydrophilic heads.

Why did you not see any chloroplasts in the onion epidermal cells, unlike in the Elodea (Anacharis) cells?
-Chloroplasts in onion cells are hidden by the large central vacuole.
-The part of the onion viewed under the microscope grows underground.
-The purpose of chloroplasts is to make the plant green but onions are not green.
-Chloroplasts are organelles that absorb sunlight energy and perform photosynthesis.
-Plant parts that grow underground are not exposed to sunlight.
-Onions had chloroplasts before they were picked from the ground but the chloroplasts dried up and disappeared after being exposed to the sunlight.
-Onions are not plants and therefore do not have chloroplasts.
-Plant parts that are not exposed to sunlight cannot do photosynthesis.

What are two ways selective breeding is helpful in agriculture? A. It can take many generations to get desired traits. B. It can cause animals to inherit two recessive alleles C. It can produce crops that are resistant to pests. D. It can result in animals that can produce more food.
The two ways in which selective breeding is helpful are that it can produce crops that are resistant to pests and animals that can produce more food; these are options C and D.
What is the importance of selective breeding?Selective breeding produces plants and animals that are genetically modified to have a specific trait, such as animals being modified to produce higher-quality milk and meat or plants being modified to produce pest-resistant foods. This type of breeding and its resultant product are different from the wild type, and generally, these products are made for the commercial purpose of feeding a large population.
Hence, the two ways in which selective breeding is helpful are that it can produce crops that are resistant to pests and animals that can produce more food; these are options C and D.

Answer:

A scientist is researching two different traits in an insect: body texture and color. Smooth body (B) is dominant to bumpy body (b), and gray (G) is dominant to white (g). A BbGg and a bbgg insect mate and produce the following 480 offspring: Phenotype Number of Offspring Smooth, gray 119 Bumpy, white 117 Smooth, white 123 Bumpy, gray 121 What type of inheritance is displayed from these offspring
Answer:
Independent assortment
Explanation:
The type of inheritance displayed by the offspring is a simple independent assortment inheritance according to Mendelian law.
The result of crossing BbGg and bbgg is as follows (see the attached image)
4 BbGg smooth and gray
4 Bbgg smooth and white
4 bbGg bumpy and gray
4 bbgg bumpy and white
The phenotype ratio from the cross is 1:1:1:1 as far as the independent assortment is concerned.
Now, looking at the population of each phenotype from the cross
Smooth, gray 119
Smooth, white 123
Bumpy, gray 121
Bumpy, white 117
119:123:121:117 is approximately equal to 1:1:1:1.
Hence, the cross agrees with Mendel's law of independent assortment of genes.
