I do think that they close to not allow too much of either water or air from entering.

The cells that make xylem have an ability to adapt according to the environment. They open up, lose their ends to make a hollow vessel, and they get strength by lignin, it also supports the plant.

Xylem vessel is a vessel type structure present in plants, that hold water for the plant. They are small vessels, and they loose and tight according to the requirement of water of the plant.

Its main function is to transport water and nutrition. It also supports the plant and give strength to tissues and stems.

Thus, the cells that make up xylem have the ability to adapt to their surroundings. They open up, shed their ends to form a hollow vessel, and lignin provides strength and support to the plant.

Answer:

A. In a heterozygous individual, the allele that determines the phenotype

Explanation:

The dominant allele completely hides the expression of the recessive allele. This occurs in cases of Autosomal dominant inheritance. Even when both dominant and recessive alleles are present in the genotype, this is the heterozygous state, only the dominant trait will be expressed. Only one dominant allele is enough to express the dominant phenotype.

Answer:

Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.

WHAT HAPPENS TO OUR BODIES WHEN WE EXERCISE?

What is happening to her circulatory system?

When you exercise, or play football in this case, you are working your muscles and certain places in the body. When this happens, your muscles respire (burn the FOOD to produce ENERGY) more faster than they would normally, so the demand for OXYGEN and GLUCOSE is increased.

As the muscles are performing cellular RESPIRATION quicker than the norm, they need oxygen and glucose to reach them faster (glucose and oxygen are the components for cellular respiration), and also they need to get rid of their CO2 (products of cellular respiration are CARBON DIOXIDE and WATER) so the HEART is now pumping blood around the body at a faster rate in order to provide these cells with what they need. To summarize, the circulatory system has to work harder and faster during exercise to provide the cells at work with glucose and oxygen and to get rid of the waste carbon dioxide.

What is happening to her breathing system?

{Relates to explanation given} The requirement for oxygen is increased so now the respiratory system (in particular the LUNGS) have to work harder and faster to take in more oxygen and to exhale more CO2, thus you begin to breathe faster. To summarize, oxygen is inhaled quicker and carbon dioxide is exhaled quicker, therefore the rate of DIFFUSION is increased.

Answer:

Polygenic traits are considered non-Mendelian because their alleles are located on more than one gene which allows for more alleles and phenotypes.

Explanation:

Examples of polygenic traits are hair color and height. Other traits, such as blood type, show codominance, where there is no dominant or recessive allele.

Answer:

The function of tertiary consumers is to keep the population of primary and secondary consumers under control, in addition to serving as food for quarternary consumers.

Explanation:

As stated in the question above, tertiary consumers are those who feed on secondary and primary consumers within the food chain. They represent a very important trophic level, in addition to allowing the transfer of energy between living beings to flow normally, they manage to control the populations of primary and secondary consumers, which keep nature in balance. In addition, they serve as food for other consumers, the quarternarios consumers.

Answer:

he maize is more likely to proliferate because of the human effect.

Explanation:

If both maize and teosinte are grown in the wild, teosinte is more likely to proliferate. This is because teosinte has certain adaptations that make it better suited to the wild environment.

Maize and teosinte are both members of the grass family, but they differ in several important ways. Maize, also known as corn, is a domesticated crop that has been selectively bred over thousands of years to produce larger, more desirable ears for human consumption. Maize has a much larger ear size than teosinte, and its kernels are also larger and more closely packed together.

Hence, if both maize and teosinte are grown in the wild, teosinte is more likely to proliferate. This is because teosinte has certain adaptations that make it better suited to the wild environment.

Answer:

True.

Explanation:

Yes, fluids can be liquids or gases depending on the different intensity of the cohesion forces that exists between their molecules because these cohesive forces allows the molecules to attach to one another that leads to their state of matter. Cohesion forces such as hydrogen bonding and van der Waals forces are responsible for the bulk property of liquids that resisting separation from one another so due to these bonding, the molecules attach to one another on the basis of strong bonding between molecules.

Answer:

A community can be divided into groups, where each group can present the correct ways to use agro-chemicals safely in different types of activity.

Explanation:

Using a community can be very helpful in teaching the safe use of agrochemicals. This is because, as a community usually has a large number of people, these people can be divided into small groups that will serve as small workshop rooms. Within these groups, the different ways to use agro-chemicals in a safe way, both for the applicator and for the environment, will be shown. Information on the composition of agrochemicals, first aid in case of accidents with the use of these products, among other things, can also be presented.

Answer:

1) Kinetic energy of the truck 1 is 600,000 joules.

Kinetic energy of the truck 2 is 1,837,500 joules.

2 a)Potential energy of truck 1 is 646,800 Joules.

b) Energy lose by the truck 1 just got converted into heat and sound energy during the collision.

Step-by-step explanation:

Mass of the truck 1 and truck 2,m = 3000 kg

Velocity of the truck 1,  = = 20 m./s

Velocity of the truck 2, = 35 m./s

1. Kinetic energy of the truck 1:

Kinetic energy of the truck 2:

2.a) Energy loose by the truck 1:

Initial height of the truck on the hill = 22 m

At that height potential energy will be maximum:

Potential energy of truck 1 at that height =

b) Energy lost by the truck 1 just got converted into heat and sound energy during the collision.
