A certain eukaryotic organism has multiple, distinct genes with highly similar sequences that are expressed at different times in the organism's life cycle. these genes could have arisen by:________

Answers

Answer 1

These genes could have arisen by gene duplication.

What is gene duplication?

Gene duplication is the process of copying a section of DNA that codes for a gene. A retro transposition event or a recombination mistake are both potential causes of gene duplication. As a result, the duplicate gene coding may experience a significant number of modifications throughout time. This might prevent the gene from functioning or, in other situations, give the creature a benefit.

Gene duplication is a phenomenon that can happen through a variety of ways:

Ectopic Recombination: Uneven crossing-over between misaligned homologous chromosomes during meiosis might result in duplications. A duplication at the exchange site and a reciprocal deletion are the results of this recombination.Replication Slippage: Short genomic sequences can be duplicated as a result of the replication error known as replication slippage. DNA polymerase starts copying the DNA during replication, but eventually the polymerase separates from the DNA, causing replication to stall. The replicating strand is incorrectly aligned when the polymerase reattaches to the DNA strand, which accidentally results in several copies of the same portion.Aneuploidy: When a single chromosome's nondisjunction causes an abnormally high number of chromosomes, this condition is known as aneuploidy. Aneuploidy is frequently damaging and frequently causes spontaneous miscarriages in mammals. Some aneuploid people can survive. For instance, human trisomy 21 causes Down syndrome but is not lethal.

How does the size of the soil particles impact
the soil's permeability (movement of water)?

Answers

Answer:

Water moves by gravity into the open pore spaces in the soil, and the size of the soil particles and their spacing determines how much water can flow in. Wide pore spacing at the soil surface increases the rate of water infiltration, so coarse soils have a higher infiltration rate than fine soils.

How does soil particle size affect permeability?

But permeability is a different thing. It increases as particle size increases. By definition, permeability is a MEASURE OF EASE with which fluids will flow though a porous rock, soil or sediment. ... That means capillarity increase as particle sizes decreases.

Correct question: Write your question here (Keep it simple and clear to get the best answer). Define the term physiology?

Answer: physiology is the study of how the systems of the body works, and the ways in which their integrated cooperation maintains life and health of the individual.

Explanation:

The goal of physiology is to explain the physical and chemical factors that are responsible for the origin, development and progression of life. Each type of life, from the simple virus to the largest tree or the complicated human being, has its own functional characteristics.

In the study of the human physiology, we attempt to explain the specific characteristics and mechanisms of the human body that make it a living being. The very fact that we remain alive is almost beyond our control, for hunger makes us seek food and dear makes us seek refuge. Sensation of cold make us look for warmth.

Therefore in a simple term, PHYSIOLOGY is the study of how the systems of the body works, and the ways in which their integrated cooperation maintains life and health of the individual.

Answers

Answer:

Energy in the form of heat is released as chemical potential energy is transferred from glucose molecules to ATP molecules

The statement that best explains the movement of energy through aerobic cellular respiration is as follows:

Heat energy is released as chemical potential energy is transferred from glucose molecules to ATP molecules.

Thus, the correct option for this question is C.

What is Aerobic cellular respiration?

Aerobic cellular respiration may be defined as a type of biological process through which the molecules of glucose are broken down into carbon dioxide and water in the presence of oxygen with the liberation of some amount of energy. The derivation of energy is the fundamental mechanism of this process.

The mechanism initiate after capturing the heat energy from the and transforming it into chemical energy through the process of photosynthesis which synthesizes glucose. This glucose is then transferred to its potential energy to the ATP molecules in the presence of oxygen.

Therefore, heat energy is released as chemical potential energy is transferred from glucose molecules to ATP molecules. Thus, the correct option for this question is C.

How are ions such as phosphate absorbed by plant roots?

Answers

Plants absorb water from the soil by osmosis. They absorb mineral ions by active transport, against the concentration gradient. Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption.
Uptake occurs around the root tip, into epidermal cells with their associated root hairs and into cells in the outer layers of the root cortex.

Answer:

B. Geographically extinct

Explanation:

Lets take a moment to look at the words provided. Geographical means physical features of an area, or relating to geography. It can also relate to when we are talking about information on the Earth's surface. Extinct means that the organism is no longer alive, and that there are none left of its species. So, putting the two words together, geographically extinct means that the organism is no longer found on Earth.

the frequency of a wave in a stretched string depends on the length L, tension T and linear density m with dimension ML-1 . deduce the formula for f in terms of L , T and M using dimensional analysis​

Answers

Answer:

[tex]f = \frac{1 }{L}\sqrt{\frac{T}{m} }[/tex]

Explanation:

Let the frequency ,

[tex]f = L^{x}T^{y}m^{z}[/tex]

Now the unit of frequency is hertz = s⁻¹ = T⁻¹ where T is time, tension T = kgm/s² = MLT⁻¹ and linear density m = kg/m = ML⁻¹.

So,

[tex]T^{-1} = L^{x}[MLT^{-2} ]^{y}[ML^{-1} ]^{z}\\[/tex]

collecting the like bases, we have

[tex]T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ] \\L^{0} M^{0} T^{-1} = [L^{x + y -z}][M^{y + z} ][T^{-2y} ][/tex]

Equating powers on both sides, we have

x + y - z = 0  (1)

y + z = 0       (2)

-2y = -1         (3)

From (3), y = 1/2

From (2), z = -y = -1/2

Substituting y and z into (1), we have

x + y - z = 0

x + 1/2 - (-1/2) = 0

x + 1/2 + 1/2 = 0

x + 1 = 0

x = -1

So,

[tex]f = L^{x}T^{y}m^{z}\\f = L^{-1}T^{\frac{1}{2} }m^{\frac{-1}{2} }[/tex]

[tex]f = \frac{1 }{L}\sqrt{\frac{T}{m} }[/tex]

Impact on ozone appear to have on the amount of heat:

Since the majority of the atmosphere ozone has lies between the altitude of 20,000 m and 50,000 so here the temperature is increased so it should be within the altitude range.

On which side of the mountain would you be most likely to find a forest?

Answers

Answer:

Mountain lands provide a scattered but diverse array of habitats in which a large range of plants and animals can be found. At higher altitudes harsh environmental conditions generally prevail, and a treeless alpine vegetation, upon which the present account is focused, is supported. Lower slopes commonly are covered by montane forests. At even lower levels mountain lands grade into other types of landform and vegetation—e.g., tropical or temperate forest, savanna, scrubland, desert, or tundra.

The largest and highest area of mountain lands occurs in the Himalaya-Tibet region; the longest nearly continuous mountain range is that along the west coast of the Americas from Alaska in the north to Chile in the south. Other particularly significant areas of mountain lands include those in Europe (Alps, Pyrenees), Asia (Caucasus, Urals), New Guinea, New Zealand, and East Africa. The worldwide distribution of mountain lands is shown in Figure 1.
