can anyone explain me the Transpiration Pull in plants?
Answer:
As the water is lost from the leaf surface by transpiration, more water molecules are pulled up due to the tendency of water molecules to remain joined (cohesion), and thus to produce a continuous column of water through the stem is called transpiration pull.

Answer:
A B and C but not D
Explanation:
Moving from a Hight concentration gradient to a low concentration gradient means moving from an area where a substance in quantity to an area where it is lower in quantity. D is the only one showing something to be moved against a concentration gradient because there are more squares inside the cell than outside the cell yet the squares are still being moved into the cell.

Explanation:
A class is debating the advantages and disadvantages of different types of reproduction. One student argues that organisms that reproduce asexually, like bacteria, have no advantage over organisms that reproduce sexually.
Which of the following choices below represents an argument for the advantages of asexual reproduction?
A. Organisms that reproduce asexually are likely to find a mate at a faster rate than sexually reproducing organisms, which allows them to reproduce faster.
B. Organisms that reproduce asexually are more diverse and are more likely to pass on key genes for survival to future generations, which aids in maintaining beneficial genes for survival in the gene pool
C. Organisms that reproduce asexually gain variation through processes like crossing over, which allows survival in instances of ecological change
D. Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population
Answer: D. Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population.
Explanation:
When an organism is able to reproduce asexually as opposed to sexually, it means that they do not require a mate to make offspring. Offspring of such organisms will therefore receive all their genes from one source.
Such organisms are able to reproduce very fast when they are presented with adequate conditions especially because they do not need another organism to do so. They will neither have to waste much energy nor have to go through the whole sexual process so they will be able to produce lots of offspring.
Animals are known to have offspring through asexual and/or sexual reproduction. The choices that has an argument for the advantages of asexual reproduction is that Organisms that reproduce asexually create a large amount of offspring in a short period of time in order to maintain their population.
Asexual reproduction is simply known as a type of reproduction where offspring are genetically identical to the parent.The offspring are regarded as clones that derives its root from the original parent.
A single individual can have offspring asexually and also in large numbers quickly.

What is chromosome ?
A chromosome is a thread-like structure present in the nucleus of cells such as both prokaryotic and eukaryotic cell and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.

In the biosphere, _________________ is an important element in ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic acid).
A. Phosphorus
B. Phosphate
C. Photosynthesis
D. Photons
In the biosphere, phosphorus is an important element in ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic Acid), which is in Option A, as phosphorus is a crucial element in the biosphere as it is a component of both ATP (Adenosine triphosphate) and DNA (Deoxyribonucleic Acid).
What is phosphorus?Phosphorus is essential for the formation of the backbone of the DNA molecule, where it links the sugar and nitrogenous base components of the nucleotides. The phosphate group of each nucleotide forms a covalent bond with the sugar molecule of the adjacent nucleotide, forming a long, stable chain of nucleotides that make up the DNA molecule. The DNA molecule is responsible for transmitting genetic information from parent to offspring and serves as a blueprint for the development and function of living organisms.
Hence, in the biosphere, phosphorus is an important element in ATP (adenosine triphosphate) and DNA (deoxyribonucleic acid), which are in Option A.

How many alleles are typically found for mitochondrial genes?
1. 8
2. 1
3. 4
4. 2
Answer:
The answer is 2.1
Answer:
two alleles
Explanation: because This dynamic aspect of mitochondrial transmission from cell to cell is termed mitotic segregation. In Mendelian genetics, a person's nuclear DNA can contain, at most, only two alleles for any particular autosomal gene, one paternally derived (e.g., allele “A”) and the other maternally derived (e.g., allele “B”).
