Explanation: The significance to scientists of finding a new, unknown fossil is that it provides evidence of links between evolutionary species.

Answer 2

Organisms arose as a result of these changes, and some of their remains have been preserved as fossils. An organism's type, life history, and preservation method can all be ascertained by studying a fossil. Thus, option D is correct.

What are the features of finding a new, unknown fossil?

They can discover when and how various animals existed millions of years ago by studying fossils. Fossils can sometimes show scientists how the Earth has changed over time.

The discovery of a new, undiscovered fossil is significant to scientists because it shows connections between evolutionary species.

Fossils with remarkably similar geometries are thought to be from the same species. It is considered that fossils with somewhat differing geometries come from a separate species. Usually, the fossil species has been researched and given a name.

Therefore, It provides evidence of links between evolutionary species.

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...

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.

can produce them.
mRNA destroyer concentration has a greater influence because it is destroying mRNA before

mRNA destroyer concentration has a greater influence because mRNA is destroyed right
after the proteins are produced.

Answers

Answer:

mRNA destroyer concentration has a greater influence because it is destroying mRNA before  proteins can even be produced.

Explanation:

Proteins are synthesized from mRNA through the process of translation. mRNAs are first synthesized from a coding DNA template through the process of transcription. Hence, if mRNAs are destroyed, it means proteins will not be synthesized at all.

Protein not being synthesized at all means that mRNA destroyer concentration has a greater influence on protein levels than protein degradation. With protein degradation, not all the protein is degraded at once and some quantity of the protein can still be found, but with mRNA destroyer concentration, no protein can be found at all because it was not synthesized in the first place.

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.

How are the molecules in photosynthesis and cellular respiration similar? Please include descriptions of the molecules

Answers

Answer:

They are similar because they both produce energy but in two different forms.

Photosynthesis- It produces oxygen and G3P, simple carbohydrate molecules that are high in energy and can be converted into glucose, sucrose, or other sugar molecules.

cellular respiration-During cellular respiration, a glucose molecule is gradually broken down into carbon dioxide and water.

They exhibit the same responses, but they do so in reverse. Carbon dioxide and water are converted during photosynthesis into glucose and oxygen. Carbon dioxide and water are produced during respiration in exchange for glucose and oxygen.

What similarity in photosynthesis and cellular respiration?

Energy transformations from one form to another are a part of both respiration and photosynthesis through a sequence of metabolic reactions.

The reactions that are carried out by both processes—which both use and produce ATP—are carried out on membranes and are managed by enzymes.

Light energy is converted by photosynthesis into chemical energy that is stored in glucose, which is then released by cellular respiration to create ATP, the life-sustaining compound.

Therefore, They are similar because they both produce energy, but in two different forms.

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.

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.

Shivering and vasoconstriction would be signaled to cause a: A. increase in pH. B. decrease in temperature. C. decrease in pH. D. increase in temperature.

Answers

Answer:D

Explanation: shivering occurs when someone is cold and vasoconstriction is when the blood vessels close to the skin and the veins closer to the skin surface constrict as a result of dat air doesn’t enter the body

Vasoconstriction is the narrowing of the blood vessels that hinders blood flow. Vasoconstriction and shivering will lead to an increase in the temperature through thermoregulation. Thus, option d is correct.

What is thermoregulation?

Thermoregulation is the maintenance and balancing of the temperature and heat in the body. They are regulated by many factors including shivering and vasoconstriction.

During the vasoconstriction, the blood vessels close to the skin surface close and the body shivers as a result of cold or decreased temperature. This signals the body to increase the temperature so that shivering can be stopped.

Therefore, vasoconstriction and shivering signal the body to increase the temperature.
