Answers

Answer 1
100%

Wrinkled must be rr because it cannot be masked by a dominant (round) trait or it would not show. When u cross - do a punnet square they all would be Rr

what are three ways mutations can occur
I will give brainlest answer​

Answers

The three ways mutations can occur are
Mutations arise spontaneously at low frequency owing to the chemical instability of purine and pyrimidine bases and to errors during DNA replication. Natural exposure of an organism to certain environmental factors, such as ultraviolet light and chemical carcinogens (e.g., aflatoxin B1), also can cause mutations.
DNA is a long polymer of nucleotides (long strand of A,T,G,C in a defined sequences for any given gene.

The three types of mutations are 1. Substitution where a base is changed from its original to a new base (A—>G) 2 insertion where a nucleotide is added into the DNA. 3 Deletion where a nucleotide is deleted.

1 substitution 2. Insertion 3 deletion

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

Answers

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.

-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.

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

Answers

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?

Answers

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 layer

Thus, the correct answer is - due to two layers of hydrophobic tails and hydrophilic heads.

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.
