Which one is right??
Answer: A
Explanation:
In goats, a beard is produced by an autosomal allele that is dominant in males and recessive in females. We’ll use the symbol Bb for the beard allele and B+ for the beardless allele. Another independently assorting autosomal allele that produces a black coat (W) is dominant over the allele for a white coat (w). Give the phenotypes and their expected proportions for the cross between B+Bb Ww male × B+Bb Ww female.
Which of the following is not an option phenotype and proportion from this cross?
a. 9/16 bearded, black female
b. 3/16 bearded, black female
c. 1/16 beardless, white male
d. 3/16 bearded, white male
e. 1/16 bearded, white female
Autosomal alleles are the genetic inheritance by the variants that are passed from parent to child. From the cross between B+Bb Ww × B+Bb Ww, 3/16 bearded, black coat, and 1/16 bearded, white is not a correct phenotype. Thus, options b and e are correct.
What is a dihybrid cross?A dihybrid cross has been defined as the experimental mating of an organism that has two variable traits located at various genes. The traits can be autosomal dominant and autosomal recessive.
Given,
Autosomal dominant = Bb (beard), W (black coat)
Autosomal recessive = B+ (beardless ), w (white coat)
Parent = B+Bb Ww male and B+Bb Ww female
The cross between the parent is attached to the image below.
From the cross, it can be said that:
9/16 bearded, black coat1/16 beardless, white coat3/16 beardless, black coat3/16 bearded, white coatFrom the cross, 3/16 bearded, black females and 1/16 bearded, white females are not the phenotypes.
Therefore, options b and e. 3/16 bearded, black females and 1/16 bearded, white females are not the phenotypes.

Explanation:
It will compare that neither has an affect on the population and it will also compare that both will be equal to one another.
What is population?The term "population" refers to all citizens who are either permanently residing in a country or who are just passing through. This indicator reveals how many people typically reside in a certain area.
Growth rates are the population changes that occur each year as a result of births, deaths, and net migration.
The total population also includes national military forces deployed overseas, merchant mariners at sea, diplomatic staff based abroad, civilian foreign nationals residing in the nation, and internally displaced people residing in the nation. Demographic tools like population predictions are frequently used.
Therefore, It will compare that neither has an affect on the population and it will also compare that both will be equal to one another.

What is the function of the eukaryotic cell?
Answer: Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.
Explanation: Mark as brainllest
Answer:
their functions are different depending upon their location and organism in which they are. for example the cells of stomach wall release mucous, similarly the cell of pancreas release pancreatic juice. and the sieve tube cells help in water transfer from source to sink.

c. has no charge and is located in the nucleus
d. has a positive charge and is located in the nucleus
Answer:
d. Has a positive charge and is located in the nucleus
Memory technique:
Think of the "p" and proton and the "p" in positive.
Think of the "neu" in neutron and "neu" in neutral.
Think about electrons and electricity. Touching something "elec"tric would hurt, or give you negative feelings.
Electrons revolve around the cell while protons and neutrons are a part of the nucleus because negative and positive things would not get along.

The correct complementary DNA sequence of 3'AGGTCAGGT 5 is - D. 5' TCCAGTCCA 3'
DNA is made of two strands of DNA strands coiled together and form a ladder-like shape. DNA molecules have four nucleotide bases that joined both strands together that are Adenine (A), Guanine (G), Thymine (T), and Cytosine(C).
Each nitrogenous base has its own complementary base in a double-helical structure.The A is complimentary T and G will have CThe complementary strand is always present in an antiparallel directionIf one strand is 3' to 5' then the complementary strand would be 5' to 3'So, in the given sequence: 3'AGGTCAGGT 5

compare the hygiene allergies and asthma?
Answer:
According to the “hygiene hypothesis,” the problem with extremely clean environments is that they fail to provide the necessary exposure to germs required to “educate” the immune system so it can learn to launch its defense responses to infectious organisms. Instead, its defense responses end up being so inadequate that they actually contribute to the development of asthma.
