Answer:

Independent: Purposely altered

Dependent: Changes with respect to the independent being altered

Controlled: Never changes

Explanation:

An independent variable is a variable in which does not rely on other pieces/variables of an experiment to assume a value. In other words, it does not change when other variables change. However, it can be changed intentionally by the scientist.

A dependent variable is a variable in which its change in value relies on other pieces/variables of an experiment to assume a value. So, if the indeoendent variable is changed, the dependent variable will change as well. The opposite is not true though - if the dependent variable changes (for whatever reason), the independent variable hasn't necessarily been changed.

A controlled variable is a variable that stays CONSTANT throughout an experiment. It is never changed, and nothing will change it. An example of a control variable is the number of participants in a study: no more participants are being added, and no participants are being removed. The number of participants remains STATIC throughout the study.

zheka24 [161]

This is a case of a hypertrophic cardiomyopathy with preserved ejection fraction. A hypertrophied left ventricle is a echocardiographic sign that there is chronic stress put in the left ventricle, most commonly in overcoming high aortic pressures in patients with systemic hypertension. In this case, there is normal chamber volume and normal ejection fraction therefore the heart is functionally normal and ejection fraction is preserved.

Question 1

Nadya [2.5K]

Answer: Question 1 answer: Skin cells continually replicate

Explanation: The cells in the superficial or upper layers of skin, known as the epidermis, are constantly replacing themselves. This process of renewal is basically exfoliation (shedding) of the epidermis. But the deeper layers of skin, called the dermis, do not go through this cellular turnover and so do not replace themselves.

Question 2 answer: Heart cells undergo terminal differentiation

Explanation: Different cell types (e.g., neurons, skeletal and heart myocytes, adipocytes, keratinocytes) undergo terminal differentiation, in which acquisition of specialized functions entails definitive withdrawal from the cell cycle.

Question 3 answer: DNA replicates in the nucleus

Explanation: DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication.

Question 4 answer: The ability to reverse terminal differentiation might affect gene expression in a complex organism

Question 5 answer Cytoplasm replicates during mitosis

Explanation: This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. ... The outcome of binary fission is two new cells that are identical to the original cell.

OLga [1]

Answer

68.6 m

Explanation:

Given-

Mass = 0.5 kg
Potential energy = 34.3 J

To find -

Height of the tree upto which the squirrel climbed.

Solution-

Potential energy of a body = mgh

34.3 = 0.5×h (mg = 0.5kg)

h = 34.3/0.5

= 68.6 m

Option third.
