Are the seasons (summer or winter) the same in the Northern and Southern Hemispheres
at the same time? When it is summer in the Northern Hemisphere, what season is it in the
Southern Hemisphere?

Answers

Answer: No they don't occur at the same time

Summertime in the northern hemisphere happens when it is winter in the southern hemisphere, and vice versa.

The tilt of the earth causes the seasons. The northern hemisphere's summertime means that the northern part of the earth gets more sunlight compared to the southern half, so the southern half experiences winter.

With the tilt held at the same angle, the earth revolves to another point in space, so that the northern hemisphere receives less sunlight and the southern hemisphere gets more. So the seasons swap.

Answer: Winter

Explanation: The tilt of the Earth determines the seasons for the Northern and Southern Hemisphere. When the Northern Hemisphere tilts toward the Sun, it experiences summer. At the same time, the Southern Hemisphere tilts away from the Sun. It experiences winter.

What is the benefit of diversity in a gene pool?

increased chance of migration.
increased chance of equilibrium.
increased chance of extinction.
increased chance of survival.​

Answers

Answer:

Increased Chances of Survival

Explanation:

Genetic diversity we could say as Variation in a gene pool and it serves as a way for populations to adapt to changing environments, So if there is any environmental change, With more variation it more likely that some individuals will have variation of allele in them that suits the change so they will have brighter chances of surviving.  

An increased chance of survival is the benefit of diversity in a gene pool.

Increased Adaptability: A broad gene pool produces a population with a wider range of genetic features and variants. Due to this diversity, there is a greater chance that an individual may have favorable qualities that will allow them to adapt to shifting environmental factors like temperature, resource availability, or the prevalence of diseases. Individuals with genetic variants that are advantageous in the altered environment are more likely to survive and pass on their genes to succeeding generations.

Better Resilience: A diversified gene pool acts as a defense against potential dangers and difficulties. A population with a diverse range of genetic variations is more likely to have some members who are immune to or resistant to particular illnesses, predators, or other stressors.

Hence, an increased chance of survival is the benefit of diversity in a gene pool.

A. Cell theory.

Explanation:

The image above shows salamander skin cells as viewed under a microscope. The activity occurring inside the rectangle best supports a scientific theory known as cell theory with respect to cell division.

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Cell theory states that cell is the basic unit of life, all living organisms are made up of one or more cells and they typically arise from existing cells i.e pre-existing cells give rise to new ones through the process of cell division.

From the image of the salamander's skin cell, we can see that it comprises of many cells and are these look very much alike, meaning they are from pre-existing cells.

The most common chemical element present on our Earth is carbon. It has the symbol C and an atomic number of 6. The carbon atom is a member of the fourteenth group present on the periodic table.

The word carbon is derived from the Latin word 'carbo', which means coal. Carbon is also the 15th most abundant element that is present in the crust of the Earth. On the earth, carbon is the fourth most abundant element ranked after hydrogen, helium, and oxygen.

Carbon atoms, when bonded together in different ways,  are called as allotropes of carbon. Diamond, graphite, and amorphous carbon are the three allotropes of carbon.

They have different properties. Graphite is one of the softest known substances while diamond is the hardest known substance.

You have been studying the lysosomal enzyme cathepsin D in mammalian cells. To look at the localization of the enzyme, you incorporate 32 P into the cells over a long period of time and collect fractions of the cell lysate corresponding to various organelles. Much to your surprise, you find cathepsin D was isolated in the ER fraction, and it contains 32 positive sugar side chains. However, when you pass this enzyme through an affinity chromatography column containing mannose-6-phosphate receptor conjugated to resin, the enzyme passes straight through. However, your cousin calls you up and tell you that she modified your cell line. She claims that she deleted your endogenous cathepsin D gene and transfected a plasmid containing a cathepsin D gene with a Lys-Asp-Glu-Leu (KDEL) sequence on the C-terminus.a) Why is the lysosomal enzyme found in the ER fraction rather than in the lysosomal fraction?b) Explain why the modified enzyme does not bind to the mannose-6-phosphate receptor.

Answers

Answer:

Explanation:

1.

Cathepsin is involved in programmed cell death, it is a lysosomal enzyme and the reason it is found in the ER fraction instead of the lysosomal fraction is because of its c terminal KDEL sequence. this sequence ia a retrieval for protein and causes a backward movement of protein back to endoplasmic reticulum. that is why cathepsin seems to have localised in ER instead of the lysosomal fraction

2 It does not bind to mannose-6-phosohate receptor because this glycosylation process does not occur in the E.R but in Golgi bodies.  because of the KDEL sequence this glycosylation of cathepsin would not occur and cathepsin would go through affinity column without any form of  binding to receptor.If cathepsin can get to the Golgi then glycolysation with Mannose6phospate can occur.

What are the effects of ultraviolet radiation?

The experiment that ultraviolet light made plants grow more slowly is the experiment most likely has greater reliability in which the experiment repeated several times and each time found that plants grow slightly slower with ultraviolet rays because the experiment was repeated with the same.

The main effect of ultraviolet light on plant growth is during photosynthetic active radiation under high level, UV -B light increases the net plant photosynthesis in several plant species.

Higher production of dangerous radiation can be induced under both UV-B and high PAR in young and old plant leaves.When UV light is obtained by plants resins production increases and plant become richer in smelling and better in tasting.Due to increase in resin production the plant is protected  from pests and diseases.

The value of a share of common stock depends on the cash flows it is expected to provide, and those flows consist of the dividends the investor receives each year while holding the stock and the price the investor receives when the stock is sold. The final price includes the original price paid plus an expected capital gain. The actions of the marginal investor determine the equilibrium stock price. Market equilibrium occurs when the stock's price is -Select-less thanequal togreater thanCorrect 1 of Item 1 its intrinsic value.

Gordon who developed and popularized it. There are several conditions that must exist before this equation can be used.

In this situation, the equation is:Note that this is the same equation developed in Chapter 5 to value a perpetuity, and it is the same equation used to value a perpetual preferred stock that entitles its owners to regular, fixed dividend payments in perpetuity.

Most firms go through life cycles where they experience different growth rates during different parts of the cycle. For valuing these firms, the generalized valuation and the constant growth equations are combined to arrive at the nonconstant growth valuation equation:Basically, this equation calculates the present value of dividends received during the nonconstant growth period and the present value of the stock's horizon value, which is the value at the horizon date of all dividends expected thereafter.Quantitative Problem 3: Assume today is December 31, 2013.
