Parasitism. Ticks are complete parasites with no regard for the well being of their carriers.
What shape is the sugar in a nucleotide?
Answer:
In double-stranded DNA, the molecular double-helix shape is formed by two linear sugar-phosphate backbones that run opposite each other and twist together in a helical shape. The sugar-phosphate backbone is negatively charged and hydrophilic, which allows the DNA backbone to form bonds with water.
1-2 Paragraphs About The Background Of Reaction Time Slowing Down Once You Get Older
Answer:
Reaction times slow with age, and they correlate with scores on tests of higher cognitive functions many of which also deteriorate with age. The age-related changes in reaction times account for a substantial proportion of the age-related variance in higher cognitive functions (e.g., Deary, 2000. 2000Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. ... But the effect of age on reflexes and reaction time varies greatly from person to person. You can actually slow down—even reverse—the effects of aging by staying physically active.The next time some twenty-something complains that they feel old, you can reassure them that their feelings are, in fact, not ridiculous. After studying 3,305 people ages 16 to 44, researchers found that the brain's response time begins to decline at age 24.

What are the ecological roles of annelids?
ANSWER ASAP!
I’ll mark you as brainliest..
Answer:
The most important function of annelids, or earth worms, to their ecological environment is to turn over the soil, making it healthier for plant life. This is accomplished both by their burrowing habits and through eating and excreting dirt.

Cells genetically unique is it mitosis or meisis
Answer:
Meiosis
Explanation:
While mitosis makes two identical cells with the same numbers of chromosomes, meiosis makes four unique daughter cells, from which every cell has half of the number of the chromosomes as the parent cell.
Meiosis is the specified form of cell division, making the reproductive cells, like sperm and egg cells, for example.
(50 points)The picture is a cross section of a bone.
A cross sectional view of bone. X points to the inner layer. Y points to the middle layer.
Which structures of the bone are indicated by the arrows?
A. X-compact; Y-spongy
B. X-spongy; Y-marrow
C. X-spongy; Y-compact
D. X-marrow; Y-spongy
Answer:
it is b X-spongy; Y-marrow, i am doing the test, and the other person is correct.
Explanation:
The arrows point to the bone formations called X-marrow and Y-spongy. So, the correct option is D.
What are Compact and spongy bones?Osteons or haversian systems are tightly packed together to form compact bone. The osteon is made up of concentric circles (lamellae) of matrix surrounding a central canal known as the osteonic (haversian) canal. The bone cells (osteocytes), which are situated between both the rings of matrix, are found in regions known as lacunae.
The bone marrow stores fat and produces blood cells. Spongy bone, also known as cancellous bone, is composed of tiny, needle-like bone fragments organized in a honeycomb pattern. Bones that are more flexible can still be strong while weighing less. In the given example, the arrows indicate to a X-marrow and Y-spongy bone structures.
Therefore, the correct option is D.

A student observers melting crayons. Which of the following describes what they saw? A. A chemical change. B. A physical change. C. A physical property. D. A chemical property
Answer: A physical change
Explanation: since the melted they are still Crayons. You can freeze it and it would still be a crayon. So it was only a physical change
Which of the following best explains how insulin injections affect signal transduction in an individual with type 1 diabetes
A. They serve as second messengers to regulate glucose uptake to cells
B. They allow alternate signaling transduction pathways to control glucose levels
C. They open channels to allow signaling molecules to enter pancreatic cells
D. They provide a signaling molecule to begin the signal transduction pathway
Answer:
The correct answer is - option A. They serve as second messengers to regulate glucose uptake to cells.
Explanation:
Type one diabetes is a condition that is characterized as the inability to produce enough quantity or at all of the insulin by the beta cells of the pancreas. Therefore, a patient with this condition completely depends on exogenous insulin to maintain the sugar level in the blood.
Insulin is the hormone that removes the excess amount of glucose from the blood by the adipose tissue, liver cells, and skeletal muscle that uptake an extra amount of sugar. there are receptors present on the surface of the plasma membrane which binds with the insulin and acts as a secondary to regulate a cascade reaction to glucose uptake to cells.

Summarize the 3 types of cell division: Binary fission, mitosis, and meiosis
Answer:
Binary Fission is the reproduction of prokaryotic cells (bacteria and bacteria-like Archaea) is accomplished through binary fission. Binary fission is essentially cloning. Barring mutations that may have occurred when the genetic material was copied (a process called replication), the two resulting daughter cells are identical to the parent cell.
Mitosis is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information.
8. The heart is considered to be a part of which of the two systems listed below? A circulatory and integumentary C circulatory and muscular B respiratory and muscular D skeletal and circulatory
I found this i hope it helps
About the Heart and Circulatory System
The circulatory system is composed of the heart and blood vessels, including arteries, veins, and capillaries. Our bodies actually have two circulatory systems: The pulmonary circulation is a short loop from the heart to the lungs and back again, and the systemic circulation (the system we usually think of as our circulatory system) sends blood from the heart to all the other parts of our bodies and back again.
Pls help me , if I get this right I get a A

HURRY PLEASE HELP I REALLY NEED THE ANSWERS Briefly describe the three layers
of the mantle. Include
temperatures.
•Lithosphere:
•Asthenosphere:
•Mesosphere:
Answer:
lithosphere
Explanation:
is up of brittle crust and the top part of upper mantel and also the coolest and most rigid part of the earth
Answer:
Lithosphere:
The lithosphere is the rigid outermost layer of the earth known as the mantle and the crust. And it is defined by its rigid mechanical properties.
Asthenosphere:
This layer is highly viscous and is very mechanically weak and is located below the Lithosphere it is also known as the ductile region of the upper mantle.
Mesosphere:
The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases.
