Which of these is a biotic factor in an ecosystem?

Answer:

The Y chromosome do not go through crossover

Explanation:

Typically, genes from the mother and father are shuffled -- or, "cross over" -- to produce a genetic combination unique to each offspring. But the Y chromosome does not undergo crossing over, and, as a result, its genes tend to degenerate, while repetitive DNA sequences accumulate. Each chromosome is made up of DNA.

Answer:

it is the y chromosomes that do not go through crossover.

Answer:

dominant

Explanation:

The "gene" of an organism consists of two alleles. One allele comes from each parent. A genetic trait is said to be "dominant" even if there's only one copy of dominant allele present; however, a genetic trait is said to be "recessive" if there are two recessive alleles present.

In Black Angus cattle, the dominant color is "black." They are even named after their color. The recessive trait is "red." In order for a Black Angus cattle to be red, it needs to have two alleles for the recessive trait (red). However, it is easy for the cattle to be black as long as it has one allele for the dominant trait.

Answer:

According to the hormone diagram of the menstrual cycle, the woman is not pregnant due to the behavior of progesterone and estrogens, whose levels do not increase, in addition to the absence of human chorionic gonadotropin.

Explanation:

The graph shows the behavior of hormones during a woman's menstrual cycle in the absence of pregnancy.

During a woman's normal cycle, estrogen, luteinizing hormone (LH) and follicle stimulating hormone (FSH) tend to increase prior to ovulation, reach their peak values at ovulation, and then decline, as shown in the graph. Progesterone, on the other hand, increases after ovulation and decreases if the woman does not become pregnant.

In the case of a pregnant woman:

The diagram represents the normal cycle of a woman who is not pregnant.

Answer:

10

Explanation:

Mitosis is the division of somatic cells in which the genetic content or number of chromosomes remain intact in daughter cells.

So the correct option is 10

The number of chromosomes will be 10.

Thus, if a parent cell has 10 chromosomes, 10 will be in each daughter cell after mitosis.

A number of human activities can impact on the water cycle: damming rivers for hydroelectricity, using water for farming, deforestation and the burning of fossil fuels.

Explanation:

Answer:

In order to play a crucial role in controlling blood sugar levels, all hormones act in balance. Blood sugar levels can spike or drop if the level of one hormone is higher or lower than the ideal range. Insulin and glucagon, together, help sustain a state called homeostasis in which conditions stay steady within the body.

Answer:

When animals take fruits or seeds for food, they act as willing transporters of the plant's seeds. Animals can disperse seeds by excreting or burying them

Humans may disperse seeds by many various means and some surprisingly high distances have been repeatedly measured; seeds may get caught in humans clothes/shoes/cars

Explanation:

Answer:Some fruits,like cocklebur,have books or sticky structures and stick to an Animal's fur.

Explanation:

Humans also play a role as disperse by moving fruits to new to new places and discarding the inedible portions containing Seeds.

Answer:

In the vacuum of space, there are no (or very, very few) particles to vibrate, so sound cannot travel through this medium. ... Radio waves travel perfectly fine through a vacuum because they are a type of electromagnetic wave (light), and electromagnetic waves do not need a medium to travel through. Light waves are transverse while sound waves are longitudinal. Light waves can travel in vacuum. Sound waves require a material medium to travel, and hence, cannot travel in vacuum. ... Light waves can be polarized, but sound waves cannot.

Explanation:

hope this helps have a good day :) ❤

Answer:

sound needs something to bounce back in order for it to be able to come back to your ears so in space where its a bunch of nothingness tht is not possible

Explanation:

a more detail explanation

Light can travel in vacuum but sound cannot. This’s because sound waves are vibrating waves (also called pressure waves ) travel by physical contact of molecules. Sound can travel in air, metals like steel or aluminium. Light speed is constant. But in case of sound denser the medium faster the speed

The Modern World, where everything is artificial and ephemeral; where you have to pay for a "need" created or for clean air.

The greed of man to generate wealth and status regardless of the impact it generates on his environment, to be accepted by his family and society.

Unsustainable production systems, which destroy ecosystems and alter the life of the animals that live there.

Children living in the Modern World, who know little about the nature and the effect of our actions on the environment.

Caring for the environment is in the hands of the new generations, especially those who really care.

Explanation:

Answer:

The mean for the length of the 6 worms is 84 millimetres.

Explanation:

Okay, before we solve for the mean, you need to understand what the mean is in the first place.

The mean is when you add all the given numbers and then divide by the amount of numbers given.

In this case, we have the numbers 96, 88, 86, 84, 80, 70.

These are the steps:

1. Add all the numbers

         96 + 88 + 86 + 84 + 80 + 70 = 504

2. Divide the total of the given numbers by the amount of numbers given.

         In this case, it is 6. So it would be 504/6, which equals to 84.

Also, don't forget to put the unit.

Hope this helped. :)

Answer:

More food is available for predators.

Explanation:

If biologists kept introducing hares into the environment to keep the hare population at a high and constant level so there is more availability of food for the predator and so the population of predator increases. If there is no predator for the hare so it will increase in number and eliminate all the vegetation of the environment while on the other hand, if the biologists kept only the lynx population at a high and constant level so it decreases the population of hares because lynx feeds on hare.

Answer:

2 out of 4

Explanation:

Let the allele for cleft chin be represented by A, while the alternate recessive version would be a.

A parent that is heterozygous for cleft chin would have the genotype Aa.

A parent without cleft chin would have the genotype aa.

             Aa    x    aa

          Aa   Aa   aa   aa

Aa - cleft chinned = 2/4

aa - normal chin = 2/4

Thus, two out of every four (2/4) of their offspring would have cleft chin.

Answer:

The first error is they put an arrow to oxygen twice. The secound error is they made one of the arrow point toward oxygen, when it should be the other way around. the third error is about glucose, while the plant does use it, it may not stay in the plant. if the plant if a fruit plant, the glucose/suger will go into the fruit, which caused the fruit to have a sweet taste.

Cancer

Explanation:

Cancer is a disease in which abnormal cells divide uncontrollably and destroy body tissue.

B- The organism cell structure

The options you can rule out:

A- The organisms’ reproductive rate isn’t important since it’s just telling how fast the organism can grow, and it doesn’t provide information on where to assign it to a domain and kingdom.

C- The organisms’ population size of the organism isn’t important since it just shows how many there are, but it doesn’t provide information on where to assign it to a domain and kingdom

D- The organisms’ social behavior can be important (since it’s talking about how the organism acts and behaves toward other organisms, but it isn’t important on where to assign it to a domain and kingdom

Hence,

If scientists discovered a new type of organism, Option B: knowing the organism cell structure is most important, because it goes in dept on what the specific formation of the organism. Looking at the cell structure provides information on what where to assign is to a domain and kingdom.

Answer:

B

Explanation:

Answer:

Explanation:

         The leaves and stems of many desert plants have a thick, waxy covering. This waxy substance does not cover the stomata, but it covers most of the leaves, keeping the plants cooler and reducing evaporative loss. Small leaves on desert plants also help reduce moisture loss during transpiration.
