Answer:
Precipitation ahead of a warm front typically forms into a large shield of steady rain or snow. After the warm front passes, fair and milder weather is typical, however, a cold front is likely not far behind.
why people living in high altitude have level of RBC?
Answer:
Scientists have long known that the body adjusts to the oxygen-deprived conditions of high altitudes. ... The traditional explanation has been that low-oxygen conditions cause the body to build new red blood cells, making it easier to supply oxygen to muscles and vital organs.
is it more beneficial for humans to undergo sexual reproduction than asexual reproduction?
Answer:Advantages and disadvantages of sexual and asexual reproduction
Sexual reproduction involves two parents and the joining of male and female gametes during fertilisation. The offspring inherit a mixture of genes from both parents, so are different to each other and their parents.
The advantages of sexual reproduction:
produces genetic variation in the offspring
the species can adapt to new environments due to variation, which gives them a survival advantage
a disease is less likely to affect all the individuals in a population
In asexual reproduction there is only one parent. The offspring are clones of the parent and each other.
The advantages of asexual reproduction include:
the population can increase rapidly when the conditions are favourable
only one parent is needed
it is more time and energy efficient as you don't need a mate
it is faster than sexual reproduction
The disadvantages of sexual reproduction:
time and energy are needed to find a mate
it is not possible for an isolated individual to reproduce
The disadvantages of asexual reproduction include:
it does not lead to genetic variation in a population
the species may only be suited to one habitat
disease may affect all the individuals in a population
Examples in the natural world
Bacterial reproduction
Bacteria, such as E. coli, reproduce asexually. An advantage of this is that they can produce many bacteria very quickly. A disadvantage is that all of the bacteria are genetically identical. If an antibiotic was used on the bacteria, then all of them would die. The population would be wiped out. The only way for variation to be introduced into the population is by random mutation.
Rabbit reproduction
Most animals reproduce sexually, for example, rabbits. The process of sexual reproduction introduces variation into the species because the alleles that the mother and the father carry are mixed together in the offspring. A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop. The benefit of introducing genetic variation into the species, however, outweighs this disadvantage. If a disease were to hit the rabbit population, then perhaps not all of the rabbits would be affected because of the variation in the population. This means that some individuals would survive and be able to reproduce and generate more offspring.
Asexual and sexual reproduction in fungi
Some fungi are able to reproduce both sexually and asexually. Fungi reproduce using spores which they release into the environment. A new fungus will grow from the spore. The Coprinus cinereus fungus can produce spores by sexual reproduction to help create variation in the species. This method of reproduction is advantageous when the environment is changing because the variation introduced leads to an increase in the probability that a variant that can deal with the change. Coprinus cinereus also produces spores by asexual reproduction. These spores can be produced quickly and in large numbers to enable many individual fungi to develop. A disadvantage of these spores is that they generate offspring that are unlikely to be resistant to unfavourable conditions because they are all genetically identical.

If a cell with 42 chromosomes undergoes mitosis, how many chromosomes will each daughter cell have?
Answer:
42
Explanation:
If a cell has 42 pairs of chromosomes (n = 42), it has 84 chromosomes (2n = 84). At the end of mitosis, the two daughter cells will be exact copies of the original cell. Each daughter cell will have 84 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 42 chromosomes.
A simple example is↓
The parent cell of 10 chromosomes will end up becoming two daughter cells that each have a copy of those 10 chromosomes.
The important fact about mitosis is that the daughter cells are identical to the parent cell. The daughter cells will have the same number of chromosomes as the parent cell.
If a cell with 42 chromosomes undergoes mitosis, the equal 42 chromosomes will each daughter cell have.
What is Mitosis?
Mitosis is a process where a single cell divides into two identical daughter cells (cell division).
Before a cell divides it undergoes DNA replication. As a cell enters mitosis, double-stranded chromosomes fuse from the replicated DNA. A cell having 42 chromosomes will have 42 double-stranded chromosomes entering mitosis. Upon completion of cell division, each daughter cell will receive 42 single-stranded chromosomes, as double-stranded chromosomes are pulled apart during mitosis.
Therefore, if a cell with 42 chromosomes undergoes mitosis, the equal 42 chromosomes will each daughter cell have.

