statocytes, organelles do plants have in their roots that helps them to sense gravity, correct answer is B.
what are statocytes ?
In higher plants, statocytes are the cells which sense gravity. They contain amyloplasts-statoliths, amyloplastic organelles which are filled by starch or sediment at the bottom of the cells. Coleoptiles, shoots, and inflorescence stems all have an elongating area that really is home to statocytes.
how do they help in sensing gravity ?
When the plant is reoriented in the gravity field, the starch-filled plastids (also known as statoliths) in the statocytes, that are highly polarized cells, fall to the physical bottom.
Hence, statocytes help in sensing gravity.

How were humans born according to evolution?
Answer:
Explanation:
According to the theory of evolution, humans evolved from a common ancestor with other primates such as chimpanzees and gorillas. Over millions of years, a series of gradual genetic changes occurred, leading to the development of characteristics that are specific to humans, such as bipedalism, larger brains, and the development of language and culture.
The process of human evolution is thought to have begun around 7 million years ago, with the split of the human and chimpanzee lineages. The earliest known human ancestors were small-brained, ape-like creatures such as Sahelanthropus, Orrorin and Ardipithecus. As time passed, the human lineage evolved into larger-brained hominins like Australopithecus and eventually to the genus Homo, which includes modern humans, Homo sapiens.
It's worth noting that the evolutionary process is not a linear path, but a complex one with different lineages and divergences, but the most widely accepted scientific explanation is that human beings are the result of a long process of evolution from a common primate ancestor.
Answer:
A long process of which homo-sapiens slowly evolved into humans.

Acupuncture is an alternative medicine that uses wire-thin needles inserted by a trained practitioner into specific points in the body. This ancient form of pain relief and stimulation is said to benefit patients by blocking channels which practitioners claim allow pain to travel within the body. This practice became more widely recognized and used after a New York Times reporter wrote in 1971 of a positive experience with it after surgery.
Those who doubt the effectiveness of this treatment for pain attribute the pain relief to a placebo effect: if a patient believes something will reduce their pain, they will experience some relief. The National Institutes of Health says that acupuncture relieves pain and reduces nausea and vomiting, although it is unclear how it works. The few adverse effects reported are due to improperly sterilized needles or improper delivery, making this still a fairly low risk option. For anyone considering acupuncture, they should first research its effectiveness for their specific condition.

What happens to the volume of a washcloth when it is dry
or wet?
When washcloths are dry then volume decreases and when washcloths are wet then volume increases.
Why does it take longer for a folded wet towel to dry?The surface area closely relates to evaporation. Evaporation is inversely correlated with surface area or vice versa. Folding a wet towel reduces its surface area and slows evaporation, which makes drying take a long time.
Why does it take wet clothing longer to dry on a humid day?Because of the excessive humidity in the summer rain, clothing dries more slowly. The rate of evaporation slows down in the wet summer. Because there is no sun to shine on the garments, humidity is the amount of water in the air. The difference affects how quickly or slowly the material dries.
Why does a windy day make clothes dry more quickly?A windy day will have a high wind speed, which causes more water to evaporate. The amount of water vapor in the air decreases as wind speed increases due to the scattering of water molecules. As a result, on a windy day, garments dry more quickly.

Bowerbirds construct elaborate bowers (nests) and decorate them with different colors to attract females. The Satin bowerbird builds a nest between upright sticks, and decorates with bright blue objects, while the MacGregor's bowerbird builds a tall tunnel of sticks and decorates with bits of white objects.
The two populations have almost identical genes, but the birds cannot
breed with each other. This is most likely because ____
Select one:
A forest separates the two populations of bird
Their different mating rituals separate the two populations
Both species of bird used to breed together until a hurricane randomly killed the some of the birds
The Satin bowerbirds are larger than the McGregor's bower birds
Answer:
Their different mating rituals separate the two populations.
Explanation:
likely the correct answer because the fact that the two populations of bowerbirds have "almost identical genes" suggests that they are closely related, but are unable to breed with each other. This is most likely due to the fact that they have developed different mating rituals, which includes building different types of bowers and decorating them with different colors. This difference in mating rituals would make it unlikely for the two populations to breed, as the females of each population would be attracted to the bowers and decorations that are specific to their own population.

If gastrulation was blocked by an environmental toxin, then__.
If gastrulation was blocked by an environmental toxin, then embryonic germ layers would not form.
When an embryo transitions from a one-dimensional layer of epithelial cells (blastula) to a multilayered, multidimensional structure known as the gastrula, it goes through a youthful developmental process called gastrulation.
The three layers of embryonic tissue, or germ layers, are created as a result of gastrulation. These cells will multiply, move, and differentiate during development into the four main adult tissues: epithelial tissue, connective tissue, muscle tissue, and nerve tissue.
The stages of gastrulation in amniotes are as follows: (1) the embryo develops asymmetries; (2) the primitive streak forms; and (3) cells from the epiblast intrude at the primitive streak and undergo an epithelial to mesenchymal transition to generate the germ layers.

The two points where the axis of rotation intersects the Earth’s surface are called as the poles, one of them is called the North Pole and the other is known as the South Pole. One rotation with respect to Sun is completed in 24 hours, called a solar day.
The Earth rotates in counter-clock direction or from left to right-or eastward direction. Rotation serves three reasons. First, the axis of rotation serves as a reference in setting up the geographic grid of latitude and longitude. Second, it provided a good measure of the passage of time, 24 hours or 1440 minutes or 86,400 seconds a day. Third, it greatly influenced the physical and life processes on Earth
