9. A person instinctively curls over his abdominal area in times of danger. Why?

Answer:

Enzyme- Peptidase/protease

Explanation:

According to this question, a student is conducting an experiment to determine the roles of molecules in metabolic processes such as digestion. Based on what she found out that the molecule, which itself can be broken down into amino acids, can also break down proteins into amino acids, this suggests that the molecule being described is a PROTEOLYTIC ENZYME.

This is because an enzyme is made up of proteins which can be denatured or broken down into its simplest unit (amino acids) and also, a substance that breaks down amino acid is said to be PROTEOLYTIC.

However, another observation that the molecule is found in high concentrations in the small intestine was made, hence, the enzyme is a PEPTIDASE OR PROTEASE, which are secreted into the small intestine by the pancreas to aid digestion of proteins.

Let's denote the width of the park as "w" miles. According to the given information, the length of the park is 1/2 miles and the area of the park is 6/8 square miles.

The area of a rectangle is given by the formula: Area = Length × Width

Given that the length of the park is 1/2 miles and the area of the park is 6/8 square miles, we can set up the following equation:

1/2 * w = 6/8

To solve for "w", we can multiply both sides of the equation by 2 (to eliminate the fraction):

2 * (1/2 * w) = 2 * (6/8)

w = 12/8

Now, we can simplify the fraction w = 12/8:

w = (12 ÷ 4) / (8 ÷ 4)

w = 3/2

So, the width of the park is 3/2 miles.

The African animals given in the chart are lions, cheetahs, and zebras. The chart presents their population sizes in 1990 and 2000. The population of zebras is higher than the lion and cheetah populations. The lions' population declined from 100,000 to 47,000 between 1990 and 2000 is Lion and cheetah populations compete for the food source of zebras, and cheetahs outcompete lions.

Likewise, the population of cheetahs decreased from 7,500 to 2,500 between 1990 and 2000. However, the population of zebras remained relatively stable at 50,000. Therefore, one could deduce that lions and cheetahs are competing for the same food source, which is zebras.

Lions and cheetahs have a diet that includes zebras. As a result, zebras serve as a food source for both lions and cheetahs. This indicates that there is competition between lion and cheetah populations. It is important to remember that the population of zebras remained stable during this period, indicating that the food source remained plentiful. As a result, the reason for the decline in lion and cheetah populations must be due to other factors.

Therefore, the statement that is best supported by the numbers in the chart is that lion and cheetah populations compete for the food source of zebras, and lions outcompete cheetahs. The decline in lion and cheetah populations could be attributed to numerous causes, including habitat loss, disease, and human interference, among other factors.

Starch is a carbohydrate, but specifically a polysaccharide. Unlike fats they cant be broken down so #2 is not correct for that reason. Since polysaccharides are a polymer of complex sugars they can be broken down to simple sugars in order for it to enter cells because the cell needs to transport the molecules in small portions not big.

Answer: The scientific method is a series of processes that people can use to gather knowledge about the world around them, improve that knowledge, and attempt to explain why and/or how things occur. This method involves making observations, forming questions, making hypotheses, doing an experiment, analyzing the data, and forming a conclusion.

Explanation:

After a researcher establishes an empirical research question, the next step is to complete a literature search. Thus, the correct option is B.

Research may be defined as the process of methodical investigation into and study of materials and sources in order to derive facts and reveal new conclusions on the basis of evidence.

The first step of scientific research is to establish an empirical research question that is valid, accurate, and can be testable.

After this, one must require to complete a literature search in order to derive new concepts, understandings, and knowledge on the basis of previous identical experiments.

Therefore, the completion of a literature search is the next step which is followed by the establishment of an empirical research question.

A hypothesis is a speculative claim or explanation put forth based on scant data and used as a springboard for additional research or trial. It is an educated guess or testable prediction regarding the correlation between two variables or phenomena.

By manipulating the concentration of fertilizer as the independent variable and measuring the resulting plant growth as the dependent variable, we can test the hypothesis and determine if there is a correlation between fertilizer concentration and plant growth.

100% of the offspring will be homozygous round in this cross.

What is a homozygous?

A homozygous round is an organism that has two identical copies (alleles) of a particular gene that codes for the trait "round." This means the organism will always express the round trait, regardless of the environment or the presence of other alleles.

This is because the round pea plant that is heterozygous still carries two copies of the round gene. When it is crossed with a homozygous round pea plant, all of the offspring will have two copies of the round gene, making them homozygous round.

Answer: Female is 12.1-15.1 g/dL or 121-151 g/L

Male is 13.8-17.2 g/dL or 138-172 g/L

Explanation:

Answer:

First thing is that word “autonomous” given in the question is actually “ autosomal”.

Now let's start solution:

Frequency of dominant allele “A” is denoted by p.

Here p = 0.6

Frequency of recessive allele “a” is denoted by q.

According to Hardy - Weinberg equilibrium

p + q = 1

Hence q = 1 - p = 1 - 0.6 = 0.4

Now in question what is asked is about frequency of recessive phenotype (aa).

According to Hardy - Wienberg equilibrium frequency of recessive phenotype is q2 (q square).

Frequency of recessive phenotype is = q2 = 0.4 x 0.4 = 0.16

Now Number of recessive phenotype in a population of 10000 is

= frequency of recessive phenotype x total population

= q2 x 10000

= 0.16 x 10000

= 1600

a system for the detection of objects under water and for measuring the water's depth by emitting sound pulses and detecting or measuring their return after being reflected.

"a weak sonar signal"

Answer:

0.3106 seconds

Explanation:

Frequency= 20,000-Hz

The speed of echoes sounds can be calculated using the expression below;

Y= ( 2x/t) ...........................eqn(1)

t= overall time taken

x = maximum depth = 230m

Y= speed of echoes sounds

Speed of sound in water= 1,481 m/s which is a constant with little variation.

If we substitute the given values into eqn(1) we have

1481 = (2× 230)/ t

1481 × t= 460

t=460/1481

t=0.3106 seconds

Hence, the minimum time between pulses (in fresh water) is 0.3106 seconds
