Answer:
False
Explanation:
A haploid has one SET of homologous chromosomes
It is false that a haploid organism has one pair of homologous chromosomes.
What are haploid organisms?When an organism's cells only have one set of chromosomes, the organism is said to be haploid.
All organisms that reproduce are diploid (having two sets of chromosomes, one from each parent). Only the egg and sperm cells in humans are haploid.
Male ants, bees, and wasps are haploid organisms because they develop from unfertilized haploid eggs, whereas females (workers and queens) are diploid, making their system haplodiploid. The majority of animals are diploid.
The term "diploid" describes how many complete sets of chromosomes there are in each cell of an organism: diploid cells have two entire sets.
On the other hand, haploid organisms only have one complete set of chromosomes. Throughout meiosis and sporadically in mitosis, chromosome sets can change.
Thus, the given statement is false.

What type of epithelial cells would you likely find on the surface of mucous membranes? Explain why
Answer:
simple columnar epithelial tissue or Stratified squamous nonkeratinized epithelium

What problems do animal cells have since they don't have cell walls?
Answer:
These antibiotics bond to protein molecules on the existing wall and prevent the cell from adding any new material as the wall stretches. When the cell wall stretches too far, it becomes weak and eventually bursts, destroying the cell. Since animal cells don't have cell walls, they are not affected by penicillin.

Which traits in the investigation showed incomplete dominance?
Answer:
A child born with semi-curly/wavy hair
Explanation:
A child born with semi-curly/wavy hair is individuals exhibiting incomplete dominance because the crossing of parents alleles both straight and curly hairs to produce such offspring. Thus, incomplete dominance occurs to produce an intermediate trait between the two parent traits.

In a 200m race, athletes sprint the entire length. What type respiration is most likely occurs near the finish line.
Alcoholic fermentation
Photosynthesis
Aerobic respiration
Latic Acid Fermentation
Answer:
Running can take many forms, from a leisurely jog to an all-out sprint. But no matter what kind of running you do, your body needs to power itself through respiration. Lighter, long-distance running causes your body to use aerobic respiration, while more intense sprinting and interval training requires anaerobic respiration.

how much land is louisiana losing every year as a result of coastal erosion?
Louisiana is losing about 16 square miles/year as a result of coastal erosion. This estimation is a variable as the rate of coastal erosion varies from time to time.
Coastal erosion is the process through which local sea-level rise as a result of intense wave action in coastal sea levels which deteriorate over time along the shore.
In Louisiana, coastal erosion results in the depletion of wetlands via the routes of coastal lines in swamps and marshes. Storms and other natural occurrences that induce erosion impact all coasts. The combination of storm surge at high tidal waves with additional effects from large waves, as well as circumstances often associated with landfalling tropical severe storms, provides the most devastating conditions in landfilled regions.
Therefore, the amount of landmass lost by Louisiana is estimated to be 16 square miles/year as a result of coastal erosion.

The cell membrane's function is to..
O allow nutrients in, and send wastes out of the cell
O to control the amount of water that enters the cell
O to block all nutrients from entering the cell
Answer:
The first bullet point is correct
Explanation:
The cell membrane controls what comes in and out of the cell, it needs minerals so would not block them completely, and water does not enter cells so it is clearly the first one.
Which is NOT a homeostatic mechanism?
O fecal regulation
O water regulation
oxygen regulation
thermoregulation
Explanation:
To be precise, homeostasis is a process/phenomenon not a system. Homeostasis is actually the process of maintaining a stable internal environment despite changes in the external environment. There are mechanisms in organisms that regulate pH and this regulation is an example of homeostasis.

The characteristic of a nerve cell that relates directly to its function in receiving and
transmitting nerve impulses is its
a. long extensions.
c. ability to change shape.
b. flat shape.
d. ability to engulf and destroy bacteria.
The axon is the long cytoplasmic extension and the dendrons are the short cytoplasmic extensions. The extensions are responsible for receiving and the transmission of the nerve impulses. Thus, the correct answer is option A. Hope it's helpful to you !

The negative membrane potential in a resting neuron is primarily due to :___________
a. high levels of chloride ions in the cell. diffusion of potassium out of the cell.
b. a higher permeability of the membrane for potassium compared to sodium.
c. both diffusion of potassium out of the cell and a higher permeability of the membrane for potassium compared to sodium are correct.
Answer:
c
Explanation:
When the membrane of the neuron is in a state of rest, the interior of the cell has a more negative charge in relation to the exterior, therefore option "c" is correct.
What is the membrane potential in a resting neuron?It is a phenomenon that occurs when the nerve cell membrane is not altered by action potentials.
Characteristics of a resting neuronThe resting potential is determined by the concentration gradients of the ions, both inside and outside the neuron, and by the permeability of the membrane.When a cell is at rest, the potassium channels are open, the potassium will tend to flow outwards (K ions), they are positive charges, therefore the cell interior will be negative with respect to the cell exterior.Therefore, we can conclude that the resting potential of a membrane occurs when they are not transmitting signals.

Describe the significance of enzymes in our digestive system having different optimal pH and optimal temperatures. (Hint: What does this allow our bodies to do?)
Answer:
Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.
For most enzymes to operate in the body, the optimal temperature is 37 degree Celsius or 98 degrees Fahrenheit. Most of the human enzymes have a maximal activity at pH around 7.2, which is the pH of most body fluids. However, there are exceptions such as, pepsin.
