What process adds carbon dioxide to the air?
Explanation:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

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.
Thus, option "4" is correct. .Compare the composition of the rock sample with other rock samples of known age.

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 would MOST LIKELY happen if the sun's gravitational pull no longer existed?
A. The planets would start crashing into each other because without the sun gravity would pull all of the planets together.
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.
Explanation:
I believe this is the answer because a sudden cease in the sun's gravitational pull would cause the planets to continue on a straight path in the direction the sun was pulling them before it ceased to exist.

As a result, some protists may share a closer relationship with plants, animals, or fungi than they do with other protists.
What is eukaryotic organism?Any eukaryotic organism (i.e., one whose cells include a cell nucleus) that is not an animal, plant, or fungus is referred to as a protist. Protists do not constitute a natural group, or clade, even though it is believed that they share a common ancestor with other eukaryotes (the last eukaryotic common ancestor).
As a result, some protists may share a closer relationship with plants, animals, or fungi than they do with other protists. However, the biological category protist is employed for practical reasons, much like the groupings of algae, invertebrates, and protozoans. Others define a protist as any unicellular eukaryotic microbe. Protistology is the study of protists.
Therefore, As a result, some protists may share a closer relationship with plants, animals, or fungi than they do with other protists.
