what do the term phycobiont and mycobiont signify ?
Answer:
Phycobiont refers to the algal component of the lichens and mycobiont refers to the fungal component. Both of these are present in a symbiotic relationship in which algae prepare food for fungi due to the presence of chlorophyll whereas the fungus provides shelter to algae and absorbs water and nutrients from the soil.
Explanation:
Elements of xylem in a vascular bundle are lesser than those of phloem؟
Answer:
No.
Explanation:
No, elements of xylem in a vascular bundle are not lesser than those of phloem because of the division of xylem progenitor cells that increases the xylem concentration in vascular bundle. The vascular cambium forms more xylem tissue than phloem due to more division of the xylem progenitor cells. so in the light of this discussion we can say that xylem is more in concentration than phloem in a vascular bundle.

In humans blood type is determined by the A, B, and O alleles. The A and B alleles are codiminant to each other and dominant over the O allele. An individual with the AO genotype and an individual with the BO genotype can produce offspring with which of the following phenotypes.
O only
A or B only
A, B or O only
A, B, AB, or O
Please explain, also this is not a test its a test PREP
Answer:
D. A, B, AB, or O
Explanation:
We can start by visualizing all the possible genotypes of the offspring by drawing a Punnett square, which is a visual representation of the different possible combinations of alleles:
Individual 1 = AO, Individual 2 = BO
A O
B AB BO
O AO OO
Here we can see that there are 4 possible genotypes: AB, BO, AO and OO based on the alleles of the parents. Now we can match the genotypes to phenotypes to answer the question:
A and B are codominant, meaning that both will be expressed equally if both are present. Therefore the genotype AB will result in an AB phenotype.
Next, since A and B are both dominant over O, they are the alleles that will be expressed in the phenotype if paired with an O. This means that the genotype AO will result in an A phenotype, and likewise, genotype BO will result in phenotype B.
Finally in the genotype OO, although O is a recessive allele, there are no dominant alleles here to mask them, therefore O is expressed in the phenotype.
Hence, from the genotypes AO and BO, the possible offspring genotypes are AB, BO, AO and OO, translating to the possible phenotypes: A, B, AB or O.

which part of cellular respiration provide most of the energy to run
Answer: The electron transport chain.
Explanation:
Cellular respiration is defined as the mechanism by which living organisms converts organic substances from food such as glucose with the use of oxygen into energy-carrying biomolecules (e.g. adenosine triphosphate or ATP). There are different stages of cellular respiration which includes:
--> glycolysis,
--> pyruvate oxidation,
--> the citric acid or Krebs cycle, and
--> oxidative phosphorylation.
The oxidative phosphorylation also referred to as the ELECTRON TRANSPORT CHAIN occurs in the inner membrane of the mitochondria. It transfers electrons donated by the reduced electron carriers NADH and FADH2 (obtained from glycolysis, the citric acid cycle or fatty acid oxidation) through a series of electrons acceptors, to oxygen.
The electron transport chain is said to produces most of the energy which is 34 ATP molecules, as compared to only 2 ATP for glycolysis and 2 ATP for Krebs cycle.
What types of food molecules make up chicken? (Carbs, Proteins, and/or Fats?)
no links!!
but its fats right??
Answer:
Fats
Explanation:
Chicken contains many different amino acids with different R-groups. In particular, chicken contains a large number of Tryptophan amino acids, which are amino acids that contain the side chain known as “indole”.
The type of food molecules that make up chicken is Proteins. It generally contains about 20% of proteins.
What do you mean by Food molecules?Food molecules are those which give energy to living organisms and contain chemicals that are required for the growth and repair of cells and their functions in the body of living organisms.
Proteins are the polymers of amino acids, which are linked via peptide bonds. The side chains of amino acids are varied from one to another. These side chains provide stability to the amino acid sequence. Mostly, the side chain of tryptophan and arginine gives the makeup to the food molecules of chicken.
Therefore, the type of food molecules that make up chicken is Proteins.

Which two conditions do most seeds need in order to germinate?
A. Adequate sunlight
B. Enriched soil
C. Adequate water
D. Warm temperatures
Answer:
I believe it is a and c because plants need sunlight and water
Explanation:
The correct answer of the question about seed germination is that Adequate water and Enriched Soil are the two most important condition in order to germinate seed.
What do you mean seed germination?The fundamental process by which many plant species develop from a single seed into a plant is known as seed germination. This method has an impact on crop output and quality.The growth of a seedling from an angiosperm or gymnosperm seed is a frequent example of seed germination.Rapid water uptake by the seeds during the early stages of germination causes swelling and optimal temperature induced softening of the seed coat. Imbibition is the name given to this phase. Enzymes are activated to begin the growth process. The seed starts to create proteins, respire, and metabolise the food that has been stored after activating its internal physiology. This is the lag phase of seed germination.The seed coat bursts, allowing the radicle to emerge and develop into a main root. The seed begins to take up water from underground. After the radicle and plumule have emerged, the shoot begins to ascend.The seed cell lengthens, divides, and becomes metabolically active in the last stage of seed germination to produce the seedling.
Thus, we can conclude that after analysing and understanding the above given theory the best two realistic conditions in order to germinate good quality of seeds can be that Soil should be enriched and Adequate water supply should be there.

