5 0

A hypothesis is an educated guess. This is part of the scientific method developed in science to explain natural phenomena in the environment. Usually scientists use the hypothesis in their controlled experiments.

Whether it is a fact or not scientists use the hypothesis as a basis or a starting point for further explanations. This is known as the scientific hypothesis. When an educated guess yields the same results over time, the answer is called a theory. Something that is widely accepted but still needs to be proven and investigated further.

In humans, the ABO blood type is under the control of autosomal multiple alleles.Color blindness is a recessive X-linked trait.M

kifflom [539]

Answer: 1/4

Explanation:

Firstly, in order for both parents to be type A and have children with type o blood, their blood types must both be Ao. Since o is a recessive blood type, a punnett square shows there is a 25% chance any child of theirs will have type o blood. If neither parent is color blind and they have a son who is, it implies that the mother is a carrier of colorblindness and has the genotype XᴮXᵇ. If you do a punnett square of the not colorblind father (XᴮY) and the mother, it shows that a daughter would have a 0% chance of being colorblind. Therefore colorblindess is irrelevent, since there is no possibility of the daughter not having normal color vision. In conclusion, there's a 25% chance she will have type o blood and not be colorblind, since the other 75% chance would be having type A blood and not being colorblind.

Based on your knowledge of ocean chemistry, predict the feeding mode and size of organisms found in the deep layers of the ocean

ASHA 777 [7]

In the deep layers of the ocean, various distinct kinds of species are found like fangtooth fish and vampire squid, to sea urchins and coffinfish.

One of the probable adaptation, which is not fully understood in the deep sea is gigantism. This refers to the ability of animals to become highly enormous in size. A well-known illustration is a giant squid, and others, like giant isopod, the kings of herrings selfish, and the colossal squid.

One of the possible reason of gigantism is the tendency of the species in the deep sea to live for long years, that is, for decades or for even centuries. As food is not abundant in the deep zones, thus deep sea creatures have evolved some interesting mechanisms of feeding.

In the non-existence of photosynthesis, the majority of food comprises of detritus, that is, the decaying leftovers of algae, microbes, animals, and plants from the upper layers of the ocean. Apart from that, the corpses of large animals, like whales that sink to the bottom give irregular but huge feasts for deep-sea animals.

We are studying 3 strains of bacteria, with populations p1, p2, p3, in an environment with three food sources, A, B, C. In a day

Nastasia [14]

Answer:

The population of each bacteria in 1, 2, 3 are 12, 8, and 7 respectively.

Explanation:

From the given information:

For food source A; we have:

3P₁ + P₂ + 2P₃ = 58 units of food A ---- (1)

For food source B; we have:

2P₁ + 4P₂ + 2P₃ = 70 units of food B ---- (2)

For food source C; we have:

P₁ + P₂ = 20 units of food C ----- (3)

From equation (1) and (2); we have:

3P₁ + P₂ + 2P₃ = 58

2P₁ + 4P₂ + 2P₃ = 70

By elimination method

3P₁ + P₂ + 2P₃ = 58

2P₁ + 4P₂ + 2P₃ = 70

P₁ = -12 + 3P₂ ---- (4)

Replace, the value of P₁ in (4) into equation (3)

P₁ + P₂ = 20

-12 + 3P₂ + P₂ = 20

4P₂ = 20 + 12

4P₂ = 32

P₂ = 32/4

P₂ = 8

From equation (3) again;

P₁ + P₂ = 20

P₁ + 8 = 20

P₁ = 20 - 8

P₁ = 12

To find P₃; replace the value of P₁ and P₂ into (1)

3P₁ + P₂ + 2P₃ = 58

3(12) + 8 + 2P₃ = 58

36 + 8 + 2P₃ = 58

2P₃ = 58 - 36 -8

2P₃ = 14

P₃ = 14/2

P₃ = 7

Thus, the population of each bacteria in 1, 2, 3 are 12, 8, and 7 respectively.
