The correct answer is C.production of white blood cells that can destroy disease-causing organisms as it protects the body against infection.
White blood cells guard your frame in opposition to contamination. As your white blood cells tour thru your bloodstream and tissues, they find the contamination and act as a military widespread to inform different white blood cells in their region to assist shield your frame from an assault of an unknown organism.
How are white blood cells produced in the skeletal system?White blood cells start withinside the bone marrow in a manner referred to as hematopoiesis. All blood cells descend from a not unusual place hematopoietic stem cell (HSC). This is likewise referred to as a "pluripotent" stem cell. These stem cells differentiate—or specialize—in distinctive stages.
Therefore it is clear that the production of white blood cells can destroy disease-causing organisms.

B. The planets would float off into space because without the sun inertia would no longer exist, and the planets would stop moving
forward.
C. The planets would float off into space because the gravitational force of the sun would no longer be there.
D. The planets would start crashing into each other because the forward motion of inertia would pull them toward each other.
Answer:
C. The planets would float off into space because the gravitational force of the sun would no longer be there.

If you can, visit a ranch! It would be best if you can create this project from what you experience on a ranch. If that is not possible, you can do your research on the Web.
If you are on or near a ranch, get permission to visit and spend time on the land, asking questions of the rancher(s) who run it. Some questions you will want to ask include:
What is the location and size of the ranch?
What kinds of ranch animals are there?
What kinds of wildlife are there?
How/where do they interact (water supplies, pastures, woods)?
What are the benefits to the land and water of the animals interacting?
How do the animals get along?
What predator problems do the ranchers face?
How do they protect from predators?
What fencing issues with wildlife are there?
What are the migration patterns of the animals?
What other things do the ranchers do with regard to wildlife management?
The finished product can be a written report (should be at least three pages, double-spaced, and include photos), or a presentation or video (make it at least four minutes long). If you can, take photos or videos (with permission).
If you are not near a ranch, do your research through videos and articles on the Web. Be sure to fully cite all your sources, and be sure that you have permission to use the information, photos, or videos. If you have personal experience with wildlife on ranchlands, add it to your report or presentation. Make it interesting, visual, and focused on how ranches and wildlife benefit each other, and include details of best-management practices that you encounter.

Answer:
The feasibility and profitability of game ranching have been amply demonstrated by a number of studies. The rationale behind advocating game ranching in Africa is that conditions in many parts of' the continent, whether resulting from inadequate rainfall or presence of certain disease organisms' are not appropriate for production of exotic cattle and other domestic stocks. Indigenous wild animal species on the other hand have evolved in the African ecosystem and are better adapted to the prevailing conditions and should therefore be more productive.
Game ranching is currently most developed in southern Africa (particularly South Africa Namibia and Zimbabwe), although a private game ranch, the Galana Ranch, was established in Kenya in the 1970s (King and Heath, 1975; Thresher, 1980). The ranch initially focused on three species: the fringe eared oryx, Oryx beisa callotis, the African buffalo and the eland. Reported advantages of the eland over the Boran cattle included much lower water requirement, faster breeding and growth, earlier maturity and ability to put on weight in grazing conditions under which the Boran cattle began to lose weight and approximately 14 % higher dressing out weight. In addition to these biological and physiological advantages a cost-benefit analysis of maintaining a breeding herd of 11,000 oryx and 5000 Boran on the ranch showed clearly that the financial returns on the oryx was far superior to that of cattle (Thresher, 1980).
Explanation:
I am not interested
Numerous studies have amply shown that game ranching is both feasible and profitable.
What is Argument?
The argument in favor of game ranching in Africa is that the climate in many regions of the continent, whether as a result of insufficient rainfall or the presence of specific disease organisms, is insufficient for the breeding of exotic cattle and other domestic species.
On the other hand, native wild animal species have evolved in the African ecosystem and are better adapted to the current conditions; as a result, they should be more productive.
Although a private game ranch, the Galana Ranch, was founded in Kenya in the 1970s (King and Heath, 1975; Thresher, 1980), southern Africa, particularly South Africa, Namibia, and Zimbabwe, currently has the most developed game ranching industry.
Therefore, Numerous studies have amply shown that game ranching is both feasible and profitable.