In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. What percentage of offspring are expected to be chestnut?
Answer:
This question is incomplete, the complete question is as follows:
- In horses, black coloring (B) is dominant, and chestnut coloring (b) is recessive. A homzygous black horse crosses with a chestnut horse.
What percentage of offspring are expected to be chestnut?
The answer is 0%
Explanation:
This question involves a gene coding for color in horses. The allele for black coloring (B) is dominant over the allele for chestnut coloring (b) is recessive.
According to this question, if a homzygous black horse (BB) crosses with a chestnut horse (bb), the following gamete will be produced by each parent;
BB - B only
bb - b only
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
Bb, Bb, Bb, Bb
All of these offsprings are phenotypically black colored although heterozygous in genotype. Hence, 0% of offspring are expected to be chestnut.

Choose the items that complete the sentence about the key features of f(x) = 8x. The y-intercept is Choose... , the asymptote is y = Choose... , and the range is y > Choose... .
Answer:
I suppose that the equation is:
f(x) = 8/x
(You wrote 8x, this is a linear function, so it has no asymptotes, then I assume that the actual function was 8/x)
The y-intercept is the value such that f(x) = 0
Notice that there is no value of x such that 8/x = 0 (if the numerator is never zero, then the quotient can't be zero)
So we do not have an y-intercept.
The asymptote:
Here we have four:
if x tends to zero from the negative side, then:
8/x tends to negative infinity.
if x tends to zero from the positive side, then:
8/x tends to positive infinity.
These two asymptotes can be written as:
[tex]\lim_{n \to \_-0} \frac{8}{x} = -\infty\\ \lim_{n \to \_+0} \frac{8}{x} = +\infty[/tex]
We also have two when x tends to plus infinity (and 8/x goes to zero) and when x tends to negative infinity, such that the function tends to zero again, these two can be written as:
[tex]\lim_{n \to \infty} \frac{8}{x} = 0\\ \lim_{n \to -\infty} \frac{8}{x} = 0[/tex]
Finally, the range:
The only value that y never reaches (only on limits) is:
y = 0
Then the range is the set of all real numbers except the zero, or:
R : { x ∈ R / {0} }
Air at the equator is warm and has a ______density, which creates ________ in comparison to the air at the poles.
Answer:
Lower, low pressure
Explanation:
The temperature at equator are mostly higher than at the poles almost all times of year. This high temperature causes air at the equator to warm up quickly and thus, the air density reduces and it becomes lighter. Now, light air rises upwards. Thus, creating a low pressure region at equators. This low pressure causes the air near the poles gush towards the equator.
Hence, the blanks will be filled with the words
Lower, low pressure.

What concept does Hubble's Law most concern?
A. energy lost over time across the universe
B. growing distance between galaxies
C. how stars recycle energy and matter
D. how the universe will eventually end
Hubble's Law most concern with growing distance between galaxies. Thus option B is correct.
What is Hubble's Law ?Hubble’s law refers to the observation in physical cosmology where the movement of galaxies from the Earth at a speed that are proportional to their distance.
The velocity of the galaxy which is called as the redshift.
This laws study physical cosmology and is also known as Hubble-Lemaitre law.
After measuring recession velocity one can determine the distance of the galaxy from us by using Hubble’s equation.
Some limitations are; due to intrinsic motion of galaxies, observed velocity gets influenced and Galaxy orbit due to gravitational movements.
Hubble constant is another unit of measurement, which is used for description of the expansion of the universe. It is 160 km/s per million-light-years.
Thus option B is correct.

Sophia discovered two objects in space with the help of her telescope. She noted down the characteristics of the objects in the chart below.
Which of these statements is most likely correct about Object 1 and Object 2 discovered by Sophia?
A. Object 1 is an inner planet and Object 2 is a comet.
B. Object 2 is an inner planet and Object 1 is a comet.
C. Object 1 is an outer planet and Object 2 is an asteroid.
D. Object 2 is an outer planet and Object 1 is an asteroid.
Answer:
C. Object 1 is an outer planet and Object 2 is an asteroid.
Explanation:
While inner planets can have moons, many moons are a more common feature of outer planets (ex. Jupiter has 79 moons, while Mars has 2). Plus, moons don't orbit asteroids or comets since moons are usually larger. This rules out any of the options involving Object 1 being an inner planet, comet, or asteroid. As for object two, both an asteroid or a comet would make sense as they both have irregular shapes. The only answer that has Object 1 as an outer planet is C. Also Object 1 has rings, which shows that it's an outer planet.
