Answer:

Osmoregulation is a process that regulates the osmotic pressure of fluids and electrolytic balance in organisms. In animals, this process is brought about by osmoreceptors, which can detect changes in osmotic pressure. Humans and most other warm-blooded organisms have osmoreceptors in the hypothalamus. Besides the brain, osmoregulators are also found in the kidneys..

Explanation:

1.No, due to global warming the rise in temperature will slowly vaporises the water from oceans.On the other hand, the tectonic plates and the decrease of water level from water resources leads to the unification of land in a fixed way.

2.As tectonic plates are much located inner the earth than we expected.And, the earth is huge so we can't see small changes occuring through natural phenomena

Answer:

The rate of fermentation can be measured by placing a small amount of yeast and sugar solution in a fermentation tube. ... The fermentation rate of the yeast can be calculated by measuring the volume of CO2 at the top of the tube and dividing it by the amount of time it took for that volume to form

Answer:

Penicillin, direct

Explanation:

this scientist has to inoculate the parent population using plates that contains penicillin in them. we call this approach the direct selection.

In the direct selection, bacteria is grown on a material that has penicillin in it. the goal is to find mutants that have resistance to penicillin. only these resistant ones would grow and then a direct identification would be done.

Answer:

C flagella and cilia are the answer

The tubulin protein is a major component of flagella and cilia. The correct option is C.

In molecular biology, the term "tubulin" can refer to either the tubulin protein superfamily of globular proteins or one of its constituent proteins. Microtubules, a crucial part of the eukaryotic cytoskeleton, are created when - and -tubulins polymerize.

Highly conserved - and -tubulin heterodimers produce dynamic microtubules that carry out a variety of vital cellular tasks, including force generation during cell division, structural support, and transport route. Two polypeptide subunits make up tubulin, and dimers of these subunits connect to form protofilaments, which are very long strands.

Therefore, the correct option is C. flagella and cilia.

Answer:

1. The overall chemical equation of the light-dependent reactions is given below:

12 H₂O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll ----> 6 O₂ + 12 NADPH + 18 ATP

2. The overall chemical equation for the light-independent reactions of the Calvin cycle is given below :

3 CO₂+ 6 NADPH + 5 H₂O + 9 ATP → glyceraldehyde-3-phosphate (G3P) + 2 H+ + 6 NADP+ + 9 ADP + 8 Pi

Explanation:

1. The light-dependent reactions convert light energy into chemical energy, producing ATP and NADPH which are used light-independent reactions to drive the synthesis of sugar molecules from inorganic CO₂ and water. Light-dependent reactions takes place in photosystem I and II. Photosystem I and Photosystem II ( PS I and PS II) are the two biochemical systems, active in chloroplasts, that serve as sites of electron transfer reactions in photosynthesis. Energy from sunlight is used to split water which releases electrons and hydrogen atoms which are transferred to NADP+ to produce ATP and NADPH and oxygen is produced as a waste product.

The overall chemical equation of the light-dependent reactions is given below:

12 H₂O + 12 NADP+ + 18 ADP + 18 Pi + light and chlorophyll ----> 6 O₂ + 12 NADPH + 18 ATP. Note that Pi refers to inorganic phosphate

2. The Calvin cycle refers to the light-independent reactions in photosynthesis. It occurs in three stages.

Stage 1 (Carbon fixation): In this first stage of the Calvin cycle, light-independent CO₂ is fixed by enzyme called ribulose bisphosphate carboxylase (RuBisCO) to ribulose bisphosphate (RuBP) to form glyceraldehyde-3-phosphate.

Stage2: ATP and NADPH are used to reduce 3-phosphoglycerate (3-PGA) into glyceraldehyde--phosphate (G3P). ATP and NADPH are used up in the process and are converted to ADP and NADP+, respectively.

Third stage: RuBP is regenerated, which enables the system to prepare for more CO2 to be fixed.

The overall chemical equation for the light-independent reactions of the Calvin cycle is given below :

3 CO₂+ 6 NADPH + 5 H₂O + 9 ATP → glyceraldehyde-3-phosphate (G3P) + 2 H+ + 6 NADP+ + 9 ADP + 8 Pi

Answer:

It is D

Explanation:

Trust me I've taken it already, and plus it talks about it not being in the water.

In the given instance, the ecological service which is providing the marsh is the water purification. Thus, the correct option will be D.

Ecological services or ecosystem services are the many and varied benefits which the humans are provided or get from the natural environment and the healthy ecosystems. Such ecosystems include, for example, the agroecosystems, forest ecosystem, grassland ecosystems, and also the aquatic ecosystems.

A group of researchers are monitoring the health of a salt marsh. They measure high levels of nutrients in the sediment but not in the water samples. In this instance, the ecological service which is providing marsh is the water purification.

Therefore, the correct option is D.

Humans breathe out carbon dioxside which plants need to live and grow during the process of photosynthesis.

Explanation:

They do this by a process known as photosynthesis. ... Photosynthesis and respiration are the two essential processes that allow life to sustain on earth. In a way, they are a cycle — plants help humans breathe by providing us with oxygen, and humans help plants "breathe" by providing them with carbon dioxide.

Ecological and ethological approaches to the study of behaviour. The natural history approach of Darwin and his predecessors gradually evolved into the twin sciences of animal ecology, the study of the interactions between an animal and its environment, and ethology, the biological study of animal behaviour.

Answer:

The answeer is both B and D.

Answer: The presence of the polygenic trait masks the other possible alleles involved. There are only two possible phenotypes for the trait. The graphing of the possible phenotypes results in a bell curve. Usually, traits are polygenic when there is wide variation in the trait. For example, humans can be many different sizes. Height is a polygenic trait, controlled by at least three genes with six alleles. If you are dominant for all of the alleles for height, then you will be very tall.

Explanation:

Amoeba can move via the extension of finger-like projections called pseudopodia, what prevents plant cells from moving in the same fashion?

Ans: The plants that prevent the information of pseudopodia have rigid cell walls. which is unlike to amoeba.  

How does the euglena compare to both plant and animal cells (i.e. - explain what structure(s) might make it similar to plants and what structures might make it similar to animals).

Ans: Euglena are similar to plants because they both have chloroplast and are similar to animals because  neither has a cell wall.
