Which diagram below shows the process of meiosis - Diagram A or Diagram B? How do you know? Explain all the details that prove you are correct.

Answers

Answer 1

B. Meiosis is division of a cell from diploid number of chromosomes to haploid number of chromosomes. This type of division is used for gametogenesis-or making of sex cells. If we look at the starting number of chromosomes, we see 4, then at the end of the diagram we see four cells each with 2 chromosomes.

Answer 2

From the diagram, meiosis is shown by the diagram in B in the question.

What is meiosis?

Meiosis occurs when a cell divides in such a way that each daughter cell gets only half of the number of chromosomes in the parent cell.

Looking at the cell division in diagram B, we can see that there are only two chromosomes in each daughter nuclei out of the four chromosomes in the parent nuclei hence that us meiosis.

What is biochemical reaction?

Biochemical reactions are chemical processes that occur in live cells to support life and promote cell growth.

To expedite most biochemical reactions, an enzyme is a type of biological catalyst.

The amount of activation energy required for the reaction to start is decreased by enzymes. Most enzymes are proteins that only interact with one particular chemical, known as their substrate.

The ratio of atoms in the reactants and products must always be balanced.

after death, the cornea absorbs fluid and becomes opaque. in a living person, the cornea is translucent due to _______________.

Answers

Given what we know about human anatomy, we can confirm that the cornea of a live human is translucent due to the arrangement of its collagen fibers and the lack of vascularity.

One important factor in the translucent nature of the cornea and lens is its lack of vascularity. This area of the eye has few if any vascular components, which contributes to its lack of pigment.

However, the main component that contributes to the translucent nature of the human cornea is its very specific arrangement of collagen fibers.

The bundled nature of these fibers, together with the water content of the cornea, allow it to remain translucent.

Why do the alveoli fill with fluid.

Answers

Answer:

Your lungs contain many small, elastic air sacs called alveoli. With each breath, these air sacs take in oxygen and release carbon dioxide. Normally, this exchange of gases occurs without problems. But sometimes, the alveoli fill with fluid instead of air, preventing oxygen from being absorbed into your bloodstream.

Explanation:

Answer:

The fluid represents the outermost layer of the alveolar surface that is directly exposed to air and thus to the environment. Alveolar fluid prevents desiccation of the epithelial cells and also functions as a physical protection barrier against inhaled particles and irritants. Explanation: hope this helps

A) T2 protein and T4 DNA

B) T2 protein and T2 DNA

C) a mixture of DNA and proteins of both phages.

E) T4 protein and T2 DNA

A bacterium infected with an experimentally constructed bacteriophage will give new phages with the virus' DNA and the type of proteins that this DNA encodes.

A bacteriophage is a virus that attaches itself to a bacteria and uses it to replicate itself. Viruses have two main parts, a protein coat and their DNA inside it.

The experimentally constructed bacteriophage has one type of protein that makes the coat, the T2. This type of protein will allow the virus to attach and infect the bacteria. Once the virus attaches itself to the bacteria, it will introduce its DNA, T4 type, and use the bacteria elements to replicate it and create new phages.As a result, the new phages will have T4 DNA, and the proteins that the virus synthesizes will be the same type as the DNA.

In conclusion, The new phages produced would have D) T4 protein and T4 DNA.

How many minutes are there in a 40-hour week?

A:2,000

B:2,400

C:1,400

D:1,200

Answers

The answer is B
Explanation:
You multiply 40 by 60 to get 2,400

There will be 2,400 minutes in a week of 40 hours. This can be calculated by the help of unit conversion of time. Thus, the correct option is B.

What is Unit conversion?

Unit conversion is the change of one form of unit to another form of unit of different system such as conversion of units of measurement of weight from gram to kilogram or milligram.

Unit conversion of one unit to another unit is used in order to have accuracy and avoiding the confusion in measurements. For example, the length of pencil is not measured in kilometers rather it is measured in centimeters or inches, which are comparatively smaller than kilometers. In such a case, one has to convert the unit of length from kilometer (km) to centimeter (cm).

The week of 40 hours can be converted into minutes by:

Number of minutes in 1 hour = 60

Therefore, the number of minutes in 40 hours = 60 × 40 = 2,400 minutes

Therefore, the correct option is B.

MPG A n n u a l T o n so fG H G At Sunny Middle School, Ms. Addisons class is investigating how greenhouse gases (GHGs) contribute to global climate change. They wrote their research on note cards: Greenhouse gases cause climate change by trapping heat on the planet. Greenhouse gases contribute to smog and air pollution, which can cause respiratory diseases, like asthma. Extreme weather, disruptions to the food supply, and increased wildfires are also caused by greenhouse gases. Where do greenhouse gases come from? Mia asked. One of the most common greenhouse gases is carbon dioxide, also known as CO2. People release CO2 into the atmosphere when we burn fossil fuels (like coal and natural gas) for energy and transportation, Ms. Addison answered. The class examined the graph to the right. The source for the largest percentage of CO2 emissions for a typical household was vehicles. The students conducted some research and found: > Highway vehicles release about 1.7 billion tons of GHGs each year. > Each gallon of gasoline burned creates 20 pounds of GHG. > A typical vehicle releases 6 to 9 tons of GHG into the atmosphere each year. For their group project, Mia and Ichiro researched hybrid cars that combine gas and an electric motor. Awesome, so it consumes less fuel and emits less CO2 into the environment, Ichiro said. While hybrid cars are better for the environment, Im seeing that some people are hesitant to buy one because of the higher purchase price, Mia noted. They found the graph to the right, which shows the miles per gallon (MPG) and the annual tons of GHG produced by 8 different types of cars. If each gallon of gasoline burned created 20 pounds of GHG, and the price of gasoline was $2.454 per gallon, how much money was saved annually on gas by the car that got 40 miles per gallon when compared to the car that got 20 miles per gallon?
