Answer:

Option C, 13 births per 1000 people

Explanation:

The number of children born in 2015 in USA is 3,978,497 which is approximately 4 million in number.

Considering the population of USA in 2015  which was 32.1 crore, the number of birth per 1000 person in the country is worked out to be 13 per 1000 people.

However, this mark has not yet increased after 2015. hence, it can be said that there are 13 babies taking birth in every 1000 people.

Hence, option C is correct.

Number the steps from when the stimulus received to when the body reacts​
Natasha2012 [34]

The given question is not complete. The complete question is:

Number the steps from when a stimulus is received to when the body reacts.

The stimulus is received by sensory receptors.

Motor neurons cause muscles to contract so the body can react to the stimulus.

The brain processes the information through interneurons.

Interneurons transfer response information to motor neurons.

Sensory neurons carry stimulus information to the brain or spinal cord.

Answer:

The body of an organism like humans reacts towards each of the external stimuli of the environment like the smell of the food and even to the internal stimulus like hunger or pain. Thus, it can be considered that one is stimulated all the time and reacts towards the constituents found in the surroundings. The entire procedure of the organism reacting towards the stimuli are as follows:  

1. The sensory receptors receive the stimulus.  

2. The stimulus information is further carried to the spinal cord or the brain by the sensory neurons.  

3. The processing of the information in the brain takes place with the assistance of interneurons.  

4. After that the response information is mediated towards the motor neurons by the interneurons.  

5. The motor neurons eventually result in the contraction of muscles showing that the body is reacting towards the stimulus.

The LMand LNalleles at the MN blood-group locus exhibit codominance. Give the expected genotypes and phenotypes and their ratios
Dmitry [639]

Answer:

Please find the expected genotypes and phenotypes of the progenies of each cross below.

Explanation:

In the MN blood-group locus of the gene, alleles LM and LN exhibit codominance i.e one allele is not dominant or recessive to the other, hence, they are both expressed when they occur in a heterozygous state (MN).

Considering the following crosses (find the punnet square attached);

a)LMLM x LMLN - The progeny are LMLM and LMLN in the genotypic ratio 1:1. Phenotypic ratio is Blood type M (1) : blood type MN (1)

b) LNLN x LNLN - The progeny are all LNLN offsprings with a phenotypic and genotypic ratio 4:0. All offsprings will have a blood type N (4)

c) LMLN x LMLN - The progenies are LMLM, LMLN and LNLN in the genotypic ratio 1:2:1 respectively. The phenotypic ratio is Blood type M (1) : L

Blood type MN (2) : Blood type N (1)

d) LMLN x LNLN - The progeny are LMLN and LNLN with genotypic ratio 1:1 and phenotypic ratio blood type MN (1) : blood type N (1)

e) LMLM x LNLN - The progeny are all LMLN offsprings with penotypic ratio blood type MN (4)

Which material would best be carried in solution by a stream?
SashulF [63]
The answer to this would be a quartz.
Quartz is a mineral composed of silicon and oxygen atoms in a continuous framework of SiO₄ silicon–oxygen tetrahedra, with each oxygen being shared between two tetrahedra, giving an overall chemical formula of SiO₂
so that is why quartz would be the best be carried in solution by a stream.

Hope this helped :)

Why food must be digested before entering your cells?
S_A_V [24]

Answer:

Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body.     Protein must be broken down into amino acids.     Starches break down into simple sugars.     Fats break down into into fatty acids and glycerol.
