Why do water molecules "stick together"?

Answer:

Carotenoids have two important functions in plants. First, they can contribute to photosynthesis. They do this by transferring some of the light energy they absorb to chlorophylls, which then use this energy to drive photosynthesis. Second, they can protect plants which are over-exposed to sunlight. but the letter answer I don't know

The benefit of a plant having Chlorophyll and Carotenoids is that plant can absorb energy from multiple wavelengths at once. Option A is the right answer.

Chlorophyll is the green pigment that is responsible for the green color in the leaves of plants. Carotenoid on the other hand is a yellow, orange, and red color pigment that is produced in plants, algae, and some other forms of bacteria.

the two hormones induce growth for plants

Answer:

Cohesion and adhesion draw water up the xylem. Transpiration draws water from the leaf. Negative water potential draws water into the root hairs. Cohesion and adhesion draw water up the phloem.

Answer:

A period happens because of changes in hormones in the frame. Hormones are chemical messengers. The ovaries launch the lady hormones estrogen and progesterone . those hormones motive the liner of the uterus (or womb) to build up. The constructed-up lining is prepared for a fertilized egg to connect to and begin developing. If there is no fertilized egg, the liner breaks down and bleeds. Then the identical manner occurs all once more.

It normally takes about a month for the liner to build up, then smash down. this is why a lot of ladies and women get their periods round once a month.

Answer:

10⁶

Explanation:

A 1:100 serial dilution is a dilution in which the concentration decreases 100 fold (i.e., in each dilution the concentration of the culture must be multiplied by 10⁻²). The question above indicates that a three-step 1:100 dilution was applied, which means >> 10⁻² x 10⁻² x 10⁻² = 10⁻⁶. Moreover, the dilution factor can be calculated by dividing the volume of the diluted solution by the volume of the concentrated solution. The dilution factor is the inverse of dilution, thereby in this case this value is equal to 10⁶ (dilution = 10⁻⁶ >> dilution factor = 10⁶).

[tex]$1.6 \times 10^{-3}$[/tex]

Explanation:

Given data :

Size of a typical red blood cells = 8 µm

                                                     = 0.0008 cm

The size of the largest artery through which the blood flows, known as aorta

                                                     = 20 mm

                                                     = 2 cm

Thus the number of the red blood cells that would fit side by side across the aorta would be =   2 cm x 0.0008 cm

Cloudlets, also known as altocumulus clouds, are tiny mid-level layers or patches of clouds that are most often seen as spherical clusters. Therefore, option (B) is correct.

Cloudlets, also known as altocumulus clouds, are tiny mid-level layers or patches of clouds that are most often seen as spherical clusters. However, since there are so many different types of altocumulus, they may take on a variety of forms.

Indicators of convection, or increasing heat, in the atmosphere include altocumulus clouds. Warm air rises into the sky, where it cools and condenses nearby water droplets to create the cloud formations that we see from the ground.

We are able to predict the weather with the help of satellites that monitors the movement of clouds on the earth atmosphere. Advancement of technology is the main reason which enable us to predict the weather conditions as well as the coming of cyclones in a specific region.

Answer:

Option A. Air pollution can cause water pollution.

Explanation:

Substances can permeate into the water from the air.

Water gets polluted by many causes, but a major cause is the air, and chemicals introduced can cause water pollution, hence option a and c is correct.

Water pollution is described as the contamination of water sources by chemicals that render the water unsafe for drinking, cooking, cleaning, swimming, and other uses.

Chemicals, garbage, germs, and parasites all are types of pollutants. All types of pollutants eventually end up in the water. It has the possibility of contaminating drinking water, contributing to waterborne diseases.

Water pollution has an impact on the ecosystem as well because it could induce eutrophication. This can harm fish and other aquatic organisms.

Therefore chemicals and air both pollute the water, then through into the water bodies, hence a and c is the correct option.

Answer:

a) Presencia de un catalizador

Explanation:

Los dos tipos de cambios que experimentan las sustancias en la química son cambios químicos y físicos.

Un cambio físico es un cambio es un cambio en el que la sustancia cambia en su apariencia o su forma de una manera que es reversible y en la que no se forma una nueva sustancia.

Un cambio químico es aquel en el que hay un cambio en las sustancias presentes y se forma una nueva sustancia.

La evidencia de que ha tenido lugar un cambio químico incluye

1) La formación de un precipitado a partir de la mezcla de sustancias.

2) Un cambio en el color de las sustancias.

3) Un cambio en el olfato (que desprende un olor) o en el sabor.

4) La sustancia produce luz (brilla)

5) El volumen total cambia

6) Cambio de temperatura (la mezcla se calienta o enfría)

Por lo tanto, la presencia de un catalizador, que es una sustancia que no participa en una reacción pero aumenta la velocidad de reacción, no es evidencia de una reacción química.

Human skin color is a good example of polygenic (multiple gene) inheritance. Assume that three "dominant" capital letter genes (A, B and C) control dark pigmentation because more melanin is produced. The "recessive"alleles of these three genes (a, b & c) control light pigmentation because lower amounts of melanin are produced.

Here, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

The Punnett square is a tool used to predict the probability of offspring inheriting specific alleles from their parents. If all of the offspring exhibit the same phenotype (such as purple flower color), it is likely that the parents both carried at least one dominant allele for that trait. This would mean that the purple flower color allele is dominant. Here, the parents are both purple and white, so all the offspring are dominant in nature.

Hence, from the cross of the purple and white flower, all offspring are purple, which indicates that the purple color is dominant in nature and is present in Option A.

C. The rapid twitching of the muscles generates heat.

Explanation:

When the body detects that it is cold, it will shiver in an attempt to create heat.

The rapid loosening and tightening of the muscles in this process creates heat.

This is a involuntary and natural response that helps return the body back to homeostasis and maintain a normal temperature.

So, the correct answer is C. The rapid twitching of the muscles generates heat.
