Long hair in guinea pigs is a recessive trait. A female guinea pig with long hair mates and
have all heterozygous offspring, what are the genotypes of the male?

Answers

Answer 1

Answer:

The male's genotype is homzygous short (LL)

Explanation:

This question involves a single gene coding for hair length in guinea pigs. The allele for short hair (L) is dominant over the allele for long hair (l). This means that a heterozygote will have short hair (Ll) while a guinea pig with long hair will have genotype ll.

According to this question, a female guinea pig with long hair (ll) mates and have all heterozygous offspring (Ll). This means that the male guinea pig provided only the allele for short hair (L) that made the offsprings all short. In other words, the male's genotype is LL i.e. homzygous short.

Explanation:

As a naturalist, you are responsible for training volunteers in the identification of the types of amphibians. The volunteers will use this information to correctly describe the animals to school groups that will visit your nature center. The training documentation for the volunteers lists important characteristics of the different groups of amphibians, but you notice that one of the items on the list is incorrect. Indicate which description is not correct.
A. Frogs, toads, and most salamanders have four legs whereas caecilians are legless.
B. While some frogs may advertise their distasteful nature by bright coloration, salamanders always have cryptic coloration.
C. Some adult salamanders retain larval characteristics such as external gills.
D. Most caecilians can be found burrowing in the soil of tropical forests.

Answers

Answer:

B. While some frogs may advertise their distasteful nature by bright coloration, salamanders always have cryptic coloration.

Explanation:

Amphibians are vertebrates which can live both on land and in water. they are cold-blooded and therefore, depend on warmth from sunlight to become warm and active. Their young live fully in water respire using gills. The adults have moist skins through which they respire and therefore, live in moist places or near water to keep their bodies from drying out. Many adult amphibians also have poison-producing glands in their skin to ward off predators. Poisonous amphibians usually display a warning coloration. . The species in this group include frogs, toads, salamanders, caecilians and newts.

Considering the above descriptions:

A. Frogs, toads, and most salamanders have four legs whereas caecilians are legless.

True: Caecilians are a group of limbless, wormlike or serpentine amphibians that mostly live in underground burrows or in substratum of shallow streams.

B. While some frogs may advertise their distasteful nature by bright coloration, salamanders always have cryptic coloration.

False: Some frogs such as poison frogs as well as some salamanders such as the California newt and the red eft which a brightly colored terrestrial juvenile form of the eastern newt is highly poisonous. advertise their distasteful nature by bright coloration.

C. Some adult salamanders retain larval characteristics such as external gills.

True: Some adult salamanders retain larval characteristics such as external gills. e.g. species such as the mudpuppy (Necturus maculosus) retain their gills throughout their lives.

D. Most caecilians can be found burrowing in the soil of tropical forests.

True: Caecilians are a group of limbless, wormlike or serpentine amphibians that mostly live in underground burrows or in substratum of shallow streams.

Given is a strand of DNA, fill in the corresponding RNA strand and find which amino acids that strand codes for.

Please help!

Answers

Answer:

RNA: [tex]A-U-G-U-A-U-A-C-G-G-A-U-U-G-A[/tex]

Amino acids: Methionine, Tyrosine, Threonine, Aspartic Acid

Explanation:

1) First, transcribe the DNA to RNA. For each nitrogenous base (to put it simply, the letter) listed in the DNA strand, write the strand of RNA with the matching nitrogenous base. Remember that, when transcribing, the thymine (T) from DNA can pair with adenine (A) in the RNA, adenine (A) pairs with uracil (U), and cytosine (C) and guanine (G) always pair with another.

DNA: [tex]T-A-C-A-T-A-T-G-C-C-T-A-A-C-T[/tex]

RNA: [tex]A-U-G-U-A-U-A-C-G-G-A-U-U-G-A[/tex]

2) Next, to find the amino acids the strand codes for, read the nitrogenous bases in the RNA from left to right in groups of three, or codons. Then, using a codon chart, find which amino acid the group of three bases codes for. This gives the following answer below. (Remember that the codon UGA stops the translation and therefore does not code for an amino acid.)

Amino acids: Methionine, Tyrosine, Threonine, Aspartic Acid

Amino acids: Methionine, Tyrosine, Threonine, Aspartic Acid

What are amino acids?

Amino acids are the building blocks of protein. Proteins are long chains of amino acids. Your body has thousands of different proteins that each have important jobs. Each protein has its own sequence of amino acids.

Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although hundreds of amino acids exist in nature, by far the most important are the alpha-amino acids.

The human body uses amino acids to make proteins to help the body: Break down food. Grow. Repair body tissue.

Which organism receives the least amount of energy from the producer?

a
Owl

b
Grasshopper

c
Lilypad

d
Mouse

Answers

The owl would have the least amount of energy from the producer. The higher the organism is on the food pyramid, the less energy it will receive from the producer. For example, if grass is a producer, it has the most energy. Then, if a bunny eats the grass, it takes a part of the grass’s energy but does not take all of the energy. Then, a wolf eats the bunny. The wolf gets a part of the bunny’s energy but not all. The wolf has received the least amount of energy from the grass.

Can someone please do a summary on how wind works? 7-9 sentences please I will mark brainliest!

Answers

Answer:

Wind is the movement of air. It forms when air moves from areas of high-pressure to areas of low pressure. These pressure differences are caused by temperature differences on Earth's surface. The movement is a result of different places on Earth receiving different amounts of energy from the sun. Two types of winds are global and local. Global wind systems determine weather patterns for the entire planet. Local winds are sea and land breezes that occur due to uneven absorption of solar energy.

What are the different types of leaves that plants have?

Answers

Answer:

There are two different types of leaves – simples leaves and compound leaves. The other types of leaves include acicular, linear, lanceolate, orbicular, elliptical, oblique, centric cordate, etc. They perform the function of photosynthesis and help in the removal of excess water from the aerial parts of the plant. The most obvious aspect to examine is the shape of the leaf. If it is an uninterrupted shape, it is simple. If the shape divides into smaller leaf sets the leaf is compound. Identifying plant leaves that are compound divides them into subsets.

Why is ATP like a charger battery and ADP is like an uncharged battery ?

Answers

Answer:

When a cell has no available energy, it is able to store energy by adding a phosphate group to an ADP (adenosine diphosphate) molecule. The ATP molecule that results is like a battery because both the molecule and a battery contain stored energy, while, on the other hand, ADP is a partially charged battery.
