Answer 1
Question:-

Which factor least influences the rate of photosynthesis?

Options :-

A) Atmospheric concentration of carbon dioxide

B) Time of day

C) Number of chloroplasts

D) Concentration of nitrogen in the air

Answer :-

D) Concentration of nitrogen in the air

Explanation :-

Concentration of nitrogen in air is about 78% and it's insert in nature bez neither the planets nor the animals have the ability to break three bonds of N2 molecule (gas ) so any alterations in its concentration will not make any influence in photosynthesis concentration of CO2 make influence in the maximum but it also makes its effect upto some extent and that extent is called the saturation point Time of the day is effects like in morning and Evening photosynthesis is very less in comparison to the photosynthesis in afternoonRate of photosynthesis is directly proportional to number of chloroplast as more the number of chloroplast more will be the photosynthesis
Answer 2

The factor that least influences the rate of photosynthesis is the Concentration of nitrogen in the air. Thus, the correct option for this question is D.

What is Photosynthesis?

Photosynthesis may be defined as a type of process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.

The process of photosynthesis significantly depends on the amount and color of sunlight along with the amount of carbon dioxide because they are the reactants of this reaction while the amount of sugar is delivered as a product of the reaction.

Therefore, the factor that least influences the rate of photosynthesis is the Concentration of nitrogen in the air. Thus, the correct option for this question is D.

En una situación experimental, tras permanecer en ayunas, tres personas ingieren: la primera (A) una ración de celulosa, la segunda (B) una ración de glucosa y la tercera (C) una ración de almidón. Compare la rapidez con la que suba la glucemia (nivel de glucosa en sangre) de las tres personas. Razone la respuesta.

Answers

Answer:

La respuesta correcta es: "El orden de rapidez en el sube la glucemia es el siguiente: (B) una ración de glucosa, (C) una ración de almidón y (A) una ración de celulosa".

Explanation:

La rapidez a la que sube el nivel de glucosa en la sangre depende del alimento que estemos ingiriendo. En este caso, el ingerir una ración de glucosa será lo que aumente el nivel de glucemia más rápidamente dado que no requiere ningún procesamiento digestivo. En segundo lugar será el almidón, el cuál debe ser degradado por la enzima amilasa para tener acceso a la glucosa. En último lugar será la celulosa, dado que no tenemos las enzimas necesarias para digerirla y se requiere la ayuda de microorganismos para hacerlo.

What are two ways that different species can divide up resources?

Answers

Answer:The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources). Two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.

Explanation:hope this helps happy hallowen

A group of scientists determines that a mitochondrial DNA sequence shared by two species has a constant mutation rate. The sequences of mitochondrial DNA for the two species are shown below. Species A: GACTGGGCATTA Species B: GACCGGACATTA Based on this information, which of the following best explains the difference in the DNA sequence between the two species? Species A and B probably share the most recent ancestor because they only differ by three mutations. Species A and B have fewer differences between DNA sequences means that fewer mutations occurred. Species A and B probably have distinct ancestors because they have many differences in mutations. Species A and B are closely related because they differ by five mutations in their DNA sequence.

Answers

Species A and B have fewer differences between DNA sequences means that fewer mutations occurred. It is likely due to sequence homo-logy.

Whta are mutations?

A mutation is any alteration in the nucleotide (DNA) sequence of the genome of a particular organism.

The linear order of nucleotides and their differences (mutations) can be used to infer homo-logy between two species.

In this case, there are only two different nucleotides in these sequences, thereby sequence homo-logy indicates a likely common origin.

The coefficient of viscosity of blood is directly proportional to the frequency of interactions of erythrocytes with the vessel walls. As blood enters small vessels, many erythrocytes tend to flow in the center of the vessel. Given this information, which graphic best describes the effect of vessel diameter on the coefficient of viscosity?.

Answers

The coefficient viscosity is the resistance for blood to flow. There is a direct relationship between vessels diametre and viscosity. In the attached files it is the graph that best describes this relationship.

What is blood viscosity?

Viscosity is the property of fluids to resist the tangential displacement of molecule layers.

Blood viscosity refers to the resistance for blood to flow. Blood viscosity depends on the blood density and the vessel diameter.

Viscosity increases when the number of blood cells increases and when more cells get in contact with vessels walls.

The more viscose is in the blood, the greater resistance there is to move it, and the more blood pressure it requires to flow through vessels.

Viscosity decreases when blood velocity increases.

According to this framework and to the problem statement, we could assume that

smaller vessels ⇒ faster flow ⇒ less wall resistance → less vistositybigger vessels ⇒ slower flow ⇒ more wall resistance → more viscosity

In smaller vessels, blood flow is greater and more cells move in the center, leading to fewer cells interacting with walls. There is higher pressure and less resistance for blood to flow.  

In bigger vessels, blood flow is slower, and more cells are interacting with each other and with the vessel walls. There is lower pressure and more resistance for blood to flow.  

Since the coefficient of viscosity is directly proportional to the frequency of interactions of erythrocytes with the vessel walls, we can assume that blood flowing through bigger vessels express a higher coefficient of viscosity than blood flowing through smaller vessels.

In the attached files you will find an image representing the relationship between the coefficient of viscosity and vessel diameter.

You should compare this image with your images and choose the correct one.
