What does the data reveal about the relationship(s) between the impactor's mass and crater depth?

Answers

Answer:

For each ball, the crater diameter increased as the height of the ball drop increased. My conclusion is that crater diameter increases with increasing mass. Also as the height of the ball increases, so does the crater diameter. Thus crater diameter is proportional to the mass and velocity of the impactor.

From fossil evidence, you know two species shared a common ancestor approximately 50 million years ago. In comparing a known neutral sequence between rats and mouse, you found 92 base differences in 1000bp. From this information, which of the following values is closest to what you would predict the mutation rate to be?
a. 1 x 10-9
b. 4 x 10-9
c. 2 x 10-9
d. 5 x 10-9
e. 5 x 10-8
f. 8 x 10-9

Answers

Answer:

Option c ([tex]2\times 10^{-9}[/tex]) is the correct alternative.

Explanation:

Given:

Common ancestor,

= 50 million years ago

Base differences,

= 92

Now,

The predicted mutation rate will be:

= [tex]\frac{92}{50\times 10^6\times 1000}[/tex]

= [tex]\frac{1.84}{10^9}[/tex]

= [tex]1.84\times 10^{-9}[/tex]

or,

= [tex]2\times 10^{-9}[/tex]

Thus the above solution is the right one.

From his observations in the oceanic islands like the Galapagos, Darwin felt that: isolation is a significant factor in adaptation and speciation spontaneous generation is a significant factor in adaptation and speciation volcanic soils are a significatnt factor in adaptation and speciation inheritance of acquired characteristics is a significant factor in adaptation and speciation. none of these is correct

Answers

Answer:

isolation is a significant factor in adaptation and speciation

Explanation:

In the theory of evolution by natural selection proposed by Darwin, adaptation refers to the adjustment of organisms to their environments in order to increase their chances of survival in that environment. In the Galapagos Islands, Darwin observed that finches had different types of beaks adapted to the type of food they ate. From this observation, Darwin proposed that finches evolved to eat different food sources. In this case, the islands lead to an adjustment (evolutionary) process by which geographically isolated individuals accumulate genetic differences in order to adapt them to the environmental conditions in the islands, which then may also prevent breeding between individuals from different islands when they are reunited (i.e., it may also lead to speciation).

Transcriptional termination by RNA polymerase is favored when tryptophan levels are low (1) / high (2), because the low levels (3) / abundance (4) of charged Trp-tRNATrp causes the ribosome to quickly synthesize the leader polypeptide (5) / stall at the pair of Trp codons (6). This termination (7) / elongation (8) structure forms because the 3-4 stem loop (9) / the ribosome (10) allows region 2 to pair with region 3.
a. 1,3,6,8,9.
b. 2,3,5,8,9.
c. 1,4,6,7,10.
d. 2.4,5,8,10.
e. 2.4.5.7.9.

Answers

Answer:

The answer is "Choice e".

Explanation:

The additional Trp Operon function is gene expression attenuation. If tryptophan levels are high, RNA Polymerase endings of glutamate operone are favoured, since the excess of Trp-tRNATrp load causes rna to rapidly synthesise the lead polyprotein and region iii base pairs with cluster 4 and creates stepping chain structures which signal mrna cessation. Rest both options are wrong in regards to the glutamate operon amplification transmission termination mechanism.

Explain the advantages to a plant of having its cell membranes surrounded by cell walls

Answers

Answer:

Advantage of cell walls

It protect and support the cell .

To give difinite shape for the cell.

Having cell walls surrounding cell membranes provides several advantages to plants, including structural support, protection against pathogens, regulation of water balance, and prevention of cell rupture.

The cell wall is a rigid structure located outside the cell membrane in plant cells. It is composed primarily of cellulose, a complex carbohydrate. Here are the advantages of having cell walls:

Structural Support: Cell walls provide mechanical support to plant cells and help maintain the overall shape and structure of the plant. They allow plants to stand upright and withstand environmental forces such as wind or gravity. The cell walls of adjacent plant cells are interconnected, forming a strong network that provides stability to the plant as a whole.

Pathogen Protection: The cell wall acts as a physical barrier against pathogens such as bacteria and fungi. It prevents the entry of pathogens into the plant cells, reducing the risk of infection. Additionally, the cell wall can contain antimicrobial compounds and other defense molecules that provide further protection against pathogens.

Water Regulation: The cell wall plays a crucial role in regulating water balance within plant cells. It helps maintain turgor pressure, which is essential for cell expansion and overall plant growth. The cell wall allows water to enter and exit the cell in a controlled manner, preventing excessive water uptake or loss.

Cell Rupture Prevention: The rigid cell wall helps prevent cell rupture or bursting when the internal pressure within the cell increases. It provides strength and stability to the cell, allowing it to withstand internal pressure changes without bursting.

Overall, the presence of cell walls in plant cells offers significant advantages in terms of structural support, protection against pathogens, regulation of water balance, and prevention of cell rupture. These advantages contribute to the overall health, growth, and survival of plants in diverse environmental conditions.

Explanation:

1.fallopian tube

2.an unborn or unhatched offspring in the process of development, in particular a human offspring during the period from approximately the second to the eighth week after fertilization (after which it is usually termed a fetus)

3.First, the zygote becomes a solid ball of cells. Then it becomes a hollow ball of cells called a blastocyst. Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes.

4.Eggs live in ovaries, and the hormones that control your menstrual cycle cause a few eggs to mature every month. When your egg is mature, it means it's ready to be fertilized by a sperm cell. These hormones also make the lining of your uterus thick and spongy, which gets your body ready for pregnancy.

5.The fertilized egg attaches to the lining of the uterus. The placenta then develops. The placenta transfers nutrition and oxygen to the fetus from mother. If the egg does not become fertilized, the lining of the uterus (endometrium) is shed during menstruation.

6.The egg cell travels down the fallopian tube into the uterus. The moment the egg cell leaves the ovary is called ovulation. Once a girl has had her first monthly period, ovulation usually occurs once a month

7.The average menstrual cycle is 28 days long. Cycles can range anywhere from 21 to 35 days in adults and from 21 to 45 days in young teens. The rise and fall of levels of hormones during the month control the menstrual cycle.

Select one:


Shivering by the muscles when temperature drops.


The attraction of platelets when a wound occurs.


Sweating due to an increase in body temperature.


The reduction of hormone production during pregnancy.

Answers

Answer:

2

Explanation:

The attraction of platelets when a wound occurs indicates a positive feedback. The correct option is B.

What is feedback mechanism?

The feedback mechanism is the body's mechanism for keeping hormone levels within desired limits.

The feedback mechanism is activated by an increase or decrease in hormone levels. The body has two types of feedback mechanisms: positive feedback mechanisms and negative feedback mechanisms.

Positive feedback loops and negative feedback loops are the two types of feedback loops.

Positive feedback increases system output, causing growth or decline. Negative feedback dampens output and helps to keep the system stable around an equilibrium point.

Platelet plug formation is thought to be a positive feedback process because ADP and VWF levels rise as more platelets activate to form the plug.

Thus, the correct option is B.
