Two parent plants are crossed. The phenotypes of 1,000 offspring plants are shown below. What are the most likely genotypes of the parent plants?
A. ANL/ANL, YGR/YGR for parent 1, and anl/anl, ygr/ygr for parent 2.
B. ANL/anl, YGR/ygr for parent 1, and ANL/anl, YGR/ygr for parent 2.
C. ANL/anl, YGR/ygr for parent 1, and anl/anl, ygr/ygr for parent 2.
D. anl/anl, YGR/ygr for parent 1, and anl/anl, YGR/ygr for parent 2.
Answer:
C
Explanation:
The data shows that each phenotype occurs about one-fourth of the time. That means that there are about equal numbers of purple-stemmed and green-stemmed plants, and about equal numbers of green-leaf and yellow-leaf plants. Of the four choices, answer A can be eliminated because all of the offspring of an ANL/ANL plant will have purple stems. Answer D can be eliminated because all of the offspring of two anl/anl parents will have green stems.

How are rivers made ?
Answer:
Rivers usually begin in upland areas, when rain falls on high ground and begins to flow downhill. They always flow downhill because of gravity. They then flow across the land - meandering - or going around objects such as hills or large rocks.
Explanation:
Hope this helps!
Answer:
A river is created when water moves from higher elevation to lower elevation. It usually goes downhill, and can join with other rivers. The river ends when it flows into an ocean.

viruses and prions
rickettsia and viruses
viruses and bacteria
rickettsia and prions
Answer:
rickettsia and viruses
Explanation:
This is because obligate intracellular parasite are parasite that affect humans and they grow, reproduce and survive inside the host cell. These parasite cannot live or survive outside host cell but they live inside host cell, replicate and they depend on the host cell resources i.e the use host cell resources thereby causing harm on the host cell. rickettsia and viruses are parasite that can only survive inside a living organism.

In pea plants, yellow seeds are dominant over green seeds. What would be the
expected genotypic ratio in a cross between a plant with green seeds & a plant that
is heterozygous for yellow seed color?
A. 1:1
B. 1:3
C. 1:2:1
D. 4:1
The expected genotype ratio is 1:3.
The genotype of an organism is the sum total of the gens that the organism received from its parents. The genotype determines the traits of an organism (phenotype).
Let the dominant gene be R and the recessive gene be r then we have a cross between RR and Rr. The expected genotype ratio is 1:3.

Describe how the process of apoptosis occurs?
Answer:
Apoptosis is an orderly process in which the cell's contents break down and are packaged into small packets of membrane for “garbage collection” by immune cells. It contrasts with necrosis (death by injury), in which the dying cell's contents spill out and cause inflammation. Apoptosis removes cells during development.
Apoptosis is a form of programmed cell death that occurs in multicellular organisms.
What is apoptosis ?It is a natural biological process of programmed cell death in which the cells destroy themselves and maintain the smooth function of the body parts.
There are two types cell death such as Programmed death of cells or apoptosis and uncontrolled death or Necrosis.
Apoptosis can occur via two pathway such as Extrinsic Pathway is triggered in response to external stimuli, ligand binding at death receptor and these receptors are called as Tumor Necrosis Factor gene.
Intrinsic Pathway triggered in response to internal stimuli such as biochemical stress, DNA damage and this pathway is modulated Bax, and Bcl-2 molecules.
Apoptosis helps in maintaining homeostasis, proper size of the body, cell number, elimination of unwanted cell, T-lymphocytes etc.

Which is true of the material that
makes up wires?
A. Wires made of conductors have high
resistance.
B. Wires made of conductors have greater
resistance.
C. Wires made of conductors have low
resistance.
Wires made of conductors have low resistance. The correct option is C.
What is a conductor?Conductors are materials that allow the flow of through them. Insulators are those materials that prevent electricity from passing through them.
Copper, aluminum, gold, and silver are a few examples of common conductors. Wood, rubber, plastic, and glass are a few typical insulators.
A conductor is an object or kind of material that permits the movement of charge (electric current) in one or more directions.
This term is used in both physics and electrical engineering. Metal-based materials are frequently used as electrical conductors.
Low resistance to the flow of electricity is provided by good conductors like copper, aluminum, etc. They do so because they have a lot of free electrons.
There are no free electrons in insulators. As a result, despite applying voltage across them, essentially no electric current flows through them.
Thus, the correct option is C.

How does hair help prevent diseases?
Hair plays an important role in our lives. The hair on our head keeps us warm and acts as a cushion for our skull. Hair appearance can also help form our identity and self-image, which makes hair loss very troubling.
Most hair disorders aren’t serious, but they are often considered major cosmetic issues that require treatment. Androgenetic alopecia is the most common form of hair loss, although there are a number of other hair conditions that can affect the scalp and other parts of the body.
Black coat is dominant over white coat in guinea pigs. A homo-zygous black pig is mated with another homo-zygous black pig.
What are the genotypes of the parents?
Question 5 options:
bb and bb
BB and bb
Bb and Bb
BB and BB
Answer:
BB and BB
Explanation:
BB is a homo-zygous allele and both of the parent guinea pigs are homo-zygous.
A black coat is dominant over a white coat in guinea pigs. The genotypes of the parents are BB and BB. The correct option is d.
What is a genotype?The terms genotype and phenotype relate to the individual's alleles and the observable traits that are generated from the genotype and determined by the dominance of the alleles, respectively.
For black coat = B
For White coat = b
A homozygous black pig is mated with another homozygous black pig. Homozygous means only one character will be shown in the genotype, that is the dominant and the dominant trait is black, B so, the genotype will be BB and BB. Recessive traits are hidden that do not show, and that is also black.
Therefore, the correct option is d. BB and BB.
