Please i need help asap i will do 30 points it is a weather question the only thing i know is that you have to add them all up and put them to percentages like 20/80 = 25%

Answer:

Giraffes probably used to have short necks. Over time, since the branches of trees or plants were out of their reach, they adapted to this by having a longer neck. Those with longer necks are able to reach the food and eat it that those with short necks could not. Obviously, those with longer necks are able to survive and therefore reproduce. Because of reproduction, they are able to pass on this characteristic that allowed them to survive on to their offspring. This leads to offspring doing the same and over time, affecting the entire population of giraffes and soon evolving giraffes. This is natural selection doing its work in the evolution of long necks in giraffes.

Explanation:

Variation.  Organisms (within populations) exhibit individual variation in appearance and behavior.  These variations may involve body size, hair color, facial markings, voice properties, or number of offspring.  On the other hand, some traits show little to no variation among individuals—for example, number of eyes in vertebrates.

Inheritance.  Some traits are consistently passed on from parent to offspring.  Such traits are heritable, whereas other traits are strongly influenced by environmental conditions and show weak heritability.

High rate of population growth.  Most populations have more offspring each year than local resources can support leading to a struggle for resources.  Each generation experiences substantial mortality.

Answer:

A is the heart and B is the brain

Answer:

1. Metabolic wastes or excrements are substances left over from metabolic processes which cannot be used by the organism, and must therefore be excreted.

2. Organs of excretion include the skin, liver, large intestine, lungs, and kidneys.

Answer:

The child will have a 100% percent chance of a widow peak and o% chance of an straght hair.

Answer:

100%, 0%

Explanation:

When you combine the t's and T's in a Punnet Square, you get 100% of a chance of getting a widow's peak. This is because there are 2 capital Ts on one side, which combines at least 1 capital T with a lowercase t.

And, as you remember, a genotype has to have at least 1 capital for it to be a dominant one.

-jp524 :)

Answer:

the dominant get capital letters and the recessive get lowercase letters

Explanation:

Its that way because dominant is always there so it gets the big letter as to where the recessive letter gets the little letter because it really only shows if there are both recessive alleles but if there is a dominant there will always be a big letter and that dominant phenotype will always show.

Answer:

When the light wave moves from air to water, it slows down. This change in speed causes the light wave to bend. Refraction is the change in direction of a wave when it changes speed as it travels from one material to another.

Explanation:

The light wave slows down when it transitions from air to water. The light wave bends as a result of this velocity change. When a wave changes speed while moving from one substance to another, it changes direction, which is known as refraction.

Refraction is defined as a wave's shift in speed causes it to alter direction as it travels from one medium to another. Since the densities of glass and air are different, a line or spot of ink on a piece of paper will always appear to be raised when viewed through the glass slab. Due to light refraction, a coin or stone that is at the bottom of a container filled with water appears to be lifted.

A sound wave's characteristics will alter when it passes from air to water. Because crests move away from the boundary quicker than they move up to the boundary, the wave speed will increase when the wave crosses the boundary into the sea, increasing the distance between crests (the wavelength).

Thus, the light wave slows down when it transitions from air to water. The light wave bends as a result of this velocity change. When a wave changes speed while moving from one substance to another, it changes direction, which is known as refraction.

The phase of cell division that is showing here is prophase. The correct option is D.

Cell division occurs in two stages: mitosis and meiosis. When most people say "cell division," they're referring to mitosis, the process of creating new body cells.

Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.

Cell division is the process by which new cells are formed in the body for growth, repair, and replacement. This process involves the division of nuclear material as well as the division of cytoplasm.

Prophase, prometaphase, metaphase, anaphase, as well as telophase are the stages. Cytokinesis is the final physical cell division that occurs after telophase and is thus sometimes considered a sixth mitotic phase.

Prophase is the phase that is shown in the image as it involves condensing of chromatids and movement if centriole to opposite pole.

Metaphase is the phase in which the chromosomes align at the equator and anaphase separate the chromatids and move towards opposite pole.

Thus, the correct option is D.

for 12, the possiblility of the child having widows peak is 100% and the possibility of it having no widow peak 0%. For 13, The probability of the child having a widow's peak is 75%. The possibility of the child not having one is 25%. Hope this helps.

Answer: 100%, 0%, 75%, 25%

Explanation:

For 1 and 2, All of the genotypes have 1 capital which makes it widows peak 100 %, hairline 0 %. For 3 and 4, one of the genotypes have both lowercase (tt), which makes it 25 % chance of getting a straight hairline.
