A prokaryote that obtains energy from light is a Phototroph.
Phototropic bacteria or archaea are a group of prokaryotes which use the source of energy as light. These prokaryotes convert the light energy to chemical energy in the form of chemical bonds and have several photochemical mechanisms in their metabolic pathways. Depending on the metabolic pathway the bacteria follow, the phototropic prokaryotes use carbon sources and are autotrophs undergoing the process of photosynthesis.
The cyanobacteria are the most commonly known prokaryotes which are phototropic in nature.
What determines the nucleotide sequence of the newly synthesized strand during dna replication?
During replication, the nucleotide sequence of the newly synthesised DNA strand is determined by the template strand of the parent DNA. From the 5' end to the 3' end, DNA is synthesized.
What is DNA replication?DNA replication is a process in which a copy of the DNA is synthesised from the parent DNA. In the DNA synthesis, both strands are separated by the helicase enzyme.
This enzyme unwinds the double strand of DNA and converts it into a single strand. The single strand is taken as a template by the DNA polymerase. The DNA polymerase synthesises the new DNA by adding the nucleotide from 5' to 3'.
The 3' OH of the existing nucleotide is attached to the 5' phosphate of the upcoming nucleotide by making a phosphodiester bond. Adenine pairs with thymine, and guanine makes a pair with the cytosine base during DNA replication. These are nitrogenous bases.
Hence, the existing nucleotide bases of parent DNA strands make new strands complementary.

Which of the following describes an interaction between the musculoskeletal system and the respiratory system?
The air sacs absorb more oxygen during vigorous exercise.
The air sacs are used due to signals from the brain.
The blood delivers glucose and oxygen to cells.
The blood carries waste materials to the kidneys.
PLEASE ANSWER QUICK
Answer:
The air sacs absorb more oxygen during vigorous exercise.
Explanation:
Function of respiratory system is to carry out gaseous exchange to makes the blood rich in oxygen. Musculoskeletal system is involved in movement of body and needs oxygenated blood to drive the muscle contraction and body movements. Musculoskeletal system needs increased oxygen supply during vigorous physical activity to support the movement which in turn is fulfilled by increased absorption of oxygen by air sacs.

Proteins are made from what subunits?
Proteins are created from subunits called amino acids, which join together through peptide bonds. The structure and function of a protein is determined by the unique combination and interactions of these amino acids. Hemoglobin is a notable example of protein structure.
Explanation:Proteins are important components for all body tissues, and they are made from subunits called amino acids. These amino acids are nitrogen-containing monomers that join together by peptide bonds. The structure and function of proteins largely depends on their shape, which in turn is determined by the interactions between these amino acids and their subsequent folding into various secondary, tertiary, and quaternary structures.
There are 20 different types of amino acids that contribute to the thousands of different proteins in the human body. Each protein contains a unique combination of these amino acids.
An example to demonstrate this concept is hemoglobin, a protein that has a quaternary structure made up of four globular protein subunits: two alpha and two beta polypeptides.