What are 2 functions of carbohydrates?
A. Carbohydrates are used to store energy and store information in living things.
B. Carbohydrates are used to store energy and provide structure/support in living things.
Answer:
In Short The correct answer is B...
Explanation:
Here are most of the functions of carbohydrates altogether:
Provide instant energy to the body. :This appears to be the primary function of carbohydrates in the body. ...
Reserve food: Carbohydrate is also stored as the reserve food in the body. This is a precautionary measure for the body to cope up in times of hunger.
Carbohydrates form other biomolecules.
Detoxification of the body by metabolism
Carbohydrates participate as reaction intermediates in some vital reactions. This function of carbohydrates is seen extensively in various cellular reaction.
For example, one of the vitamins, Vitamin B2 also called Riboflavin has a ribose sugar moiety. This ribose is a four carbon type of carbohydrate monomer by its chemical structure. It is involved in vital reactions at the organ and cellular level. Similarly, carbohydrates are also chemical constituents of many hormones, vitamins, enzymes, etc.
Carbohydrates form a part of DNA and RNA in the form of deoxyribose and ribose sugars. These are five carbon monosaccharides formed form heptulose sugars by the pseudo-heptulose pathway.
They are constituents of all the cellular organelles. Carbohydrates are also components of cell organelles like the cell membrane, mitochondria, nucleus, endoplasmic reticulum, etc. They provide structural integrity, mechanical strength in combination with proteins and lipids. They help make up the body mass by being included in all the parts of the cell and tissues. For example, in cell membranes, there are two constituents, i.e., glycolipid layer and glycoprotein layer. Here the term “glyco” is a carbohydrate.
8. Transport of oxygen: Glucose is taken by red blood cells. These are the types of blood cells which lack mitochondria and other cell organelles required for producing energy. In such a case, the ATP is produced by a non-oxidative pathway with the end product as lactose and ATP.
This energy thus produced is necessary for hemoglobin to bind to oxygen molecules. These bound oxygen molecules are transferred from lungs to the different tissues.
9. Aid in gut motility: Our diet has carbohydrates in greater proportions because, it aids in bowel movement. When you suffer from constipation, doctors first prescribe you bran and other carbohydrate material like Ispaghula. The carbohydrates in these material is in the form of fibrous material. When they are ingested, their material absorbs water in the guts, swells and increases the load.
This load is useful to increase intestinal motility and expulsion of waste (feces). Thus carbohydrates help clear gut and prevent constipation. Hence, when you feel constipated, have banana fruit and notice the change.
They play a role in other physiological roles. Since they are components of many bio-molecules, they have further roles in body physiology. They have a role in blood clotting, immunity, fertilization. Thus they take part in many physiological reactions.
Answer:
B. Carbohydrates are used to store energy and provide structure/support in living things.
Explanation:
The two functions of carbohydrates are to store energy and provide structure/support in living things.

Explanation: Climate change is causing the extinctions of species. But some species will have better chances of survive-al because they were created that way. So, humans for example will have a good chance of survive-al despite of climate change, because we are always innovating and changing, while most plants and animals, are used to one type of climate or region. Although there some cases of plants and animals that can adapt to any struggles of climate.

The cell grows in which phases?
A. G1, S, and G2
B. G1 and S only
C. G2 and S only
D. G1 and G2 only
Answer:
D. G1 and G2 only
Explanation:
Interphase is composed of G1 phase (cell growth), followed by S phase (DNA synthesis), followed by G2 phase (cell growth). At the end of interphase comes the mitotic phase, which is made up of mitosis and cytokinesis and leads to the formation of two daughter cells.
Answer:
D. G1 and G2 only
Explanation:
During interphase, the cell grows (G1), replicates its DNA (S) and prepares for mitosis (G2). A cell in interphase is not simply quiescent.
