describe the uptake and movement of water from the soil to the leaves
Answer:
After traveling from the roots to stems through the xylem, water enters leaves via petiole (i.e., the leaf stalk) xylem that branches off from that in the stem. Once water leaves the xylem, it moves across the bundle sheath cells surrounding the veins.1-Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.Plant water uptake, or transpiration, represents the process by which water in soil is drawn into plants and returned in gaseous form to the atmosphere through leaf stomata.Water transport also occurs at the cellular level, as individual cells absorb and release water, and pass it along to neighboring cells. Water enters and leaves cells through osmosis, the passive diffusion of water across a membrane.Most of the water that a plant takes in enters through the root hairs.

Why is it important that meiosis produces a haploid cell? What would happen to subsequent generations if mitosis were used to produce gametes?
Answer:
It is important that meiosis produces a haploid cell because it prevents the number of chromosomes from doubling each generation. If mitosis were used to produce gametes the subsequent generations would be diploid so in the next generations the normal amount of chromosomes would double meaning each subsequent generation would double the number chromosomes again and again.
Explanation:
Meiosis
- the process by which the number of chromosomes is halved during the formation of gametes.
- In human cells, for example, 46 chromosomes are arranged in 23 pairs. Therefore, human cells are diploid i.e. they have two sets of 23 chromosomes per set. During generative reproduction, the sex cells of the parent organism unite with one another and form a fertilized egg. In this situation, each sex cell is gamete. Gametes from haploid human cells, from Greek haplos, which means "single." This term implies that each gamete contains a set of 23 chromosomes in humans. When human gametes unite with each other, the original diploid condition of 46 chromosomes is rebuilt. Meaning cells containing a diploid number of chromosomes are converted into four cells, each of which has a number of haploid chromosomes. In human cells, for example, reproductive cells containing 46 chromosomes produce four cells, each with 23 chromosomes.
Mitosis
- the phase of the cell cycle where the nucleus of a cell is divided into two nuclei with an equal amount of genetic material in both the daughter nuclei. It succeeds the G2 phase and is succeeded by cytoplasmic division after the separation of the nucleus. Mitosis is essential for the growth of the cells and the replacement of worn-out cells. Abnormalities during mitosis may alter the DNA, resulting in genetic disorders.
-In each cycle of cell division, two daughter cells are formed from the parent cell. The cell is also known as equational cell division because the chromosome number in the parent cell and daughter cell is the same.

Meiosis' production of haploid cells is crucial because it stops the chromosome count from doubling every generation.
What is meiosis?Meiosis is a reductional division. The number of chromosomes would double in the following generations if mitosis were utilized to make gametes, making the subsequent generations diploid and doubling the number of chromosomes in each successive generation.
Meiosis is the process by which the number of chromosomes is cut in half as gametes are developing.
For instance, there are 23 pairs of 46 chromosomes in human cells. Human cells therefore have two sets of 23 chromosomes each, making them diploid.
Therefore, Meiosis' production of haploid cells is crucial because it stops the chromosome count from doubling every generation.

which objective lens will still remain in focus when placed at the longest working distance from the specimen?
Answer:
10x objective lens
Explanation:
The objective lens that will still remain in focus when placed at the longest working distance from the specimen is 10x objective lens.
Microscope objectives are set up with a short free working distance. Working distance is knot to be the point or distance from the front lens element of the objective to the closest surface of the coverslip when the specimen is in sharp focus.
The distance between the objective lens and the specimen, when the specimen is in focus, is called the working distance of the lens. The greater the magnification of the lens, the less the working distance; that isConclusively, a 10x objective lens is a low power objectives that has a longer working distances than high power objectives

Amelia has laid the groundwork for a fledgling business and is considering incorporating. Which of the following
is a valid concern that she might have?
A) Acquiring financing as a corporation will be much more challenging than it is for other
business structures.
B) Incorporating comes with an increase in liability compared to other business structures.
C) The regulations will be more burdensome than in other business structures.
D) The corporation will only last as long as she is able to work
A valid concern that Amelia might have is C. The regulations will be more burdensome than in other business structures.
A corporation refers to an organization that is authorized to act as a single entity. A corporation is a legal entity and is distinct from its owners.
It should be noted that under law, corporations can loan and borrow money, enter contracts, sue, own assets, etc. The purpose of a corporation is to make a profit.
The concern for Amelia will be the fact that a corporation is highly regulated. It's usually monitored by government agencies. There are also regulations that are put in place in order to protect the rights of employees. Therefore, this may be a challenge for Amelia since she may not have the freedom like that of a sole proprietor.

Why lapse in managing supplier can tarnish the buyer's reputation?
Answer:
yep
Explanation:
notthing
The lapse in managing suppliers causes buyer shortages or the sale of poor quality products that cause customer dissatisfaction and tarnish the buyer's reputation.
We can arrive at this answer because:
Buyers are companies and stores that buy products or materials from suppliers to supply them to customers.Buyers and suppliers have a very well-established business relationship, as the success of buyers depends on good supplier management.Poor management causes suppliers to delay deliveries and provide poor-quality materials to buyers.These problems will be passed on to the customer, who will blame the buyer and could damage the buyer's reputation.In other words, we can say that the poor management of suppliers damages the buyer's reputation because this promotes poor service to the customer's needs, which will blame the buyer for these problems.

Since animal cells don’t have a cell wall, what would happen if they loss water indefinitely?
Answer:
Cells with a cell wall will swell when placed in a hypotonic solution, but once the cell is turgid (firm), the tough cell wall prevents any more water from entering the cell. When placed in a hypertonic solution, a cell without a cell wall will lose water to the environment, shrivel, and probably die.

Briefly summarize the main stages of human evolution beginning 410 million years ago with the evolution of amphibians.
Biologically, man is defined as primate by the species Hom.o sapiens, of which the only living subspecies is Hom.o sapiens sapiens. It is quite clear that man's closest living relatives are the African apes, chimpanzees and gorillas, and it is almost certain that chimpanzees are more closely related to us than to gorillas.
The early development of the human race took place in Africa. All fossils from our evolution from 7 million years ago to 2 million years ago that were found lived in Africa. Sometime almost 2 million years ago, however, human-like creatures of the genus Hom.o began to spread around the world, and fairly quickly populated large parts of Asia and Europe, all the way to Indonesia and China. Regarding the geographical origin of modern man, there are two main explanatory models.
According to the Out of Africa hypothesis, modern humans evolved in Africa and from there spread out over the world, competing with other hominids. The multiregional hypothesis instead claims that humans evolved in parallel from several at least partially isolated populations of hominids.
