The honeybee decline, which is affecting domesticated and wild bee populations
around the world, is mostly the result of diseases spread as a result of mites and other
parasites as well as the spraying of crops with pesticides, scientists say.…

The decrease in the honeybee population is partly due to
(1) the use of pesticides (3) the use of fertilizers
(2) a decrease in prey (4) a decrease in fruits and vegetables

Answers

Answer 1

Answer: The decrease in the honeybee population is partly due to the use of pesticides according to this article, although it should be noted that there are other factors as well.

Answer 2

Answer:

I would also have to say: 1) the use of pesticides

I did a powerpoint presentation on the decrease of honeybees for biology in college. I cannot find the presentation I did however, I do remember some of the points I made.

Varroa Mites aka Varroa destructors (parasite) are also contributing to the honey bee population decreasing. They latch onto the honeybees and feed off of them. They also feed off of the larva's (baby version of a honeybee).

Another issue could be that GMOs. Plants DNAs have been altered so that they can fight disease and kill unwanted bugs.

Another issue is population ecology, which deals with density independent and dependent factors. Density-independent, deals with habitat destruction by natural disasters or humans. Dependent factors- overcrowding of an area.

Hopefully this helped and good luck.

Im guinea pigs, short hair is dominant and long hair is recessive. A short haired male and a short haired female produced mostly short haired offspring but a few were long haired. show how you can determine the genotypes of the parents

Answers

Answer/Explanation:

Let's say the allele for short hair is S and the allele for long hair is s. Since long hair is recessive, an individual would need to have two copies of that allele to show the genotype (h0m0zygous - ss). That means they must inherit one from each parent.

A guinea pig with short hair could be h0m0zygous (SS) or heterozygous (Ss)

Since a short haired male and a short haired female produced some long haired offspring, they must each have a copy of the long haired allele (s). Otherwise there is no way their offspring could inherit two copies of the s allele. The offspring must have got one s allele from each parent.

Therefore, the parents must both be heter0zygous (Ss)

The process in which two gametes fuse to make one cell is called _____.asexual reproduction
fertilization
conjugation
pollination

Answers

The answer is fertilization.

Fertilization is the process in which two gametes fuse to creates one cell. In this process male sperm fuses with female egg which creates a zygote.

Asexual reproduction involves the formation of offsprings without gamete fusion. Conjugation is a process of exchange genetic material between bacteria. Pollination is a process of transfer pollen to the female reproductive structures in plants, which enables fertilization.

Answer:

The answer is fertilization.

Which trilobite characteristic did not change through time?

Answers

The answer is a presence of three lobes.

The name trilobite means three lobes. Their body is divided into three lobes - a central axial and two pleural lobes. This characteristic did not change through time and it can be found between all fossils. But, some changes are noticed regarding the eyes size, shape, and position, suture position, as well as a number of body segments and spine.

When you step on a sharp object we move our foot away at once . what type of response is this?

Answers

It is innate response (reflex), automatic, occurs through the stimulation of specific receptors, nerve endings and sensory nerve stimulation of effector organs (mainly muscles) through the motor nerves or autonomous. Reflex reaction proceeds without awareness, it means that the nerves cause reflex (stimulate muscles) before notifying the brain.

Which of the following climates is a high-latitude climate?a. highland
b. tundra
c. humid continental
d. subarctic

Answers

The answer is d. subarctic

A latitude is a measure of position north or south of the equator. On the equator, the latitude is 0 degrees, and on the poles, it is 90 degrees. The high-latitude climates are in high latitudes, thus on the poles. the subarctic climate spreads between 50 and 70 degrees of latitude, thus, it belongs to the high-latitude climate.

Answer:

highland

Explanation:

I verified on a quiz that it is correct.
