define acceleration. Write its formula and SI unit . pls answer my question!
Answer:
the rate of change of velocity with time is called acceleration.
it can also be defined as the increase in velocity per second.
The S.I. unit of acceleration is meter per second square or ms−2.
formula; a = Δv / Δt
where a is acceleration,
Δv is the change in velocity,
and Δt is the amount of time it took for that change to occur.
What are the two components of the scientific name of a species in the Linnaean system? Select all that apply. Genus, Specific epithet, Phylum, Family.
Answer:
Genus, Specific epithet
Explanation:
The scientific name was created to establish a standardized language that would allow scientists and scholars around the world to be able to present living beings independently of their native language.
For this purpose, it was decided that the scientific name would be a binomial composition, that is, it would use two names. The first name refers to the genus to which the species belongs, the second name refers to the specific epithet that is the specific descriptor of that species. In addition, the scientific name should be written in italics and have the first initial letter written in uppercase. Ex: Homo sapiens.

Evolution is defined as a change in allele frequencies in a population over time.How is the relationship between malaria and sickle cell n example of human evolution?
Answer:
Dramatic evolution within human genome may have been caused by malaria parasite. A genetic mutation that protects people from a common form of malaria spread like wildfire in sub-Saharan Africa about 42,000 years ago, according to a new study.
People develop sickle-cell disease, a condition in which the red blood cells are abnormally shaped, if they inherit two faulty copies of the gene for the oxygen-carrying protein haemoglobin. The faulty gene persists because even carrying one copy of it confers some resistance to malaria.05-May-2011
Explanation:
An evolutionary force, called balancing selection, appears to be responsible for maintaining defects in our DNA associated with diseases, such as sickle cell anemia, because the mutation's damaging effects might be offset — in a biological way of thinking — by its potential benefits.

Why was the Nationalist Party more popular in China’s cities than in the countryside? Wealthy people who supported the party were concentrated in cities. People in the countryside were less active in politics than people in the city. Poor city dwellers hoped the Nationalist Party would bring economic change. The Nationalist Party threatened to end crop trade with Western nations.

Which characteristic does a virus have in common with a eukaryotic cell?
Viruses are not cells; they are a strand of genetic material within a protective protein coat called a capsid. They infect a wide variety of organisms, including both eukaryotes and prokaryotes. Once inside the cell, they use the cell's ATP, ribosomes, enzymes, and other cellular parts to replicate.
The characteristics that a virus cell possess with eukaryotic cell is that they both possess a genetic material.
What is an eukaryotic cell?An eukaryotic cell is a cell that has a genetic material bound by membrane-bound nucleus.
A virus cell, on the other hand, is a cell that is incapable of replicating itself without a living host.
However, one similarity between the eukaryotic cell and viral cell is that they both possess a genetic material that stores their genetic information.

What happens when volcanoes release greenhouse gases into the atmosphere?
Answer:
a. the climate gets warmer...
Explanation:
When volcanoes release greenhouse gases into the atmosphere, global warming is due to the greenhouse effect.
What do you mean by the Greenhouse effect?The Greenhouse effect may be defined as the phenomenon of keeping the earth warm due to the presence of certain gases in the atmosphere.
Greenhouse gases like carbon dioxide, Methane, and Nitrous oxide allow the solar radiations to enter but prevent the escape of heat radiations of longer wavelength.
Due to this, the gradual and continuous increase in the average temperature of the earth's surface occurs, a phenomenon known as global warming.
Therefore, when volcanoes release greenhouse gases into the atmosphere, global warming is due to the greenhouse effect.

In brief state what happens when a) dry apricots are left transferred to sugar solution? b) a Red Blood Cell is kept in concentrated saline solution? c) the Plasma-membrane of a cell breaks down? d) rheo leaves are boiled in water first and then a drop of sugar syrup is put on it? e) golgi apparatus is removed from the cell?
Answer:
Explanation:
(a) Dry apricots when placed in pure water swell due to osmosis and when in sugar water, they shrink again.
(b) When a Red Blood Cell is placed in concentrated saline solution exosmosis occurs and the RBCs shrink due to excess loss of water.
(c) Breaking of the plasma membrane leads to the scattering of the ceil organelles as it forms the basic supporting unit of the cell.
(d) When Rheo leaves are boiled in water first and then a drop of sugar syrup is put on it, osmosis does not occurs, due to the death of the cells of the leaf. This shows that selective permeability is property of living plasma membrane.
(e) Golgi complex helps in the package, storage and transfer of proteins synthesized by ribosomes. Thus, when ribosomes are removed the cell will not function properly
Endometriosis occurs when endometrial tissue, which normally grows inside the uterus, grows outside the uterus. Based on the model, what effects would you expect these growths to have on the female reproductive system and on fertility?
Answer:
Endometrosis could negatively affect the probability of gestating an embryo if they are growing inward. The affection of the fallopian tubes and the uterus could alter the implantation or even generate complications for the embryo during pregnancy.
In addition, endometriosis generates painful conditions in the abdominal area to the point that it is considered as menstrual cramps during menstruation, women who suffer from this disease suffer a lot during the menstrual cycle.
Regarding the reproductive system, those female reproductive systems that suffer from this disease are considered potentially malignant, since many malignant neoplasms are incited to appear in these foci of excessive proliferation of the endometrium.
Explanation:
Endometriosis can affect the walls of the fallopian tube and the uterus, since it occurs in the endometrium, that is why it bears that name.
The macroscopic appearance of this lesion at the histological level is a tumor nodule, since they are proliferative foci.
Answer:
abnormal tissue growing on the ovaries might affect ovulation, making it harder or impossible for women to get pregnant. The extra tissue may cause pain, since the tissue is growing in places it is not meant to be growing

Answer:
Induced fit
Explanation:
Induced fit (IF) is a model used to understand enzyme-substrate interactions, which can be considered as a development of the classical lock-and-key model. This model (IF) was proposed by Daniel Koshland (1958) in order to understand protein conformational changes during the binding process. The model states that the active site of the enzyme, i.e., the region where the substrate binds and catalyzes the reaction, is reshaped when it binds with its substrate in order to improve the fit. The IF model assumes that the active site of the enzyme is flexible and is capable of changing its shape until the substrate is completely bound.

Arrange the sentences in order to describe how oxygen from air is transported to the cells in the kidneys.
Answer:
The pulmonary veins carry oxygenated blood to the heart. Air enters the bronchioles in the lungs and reaches the alveoli. The capillaries join together to reach the arteries, transferring the oxygen. The oxygen-rich blood moves from the aorta and reaches the kidneys through a series of blood vessels.

B. could destroy the hypothasis of continental drift
C. could not provide a mechanism for moving continents
D. could explain how the seafloor was being destroyed
Answer:
C. could not provide a mechanism for moving continents
Explanation:
Magnetic reversals have the habit of causing geological displacements, since they are directly linked to the movements and distribution of tectonic plates on the planet, which are responsible for the movements of the continents. In this case,
if the discovery of magnetic reversals recorded on the ocean floor were not carried out, it would be impossible to establish its relationship with the movement of the tectonic plates, making it impossible to provide a mechanism for moving continents.
