Which is an example of a parasite and host relationship? A) a chlorophyll and a green plant B) a wolf and a rabbit C) a tapeworm and a human D)sunlight and green plants
Answer:
C) a tapeworm and a human
Explanation:
A parasitic relationship is defined as the relationship between two organisms in which one organism called parasite fed over other organism called host and parasite get benefits while the host get harmed.
From the given options, relationship between a tapeworm and a human is a parasitic relationship because a tapeworm act as a parasite in human body. Parasite gain food or nourishment while human body loses its nourishment.
Hence, the correct answer is "C) a tapeworm and a human".

Explain why oxygen and carbon dioxide diffuse in opposite directions in the lungs?
Answer:
There is a higher oxygen content in the air of the lungs than that of oxygen-depleted blood and a lower carbon dioxide concentration. This gradient of concentration causes gas exchange during respiration.

the parathyroid _____ blood calcium by taking the calcium from the _____
Answer:
Parathyroid hormone is secreted by the parathyroid glands and is the most important regulator of blood calcium levels.
The parathyroid maintains blood calcium by taking the calcium from the bones.
What is the parathyroid gland?The body requires exact calcium levels since even tiny variations can lead to problems with muscles and nerves. The following processes are stimulated by the parathyroid hormone: bones' release of calcium into the blood. The intestines' absorption of calcium from meals.
The thyroid glands create the parathyroid hormone, which aids in preserving the appropriate level of calcium in the blood and in tissues that require calcium for optimal function.
This is particularly crucial for bone health as well as nerve and muscle function. The bones, kidneys, and small intestine are directly impacted by the parathyroid hormone.
PTH increases the release of calcium from the bones in an indirect manner through osteoclasts, which eventually results in bone resorption.
Therefore, parathyroid maintains blood calcium by taking the calcium from the bones.

What is a body function that would contribute to BMR?
Breaking down a burger in the stomach
O Catching a Frisbee
O Heart beating
O Wrestling a Grizzly Bear
Answer:
Breaking down a burger in the stomach.
Explanation:
Basal metabolic rate (BMR) also known as resting metabolic rate (RMR) can be defined as the amount of calories that is required to keep the human body to function properly and perfectly at rest.
This ultimately implies that, basal metabolism is the minimal amount of calories or energy that is required by an individual for maintaining vital functions such as blood circulation, keeping the body warm and respiration while fasting or in a complete mental and physical rest.
Some of the factors that affects the basal metabolism rate (BMR) in humans are height, weight, age, starvation or fasting, thyroxine, fever, stress, malnutrition and growth.
Hence, breaking down a burger in the stomach is a body function that would contribute to BMR.

During fermentation, how do changes to a molecule of pyruvic acid to lactic acid or ethyl alchol contribute to
the formation of ATP?
Answer:
Some organisms, such as some bacteria, will undergo lactate fermentation. Two pyruvates are converted to two lactic acid molecules, which ionize to form lactate. In this process two NADH + H+ are converted to two NAD+. Our muscle cells can undergo this process when they are in oxygen debt.

Answer:
A. Miosis
B. DNA molecule
C. Body cells
D. phenotype
E. Recessive traits
F. genotype
G. Punnet square
H. nondisjunction
I. mitosis
J. sex cells
Explanation:
In meiosis cell division, a parent cell divides into four daughter cells whereas in mitosis, one cell divides into two daughter cells. If change occur in DNA molecules, mutation occurs. Phenotype refers to physical characteristics of an organism whereas genotype indicates genetic characteristics. Recessive traits only appears when the organisms have same traits or allele. Somatic cells is known as body cells whereas gametes is known as sex cells.

The correct answer is - increase in the number during this period in the lake which suggests there are plenty of resources during this period required for the growth of the algae.
Explanation:
In the given graphical representation, there is a continuous increase in the number of algae present in the lake during the period of time between February to June. There is some fluctuation found in mid-April and early June but it is negligible.
This continuous increase in the number of algae suggests that during this period the resources are in abundance that affects the growth of the alage.

Give at least two examples. will mark brainleist!
Answer:
1. Red blood cells: It produces hemoglobin, an oxygen-carrying protein.
2. White blood cells: It produces soluble protein called antibodies.
3. Muscle cell: It produces the muscle protein known as myosin.
Explanation:
The above are some of the specialized cells in multicellular organism. The red blood cell is in charge of carrying oxygen in the body. It contains/produces hemoglobin which is the protein the cell also produces. The hemoglobin also gives the blood cell its red color.
The white blood cell, also known as leukocyte is the component of the blood cell which defends the body against infections. The cell is highly mobile within the body and moves to the site of infection in order to defend it. It produces antibodies that actually defend the body against infections.
The muscle cell are the cells within the human body that help to make the movement of cell to be possible. It produces myosin which also combines with actin, another muscle protein.
