2. C. A selectively permeable
membrane separates solutions A and B. The
concentration of water molecules in Solution
B is higher than that in Solution A. Describe
how the water molecules will move.

3. A. How is active
transport different from passive transport?

3. B. What are transport proteins?

3. C. Explain why transport proteins
require energy to function in active
transport.

Answers

Answer 1

Answer:

1. Water(solvent) molecules travel from A across the cell membrane / semi permeable membrane to B until the concentrations of A and B become equal.2. Active transport moves molecules and ions from lower concentration to higher concentration with the help of energy in the form of ATP. On the other hand, passive transport moves molecules and ions from a higher concentration to lower concentration without any energy.3. A transport protein is a protein that serves the function of moving other materials within an organism. 

4. Active transport is the movement of materials through a cell membrane using cell membrane using cellular energy. ... transport proteins requires energy to function because it needs energy then passive transport that requires no energy at all.

Assume that producers in an ecosystem have 1,000,000 kilocalories of energy. How much energy is available to primary
consumers?
5. Which trophic level has the greatest biomass?

Answers

Assuming that producers in an ecosystem have 1,000,000 kilocalories of energy, 100,000 Kilocalories of energy would be available to primary consumers.Producers is the trophic level with the greatest biomass

HOW IS ENERGY TRANSFERRED:In a food chain, energy is being transferred when one organism in a particular trophic level feeds on another organism in a lower trophic level.

The lowest trophic level contains the producers, which are organisms that start the food chain. However, only about 10% of energy is available to the organism in the next trophic level as 90% is lost as heat.

Therefore, according to this question, if it is assumed that that producers in an ecosystem have 1,000,000 kilocalories of energy; 10/100 × 1,000,000 = 100,000 kilocalories of energy will be available to primary consumers.

WHAT IS BIOMASS:The total biomass of an organism in each trophic level decreases going up. This is due to the lesser energy transferred from one trophic level to the next.

As the trophic level increases, lower energy is available to convert into biomass. Hence, the higher the trophic level, the lower the biomass.

Therefore, if this is the case, the producers at the first trophic level will contain the greatest biomass which will decrease as the food chain progresses upwards.

What is currently happening with Mount Etna?

Answers

Answer:

As Italy’s National Institute of Geophysics and Volcanology (INGV) explains on a recent blog post, the nascent eruption began on the night of May 29. Starting off by producing a thick column of ash rising from the New Southeast Crater, it gave way on May 30 to a far more lava-heavy display in the area, featuring two fissures blenching out lava.

Answer:

There is currently no eruptive activity at the volcano involving fresh lava and monitoring signals do not suggest an immediate change likely; only a weak thermal anomaly continues to be present from the southeast crater complex.

A mother has one allele for dimples and one allele for no dimples. How many
of her gametes will carry the allele for dimples?

A. 0%
B. 25%
C. 100%
D. 50%

Answers

I am pretty sure that the answer is D.) 50%

Answer:

50%, i believe

Explanation:

So the mother in the problem must have gotten her alleles from her mother and father. Who donated what we are not sure. All we know is that she got one allele for dimples and one allele for no dimples. These are part of the mother's somatic cell DNA. This DNA is duplicated during interphase, right before meiosis occurs as the mother begins to form her gametes, however.

Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait
are called ______. A) phenotypes B) alleles
C) DNA
D) mutations E) genotypes

Answers

Answer:

The answer is B) alleles

Explanation:

Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait are called alleles.

What do you mean by traits?

Traits may be defined as the appearance or manifestation of the desired characters. Traits are also known as phenotypes.

Every factor or gene has two alternative copies, one comes from the father and one comes from the mother. These two copies are present in the same location on the homologous chromosome. They are known as alleles of each other.

Therefore, Alternate forms of a gene having the same position on a pair of chromosomes and affecting the same trait are called alleles.

Answers

Answer:

they can breed with one another, they have certain physical features in common, they evolved at the same rate, they live in the same ecosystem. Lions and house cats share common features, but cannot breed with one another.

Explanation:

They share a common ecology, they may breed with one another, share some physical characteristics, evolve at the same rate, and inhabit the same ecosystem, hence option D is correct.

What are the taxonomic classes?

If two species are members of the same class, they are also members of the same higher-level taxon. They share the same phylum and kingdom in this instance.

Kingdom, phylum or division, class, order, family, genus, and species are the seven main taxonomic ranks.

The taxon with the greatest number of species is the kingdom. In taxonomy, it is the broadest category into which the creatures can be divided.

The classification of five kingdoms was made by R.H. Whittaker. The kingdoms of Monera, Protista, Fungi, Plantae, and Animalia are included in this classification.

Therefore, option D is correct.

Allergy may be defined as a reaction by our immune system to something that does not trouble most other people. It affects a person more specifically.

When a person gets affected by any allergy, the immune system of that person may overreact by producing more antibodies. These antibodies attack the allergen particles and cause adverse symptoms.

A person who has allergies has them because his or her body over reacts to a material that would otherwise be ignored. It is an overreaction of the immune system triggering a immune attack response that is unneeded.

Therefore, a person who has allergies has a compromised immune system because the body's immune system overreacts to an antigen.