A race car driver loses his leg in an accident. Apply Lamarck's and Darwin's theories of evolution to predict whether this disability will be carried forward by his children.
Answer:
According to Lamarck's theory the mutation in the somatic cells would also be carried from the parents to the children.
But, Darwin's theory states that the somatic mutations are not carried to another generation. Only germ line mutations are carried from one generation to another.
Since, losing a leg during leg injury is not related to germ line so it would not be carried from parent to children.
This statement is true according to Darwin but false according to Lamarck's theory.
In humans, a cleft chin is dominant and no-cleft is recessive. What will the generations look like? Assume that Mendel’s method of crossing two true breeding parents with opposite traits is followed. Check all that apply.
The P generation, F1 generation, and F2 generation will have all cleft chins.
The P generation, F1 generation, and F2 generation will have all no-cleft chins.
The P generation and F1 generation will have all cleft chins.
The F1 generation will have all cleft chins.
The P generation and F2 generation will have all no-cleft chins.
The P generation and F2 generation will have cleft chins and no-cleft chins.
The P generation, F1 generation, and F2 generation will have cleft chins and no-cleft chins.
The answers would be:
The F1 generation will have all cleft chins.
The P generation and F2 generation will have cleft chins and no-cleft chins.
If you'd like to know why:
Using Mendel's method of crossing:
Let C be the dominant trait and c be the recessive trait.
We do first the P generation. True breeding would been that both are homozygous, one is dominant and the other recessive.
CC x cc (This means in the P generation, we have both no cleft chins and cleft chins)
The Punnet for that would look like this:
c c
C Cc Cc
C Cc Cc
F1 generation would then all have cleft chins. If the genotype of the same trait consists of at least 1 dominant allele, then the dominant trait will be expressed. In this case, cleft chin.
Now we do the breading of F1 generation. So since they are all Cc, then the cross would be between two Cc.
Cc x Cc (F1 Generation)
The Punnet for that would look like this.
C c
C CC Cc
c Cc cc
As you can see we have a homozygous recessive in the mix now and the others are all dominant. So we can say that the F2 generation is a mix of cleft- and no cleft chin.
The generations will look like the following:
The F1 generation will have all cleft chinsThe P generation and F2 generation will have cleft chins and no-cleft chins.According to this question, a gene coding for presence of cleft is involved. The allele for cleft chin (C) is dominant and no-cleft (c) is recessive. If two true breeding parents are crossed i.e. CC (cleft chin) × cc (no cleft chin) (see attached image). The F1 generation consists of offsprings with Cc genotype. If Cc × Cc are crossed to get the F2 generation, the following offsprings are produced: CC, Cc, Cc and cc. CC will have a cleft chinCC will have a cleft chincc has no cleftTherefore; the generations will look like the following:

commercial jets fly in the lower stratosphere. what happens to thhe exterior temperature of these planes as they leave the stratosphere and return to the ground
As a jet transitions from the stratosphere back to the troposphere and ultimately to the ground, the exterior temperature of the plane increases due to higher air density and increased heat absorption in the lower atmosphere levels.
Explanation:
When a commercial jet transitions from the lower stratosphere back to the troposphere, the exterior temperature of the plane increases. In the troposphere, where most of our weather occurs, temperatures rise as it approaches the Earth's surface. This is due to the higher density of air and its ability to absorb and retain heat. The stratosphere above is generally colder and lacks the defining weather characteristics we see near ground level.
As the plane descends from the stratosphere to the troposphere, the increase in temperature is notably due to the fact that the stratosphere's temperature increases with altitude because of the ozone layer's absorption of the Sun's ultraviolet radiation. However, the overall trend still shows a significant decrease in temperature as we climb from the Earth's surface to the upper levels of the stratosphere, thus when the plane returns to ground, it experiences an increase in the exterior temperature.

One species of fish feeds in the muddy bottom of a lake. a second species eats insects that land on the water surface. this is an example of
Final answer:
The example given is a demonstration of ecological niches and resource partitioning, where two fish species have different feeding habits that reduce competition for food resources, an instance of disruptive selection and assortative mating contributing to species divergence.
Explanation:
The scenario presented where one species of fish feeds in the muddy bottom of a lake, while a second species eats insects landing on the water surface, illustrates the concept of ecological niches and resource partitioning. In the context of ecology and evolutionary biology, these behaviors reflect how species utilize different parts of their environment to avoid direct competition for resources – a phenomenon known as disruptive selection. This form of ecological divergence often leads to species developing specialized feeding habits and adaptations.
Disruptive selection and assortative mating are important mechanisms contributing to the formation of new species within ecosystems. As species evolve to exploit different resources, they may also exhibit preferences in mating with individuals that have similar resource usage patterns, further contributing to the divergence of species. The example of the three-spined stickleback fish described by Dr. Luke Harmon's research highlights how variations in feeding habits could lead to evolutionary changes that impact the ecosystem environment.
