How can I remember this definition of hybridization? (Like hints)
Vaselesa [24]
Easy. A hybrid is literally a crossing of two things. A hybrid is a blueprint (genetic instructions) ready to be build.

If you can remember the hybrid and blueprint part I'm pretty sure you'll get it.

Plants with specialized tissues that can transport fluids
Serhud [2]
The answer is vascular plants.

Vascular plants have <span>specialized tissues that can transport fluids - vascular tissue. This tissue consists of</span><span> xylem and phloem. Xylem transports water and minerals from the root to the upper parts of the plant. Phloem transports food and nutrients from the leaves, where they are produced, to the growing or storage parts of the plants. </span>

How does a cell illustrate the basic concepts of life? Be specific and use at least 3 characteristics of life.
RoseWind [281]

Answer:

Explanation:

A cell as the functional and structural unit of life exhibits numerous concepts of life which include:

1. Growth; A cell is a subject to this as the growth of a cell translates to the growth of the tissue is composed of, the cell is responsible for all biochemical actions in living organisms, this growth is achieved via mitosis.

2. Reproduction: Cells also experience reproduction via meiosis, where a diploid cell divides to produce 2haploid cells an example of this is the spermatozoa.

3. Death: Cells are also subject to death, which can either be programmed (Apoptosis), or due to sickness(Necrosis). This is also found when humans die and become stiff due to rigor mortis which occurs as a result of cell death

John and Pat are identical twins with identical DNA. John works in a movie theater, and Pat works as a lifeguard. They have very
aliya0001 [1]
John and Pat's occupation best explains the difference between their skin pigmentation. Since Pat works as a lifeguard, she is more exposed to the sun, which tans her skin. John, on the other hand, works in the theater, where he isn't exposed to sunlight that much, so he is much lighter than his twin, Pat.

In a population of white and brown rats, 16% of the population is white. if white hair is recessive to brown, what frequency of
shutvik [7]

0.36

Explanation:

For the recessive trait to show in the phenotype, the individual has to be homozygous recessive for the gene. Therefore if we designate the allele for White color as <em>r</em> and that of Brown as <em>R</em>;

<em>rr </em>= 16% = 0.16   → This is the gene frequency for recessive population

To find the allele frequency

√0.16

= 0.4

Remember the hardy Weinberg principle of allele; All allelic frequency of a gene adds up to 1 in an ideal population (that observes certain assumptions).

p + q = 1

p + 0.4 = 1

p = 1 – 0.4

p = 0.6

The allelic frequency of Brown hair is 0.6.

The frequency of individuals of a homozygous dominant genotype will be;

P² + 2pq + q² = 1

0.6 * 0.6 = 0.36
