Answer:
Our decisions have direct impact on the operations or actions of our body.
Explanation:
The decisions that we make each day greatly influence our body and efficiently our body operates because the activities we do in daily life put pressure on our body system. If our decisions force us to do hard work so it makes our body more stronger and healthier as compared to those decisions which requires no hard work so our body is not strong enough and our body can't operates efficiently.

What happens to predator populations when prey populations are scarce? Why?
Which of the following statements correctly identifies and describes the type of covalent bond found between
oxygen and hydrogen in water molecules?
hydrogen bonds because hydrogen is more electronegative than oxygen
O polar covalent bonds because oxygen is more electronegative than hydrogen
O polar covalent bonds because hydrogen is more electronegative than oxygen
Answer: O polar covalent bonds because oxygen is more electronegative than hydrogen
Explanation:
In the water molecule the two hydrogen atoms and one oxygen atoms forms the chemical structure in this the covalent bond is formed between hydrogen and oxygen and this is formed due to sharing of electrons between hydrogen and oxygen and oxygen being electronegative requires two electrons to complete its valency which are provided by two electrons each from one hydrogen and the O polar covalent bond is formed by this way.

The thin outer layer of the skin is called the _____.
endodermis
dermis
fatty layer
epidermis
The thin outer layer of the skin is known as the Epidermis. So, the correct option is D.
What is Epidermis?The epidermis, which is referred to as the skin's outermost layer, shields the body from the elements. Depending on the kind of skin, the epidermis can be as thin as.05 mm on the eyelids or as thick as 1.5 mm on the palms and soles of the feet.
The body is shielded by the epidermis from harmful substances like chemicals, pathogens (bacteria, viruses, fungus, and parasites), and ultraviolet (UV) radiation. The epidermis, which is the skin's outermost layer and gives skin its tone, serves as a waterproof barrier. The dermis, which lies underneath the epidermis, is made up of hard connective tissue, hair follicles, and sweat glands.
Thus, the correct option is D.

However, a damaged ____________ can regenerate if the ____________ remains intact and a critical amount of ____________ remains. The success of peripheral nervous system axon regeneration depends upon two primary factors: (1) the amount of ____________ and (2) the ____________ between the site of the damaged axon and the ____________ . The possibility of repair is ____________ with an increase in either of these two factors. Neurolemmocytes play an active role in regeneration
Answer:
The correct answer is - damaged, effector organ, neurilemma, damage, distance, cell body, decreased.
Explanation:
PNS axons are prone to cuts, and other types of injuries. A damaged axon can regenerate if the effector organ remains intact and a critical amount of neurilemma is found.
The degree of success of these axons regeneration depends upon factors that are (1) the amount of damage, and (2) the distance between the site of the damaged axon and the cell body it innervates The possibility of repair is reduced with an increase in either of these two factors. Neurolemmocytes play an active role in regeneration
Which critter trait is affected by an environmental factor, such as light, temperature, or
diet? Explain.
Answer:
Tallness.
Explanation:
Tallness is the critter trait that is affected by an environmental factor, such as light, temperature, or diet because the organism remains short if they are not getting food properly as well as temperature. Food provides essential nutrients that contribute in the growth of organism. Suitable temperature of the body allows the different functions in the body to be done which directly affects the growth of the body and the organism becomes taller.

Calculate the number of neutrons in atoms of the isotope 3919K
With working out
Answer:
20 neutrons
Explanation:
In the atom of an element, there exists three subatomic particles namely; proton, neutron and electron etc. The sum of the number of neutrons and number of protons (a.k.a atomic number) in an atom makes up the mass number.
In this question, an element was given as follows: 39- 19 K meaning that the mass number is 39 but the atomic number is 19.
Hence,
no of. neutrons = mass no. - atomic no.
39 - 19 = 20 neutrons.
The islets of Langerhans are surrounded by
A-exocrine cells that produce digestive fluid.
B-endocrine cells that produce digestive fluid.
C- exocrine cells that produce glycogen
D-B and C
PLEASE HELP ME ITS REALLY URGENT CAUSE I HAVE EXAMS TOMORROW!!!
Answer:
A-exocrine cells that produce digestive fluid.
Explanation:
The pancreas is composed of both exocrine cells (capable of producing digestive enzymes) and endocrine cells (involved in the production of hormones that control glucose homeostasis). The islets of Langerhans are clusters or 'islands' of pancreatic endocrine cells, which consist of α-cells that produce glucagon, β-cells that secrete insulin and δ-cells that produce somatostatin. These islets are surrounded by: 1-exocrine cells called 'acini' that produce digestive enzymes such as chymotrypsin, trypsinogen, lipase, and elastase; and 2-bile ductules, which are tubes that carry bile from the liver and the gallbladder through the pancreas.

Answer:
A phospholipid
a. has both polar and nonpolar regions.
Explanation:
Phospholipids, as amphipathic molecules, consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged hydrophilic (water-loving) polar head, which face outward and are attracted to the intracellular and extracellular fluid. The fatty acids are the uncharged, hydrophobic (water-fearing) nonpolar tails, which face the inside, away from the water and meet in the inner region of the membrane.

7. Based on their shape, how would you classify these Fungi? (Which Division do they fit?) I would classify them as sac fungi
Answer:
To match the features and characteristics.
Explanation:
We can classify these Fungi on the basis of their features and characteristics that resembles to the different divisions of fungi. Fungi are classified in four divisions i.e. the Chytridiomycota (chytrids), Zygomycota (bread molds), Ascomycota (yeasts and sac fungi), and the Basidiomycota (club fungi). There are specific characteristics of every division of fungi so we have to match the physical features of unknown fungi with these divisions and classify them.

HIV & AIDS. Is this condition still relevant? What are the latest statistics on this condition and can the new drugs really prevent new
infections?
Answer:
They're still VERY relevant.
Explanation:
In 2019, an estimated 34,800 new HIV infections occurred in the United States. HOWEVER new HIV infections declined 8% from 37,800 in 2015 to 34,800 in 2019. In 2012, the US Food and Drug Administration gave the green light to using daily pills of an HIV medication called Truvada (emtricitabine/tenofovir) to prevent infection. It proved more than 85% effective when taken on schedule. New drugs are still being developed, here's a link from the

What is the answer with explaining
Answer:
EeWw
Explanation:
The allele for the earlobe is depicted as e while that of the hairline is w.
A parent that is homzygous recessive for earlobes (ee) and homzygous dominant for hairline (WW) would have the genotype eeWW.
The other parent that is homzygous dominant for unattached earlobes and homzygous recessive for hairline would have the genotype EEww
eeWW x EEww
During meiosis, each genotype will form gametes.
eeWW: eW, eW, eW, eW
EEww: Ew, Ew, Ew, Ew
These gametes will randomly unite during fertilization to produce offspring. Since the same gametes are formed by each parent:
eW x Ew
offspring
100% EeWw (see the attached image for the Punnet's square)
The genotype of all the children would be EeWw and would phenotypically be with unattached earlobes and dominant hairline.
