What is the role of DNA in determining an organisms trait?

Answers

Answer 1

Answer: Everything. DNA contains genes and which genes a person has determines which (if any) proteins are formed. Based on how much of a protein is formed determines how strong a trait is expressed

How the metabolism of hetero trophy differs from that of autotrophs

Answers

In many functions of a living organism, it cannot make its own energy. It uses energy from its environment, retrieves and converts into a usable and edible matter. Organisms that can do this process is the autotrophs, they can facilitate photosynthesis which they gather energy from the sun, water and carbon dioxide in order to create energy by then, the transfer of this energy to other organism is played by the food chain –food web.

The options in the question contain both autotrophs and heterotrophs.
(a) A giant redwood tree = Autotroph
(b) A spider = Heterotroph
(c) A rose bush = Autotroph
(d) A mushroom = Heterotroph
(e) A blue whale = Heterotroph
Autrophs are the organisms that have the capacity to form their own food from inorganic substances like the carbon dioxide.
Heterotrophs are the organisms that cannot produce their own food but depends on other animals or plants for their nutritional needs.

True or false the more variables you can test in an experiment the better the results

Answers

never ever!!!!! if you have multiple independents you will never know which one(s) changed your dependent...dude who already answered.... don't just guess!!!!!

True, because then you have a broader view of the results. In other words, the majority of more variables is better than less variables.

Organisms with advantageous adaptations are more likely to survive and reproduce than organisms without the advantageous adaptations. This phenomena is known as natural selection.In order for natural selection to occur
A.) organisms within a population must have some genetic variation.
B.) there must be more male organisms than female organisms.
C.) all of the organisms within a population must be exactly the same.
D.) one population must become extinct so another can be created.

Answers

Inorder for natural selection to occur organisms within a population must havesome genetic variation. Naturalselection is when species learn to adapt to their environment. They could (1)differential reproduction, that is, not all organisms are able to reproduce totheir fullest capacity because nature cannot simply sustain it and (2) acquire genes,that is heredity. Certain characteristics of organisms tend to survive if itcontinues to strive. If it survives, this trait is passed down to the nextgenerations forgetting the other traits but only the one who could survive theenvironment. Therefore it is true that natural selection is when‘organisms inherit advantageous traits, and tend to reproduce more successfullythan other organisms’.

A. organisms within a population must have some genetic variation.

Scientists include controls in their experiments why is a control important

Answers

Answer:

"The control experiments are basically done to compare the main experiment and the experiment done in controlled manner so as to observe the changes and also to minimize the changing effect"

Explanation:

The scientists include the control in their experiments which can help them to minimize the changes and can observe the changes meticulously. In control experiment the observation are made with minimum effect of the variables leaving the independent variable. This type of experiments help in increasing the reliability of the output. The control experiments are basically done to compare the main experiment and the experiment done in controlled manner so as to observe the changes.

Which type of precipitation forms when water droplets fall through a cold layer of air and freeze on their way to the ground?A) Hail
B) Rain
C) Sleet
D) Snow

Answers

Answer:

I think the answer is C sleet.

Explanation:

Rain melts on its way down, so it can't be that. Hail and snow refreeze, so the answer is sleet.

I hope this helps :)

sleet is ur answer! the guy above me was right as well
