Pleaseeeeeeeeee help​ and actualy answer

Answer:

Preschoolers, ages three to six, should be at the "preoperational" stage of Piaget's cognitive development theory, meaning they are using their imagery and memory skills. They should be conditioned to learning and memorizing, and their view of the world is normally very self-centered.

Explanation:

so early adulthood think so

The stage of human development that might be most concerned with cognitive function is advanced adulthood. The correct option is D.

Cognitive functions are the psychological functions that are the mental processes that are done to express feelings and actions. They are eight types of cognitive functions.

In advanced adulthood, humans use most of the cognitive functions of the body.

Thus, the correct option is D, advanced adulthood in regard to the stage of human development.

Answer:

X: anaphase

Y: independent assortment

Explanation:

Homologous chromosomes seperate during meosis 1 while chromosomes seperate at meosis 2.  

Chromosomes are structures present in the nucleus of plant and animal cells. It transfers the genetic information from parent to offspring. Humans have 23 pairs of chromosomes. In which 22 pairs are autosomes while the 23rd pair is the sex chromosome.

The correct answer is:

Option A. OX: anaphase and Y: independent assortment

The explanation for this is:

Therefore, in anaphase, the homologous chromosomes separate, which increases genetic diversity because of independent assortment.

Answer:

A null hypothesis would be that caffeine doesn't stimulates sunflower plants to grow taller.

Explanation:

Null hypothesis: In research methods, the term "null hypothesis" is described as a type of hypothesis that proposes that there's no difference between specific characteristics of a particular data gathering process or population.

Function: The main aim of "null hypothesis" is to prove whether or not a specific test or study is supported and is separated from the researcher's own decisions and values. It is responsible for providing a way to a given study or test and is represented by H0.

Answer:

so the answer is peer review

Explanation:

Yes, other scientists are participating in this activity not in a direct way but in an indirect way. The scientists are participating in peer review.

The scientific paper was written by scientists which provide the data and conclusion of entire experiments. To write scientific experiments we need to collect data, frame hypotheses, research methodology, and find out the conclusion are some of the steps to writing a scientific paper.

Testing hypotheses often involves designing experiments. In the given experiment Dr. Sanchez found that star is consumed by a nearby blackhole. But other scientist found the unusual star as well.

This suggests that both scientist thought on different aspect. This suggest peer review.

Therefore, Yes, other scientists are participating in this activity not in a direct way but in an indirect way.

Answer:

The correct answer is - Hox gene.

Explanation:

Synpolydactyly is a joint presentation of syndactyly is the condition of the partially or completely duplicated fingers or toes and weblike development in between toes and fingers.

This takes place due to the Gene of HOX family that has mutated to rise this condition in the individual. The gene that is responsible for this genetic condition is the mutation in the D13 gene.

Explanation:

Answer:

If a blue-eyed offspring forms from black-eyed parents, the blue-eyed trait must be recessive.

Explanation:

The blue-eyed trait is the recessive one because otherwise it could not come from parents with black eyes. A recessive trait is only expressed when both alleles for that trait are the same, and can only come from parents with the same trait, or heterozygotes.

In this case, both parents must be heterozygous, i.e. carriers of the recessive allele. If black eyes is B and blue eyes is b, then the genotype of the parents would be:

In a Punnett square can be seen the crossing:

Bb X Bb

Alleles    B     b

B           BB    Bb

b           Bb    bb

Where the offspring could be:

Therefore, if blue eyes is the recessive trait, as if it were the dominant trait it could not be the product of black-eyed parents.

The study of a living being is called biology.

The correct answer is recessive genes or mutation.

The character in the living organism is due to the gene present in the body. The genes are present in a pair. The single gene is known as an allele. The two alleles are as follows:-

In this question, the parents have a black color eye but the offspring has blue color eyes. This is due to recessive gene inheritance because this gene is dormant in their parent and shows its character in this generation.

The chances of this case are 1/4 out of total.

The mutation is also the reason for the blue eyes because the abnormal change beside the population is called a mutation.

Hence, the correct answer is Recessive and mutation.

Answer:

The organism's genotype encodes their phenotype because the genotype corresponds to the characteristic that is determined by genes —formed by fragments of DNA— which are transcribed into mRNA to be translated into amino acid sequences in the synthesis of proteins, determining the morphological and functional characteristics of an organism, that is, its phenotype.

Explanation:

Genotype corresponds to the genetic information contained in the DNA, according to the sequence of nucleotides in its molecular structure. This genotype includes characteristics or polymorphisms that define the appearance and function of living beings.

Each DNA molecule constitutes a chromosome, formed by genes —DNA fragments— each of which determines specific characteristics.

When DNA is transcribed into mRNA, information is being sent that is necessary for the incorporation of amino acids into a protein that is being synthesized. The proteins, in turn, determine morphological and functional characteristics that constitute the phenotype of an individual.

Answer:

Two of the bases are purines- adenine and guanine. The pyrimidines are thymine and cytosine.

Answer:DNA is normally found as a loosely contained structure called chromatin within the nucleus, where it is wound up and associated with a variety of histone proteins. When a cell is about to divide, the chromatin coils tightly and condenses to form chromosomes

Explanation:

Answer:

The intense and constant activity of insulin synthesis explains why pancreatic beta cells possess more rough endoplasmic reticulum and ribosomes than other cells.

Explanation:

Both ribosomes and the rough endoplasmic reticulum are necessary for protein synthesis to occur. In cells whose function is to produce substances, such as glands, the content of these cellular structures is higher in order to fulfill their function.

The pancreatic beta cells, located in the islets of Langerhans, have the function of synthesizing insulin, an endocrine hormone in charge of regulating the glucose content in the blood. Because the beta cells constantly produce insulin, their content of rugged endoplasmic reticulum and ribosomes is high, in order to satisfy the demand for this hormone in the body.

Answer:

D.VACUOLE

Explanation:

Given:

Fixed charges = $40

Variable charges = $1.70 for each mile.

To find:

The equation that represents the total cost y for x miles towed.

Find the y-intercept and interpret  its meaning in the context of the situation. ​

Solution:

Let y be the total cost for x miles.

Fixed charges = $40

Variable charges for 1 mile = $1.70

Variable charges for x mile = $1.70x

Now,

Total changes = Fixed charges + Variable changes

[tex]y=40+1.70x[/tex]

Therefore, the required equation is [tex]y=40+1.70x[/tex].

Putting x=0 in the above equation, we get

[tex]y=40+1.70(0)[/tex]

[tex]y=40+0[/tex]

[tex]y=40[/tex]

Therefore, the y-intercept is 40. It means the charges to hook a car is $40 if it is towed 0 miles.

Answer:A

Explanation:

Organisms are classify on the basis of kingdoms Bacteria, Protista, Fungi, Plantae, Animalia, Phylum. Therefore, option (A) is correct.

Organisms can be classified according to any number of criteria, including overall similarities, colors, ecological functions, etc. However, it is generally agreed that the most useful way for scientists to organize biological diversity is to group organisms according to shared evolutionary history.

It is divided into phyla or divisions, which are further subdivided into classes. Further divisions include order, family, genus and species, in that order. Thus, species is the basic unit of classification.

Organisms are usually grouped together based on their unique characteristics. The classification of an organism often provides useful information about its evolutionary history and which other organisms are related to it.
