a. biological
b. cognitive
c. biopsychosocial
d. psychodynamic

Answers

The biopsychosocial approach is most directly concerned with assessing the relative contributions of heredity and experience to personality development (Option C)

The Biopsychosocial Approach is an interdisciplinary model which was first developed by George Engel and Jon Romano (1977).

The biopsychosocial approach is a type of model that recognizes biological (inheritance), psychological, and social (environmental) factors as well as the interactions among these factors to understand the health and illness state of an individual.

Social factors include economical, environmental, and cultural factors (e.g. work concerns and family issues).

Biological factors include both genetic and biochemical factors.

According to this approach, both mind and body determine the health of the subject.

The hypothesis will state as follows: IF the concentration of acid increases, THEN, the amount of limestone dissolved will also increase.

WHAT IS A HYPOTHESIS?

A hypothesis is a crucial part of the scientific method. It is a testable explanation of an observation or a proposed answer to a scientific question.

A hypothesis, which must be testable via experimentation, can either be accepted or rejected depending on the outcome of the experiment.

A hypothesis is an IF, THEN statement that must include the independent and dependent variables of the experiment i.e. it must show how the dependent variable (effect) is affected by the independent variable (cause).

Yes, but maybe limit your experiment to a certain type of plant. Because you’re changing the type of plant and the frequency it may interfere. So maybe put only one specific type of plant- so maybe say something like “I want to observe whether my wild flowers grow faster depending on the frequency I water them- once a day in comparison to once every two days, or a week.”

A female has a brother who is color blind and a mother who is not.
What is the probability that the female is a carrier for the trait?

25%

100%

50%

0%

Answers

I’m pretty sure it’s a 50% chance since the colorblind mother has two kids and one of them has the trait.

25% is the probability that the female is a carrier for the trait. So, the correct option is (A).

What is Colourblindness?

Color blindness is defined as a reduced ability to differentiate between colors compared to the norm of normal human color vision. It is also called color vision deficiency (CVD) when a person is color blind, usually having difficulty distinguishing between certain colors such as yellow and orange, green and brown, pink and grey, or blue and green. Purple. These are typical of what is called "red-green color blindness".

The genes that can give red-green color blindness are passed on the X chromosome, although it is passed on the X chromosome, red-green color blindness is more common in males, causing males to inherit it from their mothers. There is only 1 X chromosome.

In the above case, if the mother is not colour blind but her son is color blind so, the probability for her daughter is 25%.

Thus, 25% is the probability that the female is a carrier for the trait. So, the correct option is (A).

Answers

Answer:

Explanation:

It's not necessarily that a large forest can only have a small population of wolves because a larger population will not affect the ecosystem that much but it just depends on the area. One forest may have more prey than others which the wolves rely to eat and stay healthy.  So yes it would be preferred to have a smaller population but again, it doesn't hurt to have a large one either. The main problem with having a larger population of wolves can be one of two issues;

Photosynthesis makes use of light energy while chemosynthesis is the main source of energy capture where light energy is not available.

What is photosynthesis?

It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy  through the process of cellular respiration.

Some of the energy which is converted  is stored in molecules of carbohydrates like sugar and starches  which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis  are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.

The process begins with proteins absorbing light energy  which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.
