tom of classification.
Answer:
The continuous evaporation of water (or transpiration) from the cells of a leaf crates a kind of suction which pulls up water through the xylem vessles. Thus, transpiration helps in the upward movement of water and dissolved minerals from the roots to the leaves through the stem.

Answer:
The answer is B an Organ system
Answer:
an organ system
Explanation:
The correct answer is organ system. A tissue is a group of cells working together to achieve a common function. An embryo is a fertilized egg that has developed from a zygote. Multipotent merely refers to a type of stem cell that has limited specialization capabilities relative to the capabilities of totipotent and pluripotent cells.

Where does that air go as a result?
Answer:
Air go from one place to another due to difference in temperature of land and sea.
Explanation:
Air go as a result of wind from one place to another. Air moves from land to sea is called land breeze and from sea to land is known as sea breeze. This will occur when there is difference in temperature between sea and land. Sea breeze occurs at afternoon while land breeze occurs at night till morning. Warm air produces low pressure and cold air produces high pressure so when warm air rises, cold air takes its place and this cycle continues.

Why do you think premenopausal women need more iron than
men of the same age?
Answer:
Women need more iron than men to make up for the amount of iron they lose in their menstrual period.
Explanation:
Answer:
Premenopausal women shed blood as part of menstruation every month, which lowers the level of iron in the body. So, they need more iron than men and are also at a greater risk for this nutritional deficiency.

g In humans and higher primates, _____ is the final product of purine base catabolism and is excreted in urine. However, its inadequate excretion is a cause of a disease called ______
Answer: Humans and greater primates excrete water, broken down proteins and Urea. Many things cause unusual urine, Urea gives urine its yellow color a lack of urea can mean kidney failure. however it's hard to tell a lack of urea by just looking at urine as drinking excessive amounts of water turns the color clear and drinking caffeine turns the color reddish or brown so lab testing must be done

Explanation:
In the quest to understand the basis of infertility in humans, researchers have identified a mutation in a gene associated with chiasmata. This protein normally acts to promote homologous recombination.Why might a defect in homologous recombination have consequences for fertility?A. The chiasmata halts the whole process of meiosis, if crossover do not form properly.B. Crossover formation is a necessary step in meiosis I to ensure proper chromosome segregationC. A checkpoint requires a certain level of genetic variability for meiosis to proceed.D. Chiasmata are the connections between the centromeres and the centromeres that pull them to each pole of the daughter cells.
Answer:
B. Crossover formation is a necessary step in meiosis I to ensure proper chromosome segregation
Explanation:
Crossing-over is a unique phenomenon that occurs in the prophase I stage of meiosis I, where non-sister chromatids of homologous chromosomes exchange their chromosomal segment. The physical point where this exchange occurs is called CHIASMATA. Hence, a mutation that affects the gene associated with the chiasmata will affect the occurrence of crossing over or homologous recombination.
Crossing-over, through the formation of the chiasmata, is responsible for the physical alignment and proper segregation of chromosomes into gametes. Naturally, the chiasmata formed as a result of recombination during meiosis helps ensure that the chromosomes stay together until it is the right time to separate. This way, any chromosomal defect in the resulting gamete is prevented.
However, an error or defect in homologous recombination might give rise to gametes with chromosomal disorder, a condition known as ANEUPLOIDY i.e. missing or additional chromosomes in gametes. This can affect the fertility of the involved human.

he most common source of osteomyelitis is an infection that migrates via the bloodstream. direct invasion from a fracture. surgical contamination. a joint prosthesis.
The correct answer is A. An infection that migrates via the bloodstream
Explanation:
Osteomyelitis is a serious condition, in which an infection develops in bones. This causes symptoms such as pain, inflammation, and can lead to the spread of the infection to other tissues or bone necrosis if it is not treated. In terms of causes, this condition develops when the bone is exposed to bacteria or similar that causes the infection, this can occur during surgeries or fractures. However, the most common source of infection is via bloodstream this means the bacteria or germ is in the blood and it enters the bone through the bloodstream. Also, once the bacteria or germ is in the bone it causes the infection.

Answer:
The correct answer is - option A. 1 (ovary).
Explanation:
Oocytes or egg are produced in the ovaries during the process of the female gametogenesis in female reproductive system. Ovaries are located on each side of the uterus that are oval and small in shape and size and located lower abdomen.
Among other female reproductive organs these are located above others. The ovaries produce oocytes and hormones It is the site at which primordial germ cell (PGC), become primary oocytes.
Thus, the correct answer is - option A. 1 (ovary).
Acidification of the stomach uses all of the following types of transport EXCEPT: A. channels. B. pumps. C. antiporters. AND. symporters. E. All of these are used by parietal cells.
Answer: Option E.
All of these are used by parietal cells.
Explanation:
Parietal cells are found in the stomach and they produced gastric acid(Hcl)..
HCl is produced when water mixed with carbondioxide in the parietal cell to produced carbonic acid which is catalyses by carbonic anhydrase. The carbonic acid then dissociates into hydrogen ion and carbonate ion.
Parietal cell produce HCl due to histamine (via H2 receptors), acetylcholine (M3 receptors) and gastrin (gastrin receptors).
Therefore it uses channels, pumps, antiporter.

Which of the following groups could be identified using the biological species concept? Select all that apply. Select all that apply. bacteria living today extinct dinosaurs sunflower species living today lizard species living today
Answer:
Bacteria, Sunflowers, Lizards.
Explanation:
They are all biological species due to being apart of flora and fauna. It wouldn't be dinosaurs since biologists study living things, dinosaurs are extinct.
The groups 'sunflower species living today' and 'lizard species living today' could be identified using the biological species concept.
The biological species concept defines a species as a special group of interfertile individuals.These individuals can then cross in order to produce fertile offspring and thus perpetuate the species.The biological species concept was developed by the biologist Ernst Mayr.In conclusion, the groups 'sunflower species living today' and 'lizard species living today' could be identified using the biological species concept.

What are similarities and differences between insects that go through complete metamorphosis and incomplete metamorphosis?
There are two types of metamorphosis-incomplete and complete.
In incomplete metamorphosis, an adult insect lays an egg. The egg hatches into a nymph, which is like a mini adult. This nymph then grows into an adult. As the nymph grows, it molts several times. Grasshoppers are examples of insects that undergo incomplete metamorphosis.

Answer:
The answer is "inflorescence, oak"
Explanation:
An inflorescence is a flower group, which are clustered nearby in a stalk, which is also known as the peduncle. In lily, the individual flower was found, not quite as groups. However, the flowers are set as an inflorescence in the oak tree. It refers to a group or community of a flower cluster borne on a flower, which is traditional flowers of oak are called catkins, that's why 'inflorescence, oak' is the reaction.
