Answers

Answer 1

Answer:

The question lacks options, the options are:

A. understand the viewpoint of other people.

B. realize that the term heavy describes an object one way and the term big describes it another way

C. understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.

The answer is C

Explanation:

Piaget proposed the theory of cognitive development, which talks about how human intelligence is developed. Piaget worked with Children because he believed they played a significant role in the development of cognitive intelligence. Based on his work, he proposed four stages of cognitive development viz: sensorimotor, preoperational, concrete operational and formal operational stages.

However, in the preoperational stage, Piaget described children between ages 2-7 as being in this stage of cognitive development where they are yet to comprehend mental logic. One characteristics of this stage is CONSERVATION, which is the ability to know that changing a substance's appearance doesn't change the properties of that substance. Piaget proposed that Children between the ages of 2-7 lacked this conservative characteristics.

He performed an experiment where he used two beakers with the same amount of liquid. He then emptied the contents of one of the previous beakers into a new beaker with different shape (longer). Piaget was able to notice that Children at the pre-operational stage were unable to understand that the contents of the two beakers (longer one and previous beaker) were still the same despite the beaker has been changed.

Hence, according to Piaget, a child has acquired the cognitive skill of conservation when he/she is able to understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.

Consider the following chromosomes and if they are affected by hemophilia. X - unaffected X chromosome, x = X affected by hemophilia, and Y = Y chromosome. If an Xx female and XY male have children, what fraction of their offspring will have an affected chromosome, and what fraction is likely to be affected by the hemophilia? (1 point) A. 1/4 and 1/2 B. 1/2 and 1/4 C. 1/2 and 1/3 D. 1/4 and 1/4 Ive been stuck on this for a while now, can someone please assist?

Answers

Answer:

B. 1/2 and 1/4

Explanation:

Hemophilia is a disease inherited in humans. It is only carried on the X chromosome, hence, it is said to be X-linked. In this question;

X - unaffected X chromosome

x = X chromosome affected by hemophilia,

Y = Y chromosome

Hence, in a cross between a Xx female (carrier) and a XY male (unaffected), the following chromosomes will be present in the gametes produced by each parent:

Xx- X and x gametes

XY- X and Y gametes

Using these gametes in a punnet square (see attached image), offsprings with genotypes: XX, Xx, XY and xY are produced.

XX (1) - unaffected normal female

Xx (1) - unaffected carrier female

XY (1) - unaffected normal male

xY (1) - affected male

Based on the questions;

- 2 out of the possible 4 children have the affected chromosomes i.e. both xY son and Xx daughter have the x chromosome. Hence, the fraction is 1/2

- 1 out of the 4 possible children is affected by hemophilia, which is the xY son. Hence, the fraction is 1/4.

Tara placed a grape in a solution, after sometime she noticed that the grape started to shrink.
a. Name the solution and explain.
b. Then Tara placed the raisin in a solution and noticed it started to swell up. Name the solution and explain

Answers

Answer:

a. Hypertonic solution

b. Hypotonic solution

Explanation:

There are basically 3 types of solutions in biology,

1) Isotonic-Same concentration of solute and solvent inside  the grape and in the solution.

2)Hypotonic solution-More concentration of solvent in the solution than in the grape.

3)Hypertonic solution-More concentration of solvent in the grape than in the solution.

Now,

a. Tara had kept the grape in a hypertonic solution. The solvent will start draining from the grape to equalize the concentrations of solvent inside and outside. So, the grape shrank due to loss of water.

b. Tara kept it in a hypotonic solution. The solvent will start entering the grape to equalize the concentrations of solvent. So, the grape started swelling.

what are sex hormones?why are they named so? state their function.

Answers

Answer:

Sex hormones or hormones of the reproductive organs are certain cells in the reproductive organs that produce hormones.

The testis produces testosterone,the male sex hormone,and the ovaries produces oestrogen and progesterone, the female sex hormones.

In a sexually mature male,testosterone influences sexual behaviour, and together with FSH,regulates sperm production in the seminiferous tubules of the testes.

Sexually matured females undergo a regular 4-week reproductive or menstrual cycle during which a mature egg is released.This cycle is regulated by oestrogen and progesterone. During pregnancy, progesterone inhibits egg production (ovulation),brings about the development of the placenta and prevents the uterus from contracting....I hope this answers your question...

Answers

Oceans, lakes, seas, and clouds are examples.

The hydrosphere is made up of all the water on the planet, including the water found below the surface and in the atmosphere. A planet's hydrosphere may be liquid, vaporous, or composed of ice. The three surface water bodies on Earth are oceans, lakes, and rivers.

What are some non examples of hydrosphere?

It comprises all surface waters that are liquid or frozen, groundwater that is contained in soil or rock, and atmospheric water vapor. The hydrologic cycle continuously circulates almost all of these waters. In wells and aquifers, it can also be found underground as groundwater.

Within the hydrosphere, water circulates in a cycle. Clouds contain water that eventually falls to Earth as rain or snow.

Therefore, Rivers, lakes, and seas are where this water gathers. The cycle is then restarted by its evaporation into the atmosphere. The water cycle refers to this.

here are times where you will be provided with BUD dates. When you do not have access to the BUD dates, you will have to determine that date yourself. What is the appropriate BUD date for a water containing oral formulation? Not later than 14 days Not later than 30 days

Answers

Answer:

Explanation: Not later than 14 days.

Beyond Use Date (BUD) is the date after which a compounded sterile preparation may not be stored or transported. This time is calculated from the date of compounding, and it is different from expiration date. This is because the BUDs are assigned with a different approach from those applied to assigning expiration dates to  manufactured drug products. Also, compounded preparations are intended for administration following short-term storage. So, the BUD is the date after which a compounded preparation shall not be  used. A reliable BUD is established to ensure that the preparation  has an accepted quality and purity at least  until the labeled BUD.

BUD is calculated by:

Type of container in which it is packagedHow long the medication will be takenType of drugHow fast is the drug degradatedStorage conditionsDosage of the medicationNature of the drug and its degradation mechanism Potential for microbial proliferation in the preparation

For Nonaqueous Formulation, the BUD is not later than 6 months or the time  remaining until the earliest expiration date of any API (Active pharmaceutical ingredient), whichever is earlier.  

For Water-Containing Oral Formulation, the BUD is not later than 14  days when it is stored at controlled cold temperatures.

For Dermal and Mucosal Liquid, Semisolid Formulations/Water-Containing Topical, the BUD is not later than 30 days.