A geneticist is mapping the chromosomes of the newly captured gremlin. Stripe is heterozygous for three linked genes with alleles Bb, Ee, and Hh that determine if gremlins have biting teeth (B), are evil (E), and have hair (H). In order to determine if the three genes are linked, a standard testcross was done, and the 1000 offspring had the following genotypes: 48 bb ee Hh 36 Bb ee hh 400 Bb ee Hh 4 Bb Ee Hh 426 bb Ee hh 46 Bb Ee hh 38 bb Ee Hh 2 bb ee hh What is the recombination frequency between genes E and B
Answer:
The recombination frequency between genes E and B is 0.1 = 10%
Explanation:
Available data:
Cross: BbEeHh x bbeehh
F1) 1000 individuals in total
48 bb ee Hh 36 Bb ee hh 400 Bb ee Hh 4 Bb Ee Hh 426 bb Ee hh 46 Bb Ee hh 38 bb Ee Hh 2 bb ee hhTo know if two genes are linked, we must observe the progeny distribution. In a tri-hybrid cross, If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1:1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the heterozygote parent.
In the present example, the phenotypic ratio shows different proportions than the expected ones if they were not linked.
We can recognize the parental gametes in the descendants because their phenotypes are the most frequent, while the double recombinants are the less frequent. And simple recombinant gametes produced by the cross, which frequencies are intermediate.
Parentals:
400 Bb ee Hh 426 bb Ee hhDouble recombinants:
4 Bb Ee Hh2 bb ee hhSimple recombinant
48 bb ee Hh 36 Bb ee hh 46 Bb Ee hh 38 bb Ee HhComparing the parental and the double recombinant we will realize that they only change in the position of the alleles E/e. This suggests that the position of the gene E is in the middle of the other two genes, B and H, because in a double recombinant only the central gene changes position in the chromatid.
B------E------H
Now we will call Region I to the area between B and E and Region II to the area between E and H.
Once established the order of the genes we can calculate distances between them, and we will do it from the central gene to the genes on each side. First We will calculate the recombination frequencies, and we will do it by region. We will call P1 to the recombination frequency between B and E genes, and P2 to the recombination frequency between E and H.
P1 = (R + DR) / N
P2 = (R + DR)/ N
Where: R is the number of recombinants in each region, DR is the number of double recombinants in each region, and N is the total number of individuals. To calculate the recombination frequency, we have to know that 1% of recombinations = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.
So:
• P1 = (R + DR) / N = 48 + 46 + 4 + 2 / 1000 = 100/1000 = 0.1
• P2 = (R + DR)/ N = 36 + 38 + 4 + 2 / 1000 = 80/1000= 0.08
Now, to calculate the recombination frequency between the two extreme genes, B and H, we can just perform addition or a sum:
P1 + P2 = Pt
0.1 + 0.08 = Pt
0.18 = Pt
The genetic distance will result from multiplying that frequency by 100 and expressing it in map units (MU). One centiMorgan (cM) equals one map unit (MU). The map unit is the distance between the pair of genes for which one of every 100 meiotic products results in a recombinant product.
• P1 = 0.1 x 100 = 10%
• P2 = 0.08 x 100 = 8%
• Pt = 0.18 x 100 = 18 %
1) Explain why a high concentration of salts in the soil tends to reduce transpiration.
2) explain why seedlings have a better chance of survival when transplanted in the evening.
Answer:
The absorption of water by the roots of plants is through the osmotic gradients between the soil and the plants xylem vessels.
The high the osmotic gradients the faster the water uptake though the sieve tubes in the plants. The movement of water from the soil into the roots is by osmosis and root pressure.
In a normal soil Osmosis is the movement of water molecules from the region of higher water potential(soil) to the region of lower water potential(plant roots) though a semipermeable membrane.
Therefore a soil with high salt concentration the higher salt would affect the osmotic potential and few water molecules would be able to move from the roots into the roots. This is because the more salt molecules reduced the water potential for water molecules to move through the root by the root pressure initiated by osmosis to form transpiration pull and stream in stems.
Since the loss of water in transpiration comes from water absorbed by the roots through osmosis, root pressure ,transpiration stem and pull, ,the reduced absorbed water leads to reduced transpiration.
2.
The loss of water from the leaves is through stomata. These are usually open for water loss by transpiration .During evening they are close. Therefore transpiration stream amd pull do not take place, so little water absorbed from the soil and water s conserved in plants.
Thus transplant done during the evening gives the seedlings chances of survival because the closed stomata ensues waters conservation, and less stress on the roots which prevent transpiration through the stomata..

What is Petrified fossils?Petrified fossils are formed when minerals replace all or some part of once-living matter.
Petrified fossils result from a process known as permineralization which occurs when ground water solutions containing iron, carbonates, silicates or other minerals seeps through the remains of buried organisms (plants or animals).
When the water evaporates, the minerals remain and replace the organic matter to form a petrified fossil. This method preserves the most detail of an organism because it greatly retains the appearance of organisms.
