If two hybrid tall pea plants are crossed what is the probability that the offspring will have the tall phenotype?
Answer:
There is a high probability that the Pea plant will have a High phenotype!
Explanation:
Because both "parent plants" are tall, this will cause the offspring to also be tall, this will be because it in it's genes or in other words DNA too be strong.
Which situation is a result of crossing-over during meiosis?
A
Genes are duplicated exactly, ensuring that offspring will be
identical to the parents.
B
Chromatids thicken and align themselves, helping to ensure
genetic continuity.
с
Genes are rearranged, increasing the variability of offspring.
D
Chromatids fail to sort independently, creating abnormal
chromosome numbers.
Answer:
C
Explanation: Genes are rearranged due to crossing over and offspring can vary in traits and appearance
Which best describes the blood flowing in an artery?
A. It is oxygen rich
B. It contains no red blood cells.
C. It moves toward the heart.
D. It is oxygen poor.
It is oxygen rich
What do you mean by arteries?
The arteries are the blood vessels that deliver oxygen-rich blood from the heart to the tissues of the body. Each artery is a muscular tube lined by smooth tissue and has three layers: The intima, the inner layer lined by a smooth tissue called endothelium.
What is oxygenated blood?
Oxygenated blood can be simply defined as a blood cell with large percentage of oxygen and low in carbon dioxide. It appears bright red in color and travels away from the heart to different parts of the body.

Which of the following describes a negative feedback loop?
A. When the heart rate is too high, the body releases hormones that continually increase the heart rate higher.
B. When a pregnant woman is in labor, the body releases hormones that increase the intensity of contractions, which then increases the secretion of the same hormones.
C. When blood sugar concentration is above normal, the endocrine system releases hormones that lower the blood sugar concentration until it reaches a normal level, and the release of the hormones slows.
D. When a person is jogging, the body releases hormones that continually decrease the rate of oxygen supply to the legs.
ANSWER is A
When blood sugar concentration is too low, the endocrine system secretes hormones that increase blood sugar concentration to a normal level.

Answer:
light moths
Explanation:
yes their were most light color in most trees
Light moths was more common before the 19th century, when most trees were light in color.
What are the functions of light moths?Insects, like moths, are drawn to bright lights because they make it difficult for them to navigate. It's a common sight, particularly in the summer: The lights, like lamps, were surrounded by moths and other insects.
Most nocturnally dynamic moths are drawn to light, a peculiarity known as sure phototaxis. However, because they are phototactic, some species, like the Old Lady (Mormo maura), tend to avoid it.
No one really knows why moths are drawn to light, but there are a few theories, and they also like the smell of fermented sugar and ripe fruit, which are both food sources.

How do volcanoes provide evidence to scientists to support the idea that matter and energy move within the Earth’s interior?
Answer:
Scientists use volcanic activity data from this area to show the relationship between volcanic activity and lithospheric plate motion. Hot Spots and Plate Tectonics: A volcanic hot-spot is an area in the mantle from which heat rises in the form of a thermal plume from deep within the Earth. Higher heat and lower pressure at the base of the lithosphere melts rock and forms magma.

The mass of a cylinder of beetroot was 2.5 g. If its final
mass was 2.7 g, what was the
increase in mass in per cent?
Answer: The percent increase in the mass of cylinder of beetroot is 8%.
Explanation:
To calculate the percent increase in the mass of cylinder, we use the equation:
[tex]\%\text{ increase in mass}=\frac{\text{Final mass - Initial mass}}{\text{Initial mass}}\times 100[/tex]
We are given:
Final mass of the cylinder = 2.7 g
Initial mass of the cylinder = 2.5 g
Putting values in above equation, we get:
[tex]\%\text{ increase in mass}=\frac{2.7-2.5}{2.5}\times 100\\\\\%\text{ increase in mass}=8\%[/tex]
Hence, the percent increase in the mass of cylinder of beetroot is 8%.
Which animals are the main consumers of the Pan dropseed (Sporobolus ioclados) ?
Answer:
elephants
Explanation:
The animals that are the main consumers of the Pan dropseed are all animals have complex organ systems. Especially Seed-eating birds including American sparrows, and elephants.
What is Sporobolus ioclados?The grass family contains a nearly universal genus of plants called Sporobolus. The genus' members are frequently referred to as dropseeds or sacaton grasses.
They grow in numerous sorts of open habitat in warmer temperatures and are typical grassland and savanna plants. At least one species, as well as another, are endangered.
Only alkali sacaton has the little moth Bucculatrix sporobolella's caterpillar been discovered (Sporobolus airoides).
On Laysan Island, it appears that the local elimination of S. virginicus by feral rabbits led to the extinction of the Laysan dropseed noctuid moth (Hypena laysanensis).
All of the animals that eat the Pan dropseed most frequently have intricate organ systems, including seed-eating birds including American sparrows, and elephants
Thus, these are the animals that are the main consumers of the Pan dropseed.

why would an athlete need to be concerned about a twitch or sustained contraction
Answer:
why an athlete would need to be concerned about twitches or contractions is because, whenever they perform, and such thing happens, it will most likely distract the athlete, and cause the athlete doing his/her performance to not be as good, and may lead to failure, for example, when someone is running very fast for a sprinting race, and he has a contraction in his leg it will cause him to react by showing signs of pain by slowing down or even tripping and falling, causing him to lose the race.

Mutation is any alteration or change in the genetic sequence of a gene caused by mutagens (substances) or mistakes during replication of genetic sequences.
A mutation occurs in the gene from time to time, although, the cell has protocols in place to put them under control if they occur. However, when DNA or a gene is being copied and transferred to offsprings, there is bound for mistakes called MUTATION to occur.

Answer:
[tex]D_m=1/2[/tex]
Explanation:
From the question we are told that
2 species
Assuming that questions a and be are solved
Diversity index D=2p_1p_2
with [tex]p_1 +p_2 =1[/tex]
Mathematically
[tex]D=2p_1(1-p_1)[/tex]
[tex]D=2(p_1-p_1^2)[/tex]
[tex]D=2({\frac{1}{4} -(p_1-1/2)^2}[/tex]
Therefore
