An apple, potato, and onion all taste the same if you eat them with your nose plugged
Answer:
the flavor will neutralize
Explanation:
if you're plugging your nose, it blocks most of the taste out of a food item. so while biting into an onion while plugging your nose, it will neutralize the strong flavor and make it taste more like an apple or potato since they have very similar textures. hope this helps!
true or false? a haploid organism has one pair of homologous chromosomes.
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.

Which argument supports that humans and other animals depend on plants for survival?
Answer:
Animals are totally dependent on plants. First of all plants produce oxygen which is vital for life on earth. Then, for many animals plants are their basic food, or if plants don’t make up 100 % of their diet, plants are nevertheless essential in their food supply. Plants are also used by animals (and men) as material for building nests (and or homes). Carnivorous animals eat animals which are herbivorous, and without plants they wouldn’t survive, so the carnivors would quickly disappear. Plants are also vital in the maintaining of the climate and without plants the earth’s surface would be subject to erosion. So, to resume, life on earth wouldn’t be possible without plants.

Describe three ecosystem services that insects provide?
Answer:
dung burial, pest control, and pollination
The three ecosystem services that insects provide are dung burial, pest control, and pollination.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.

what percentage of genetic information is passed on from parents to their offspring
Answer:
50% from each parent
Explanation:
The percentage of genetic information passed on from parents to their offspring is 50% from each parent, for a total of 100%.
What is the percentage of genetic information?Approximately 50% of genetic information is passed on from each biological parent to their offspring. This occurs through the combination of genetic material during fertilization, where half of the offspring's genetic material comes from the mother and the other half from the father.
However, the exact percentage of genetic information passed on can vary due to factors such as genetic mutations and recombination during meiosis.
This occurs through the process of sexual reproduction, where each parent contributes one gamete (sperm or egg) containing half of their genetic information.
When the sperm and egg combine during fertilization, they form a zygote with a complete set of genetic information (100%), half from each parent.

Which statement is a hypothesis that would best address the question "Are rainbow trout eating all the macroinvertebrates in streams and starving out other fish species?" If rainbow trout are eating all the macroinvertebrates, then keeping rainbow trout out of new river habitats will allow native species to recover. If rainbow trout are eating all the macroinvertebrates, then introducing them to other streams will help native species recover. Rainbow trout will eat a variety of macroinvertebrates and native fish species. Rainbow trout hunt and prey upon native fish species.
A possible hypothesis here is; "If rainbow trout are eating all the macroinvertebrates, then keeping rainbow trout out of new river habitats will allow native species to recover."
A hypothesis is a statement that is tentatively put forward to explain an observation. Usually, a hypothesis is an if .... then statement. This is one of the first things that we must look out for when considering each of the statements.
Since we have observed that rainbow trout eating all the macroinvertebrates in streams and starving out other fish species, it follows that keeping rainbow trout out of new river habitats will allow native species to recover."

what would happen to a signaling pathway if phosphatases had reduced levels of function?
if blood calcium levels drop below 8.5 mg/dl which hormone is likely to be activated?
Answer:
Parathyroid Hormone (PTH)
Explanation:
The major function of the parathyroid glands is to maintain the body’s calcium level in both the blood and bones.
There is a narrow range of calcium required for the nervous and muscular systems to function properly. (A normal calcium level in the blood stream ranges from 8.5-10.2 mg/dL ).
When blood calcium levels drop below a certain level, receptors in the parathyroid gland release parathyroid hormone (PTH) in proportion to the amount of calcium that is required by the body. This hormone increases blood calcium levels by stimulating osteoclasts to release calcium by breaking down bone. Osteoclasts are cells in the bones that break down and remodel bone tissue.

Answer:
Here is the answer to your question.
Explanation:
Chlamydomonas: Motile unicellular algae, generally oval, cell wall is made up of a glycoprotein and non-cellulosic polysaccharides instead of cellulose, two anteriorly inserted whiplash flagella, contractile vacuoles are near the bases of flagella.
Amoeba: Amoeba is a unicellular organism found in stagnant water, the size of amoeba is 0.25, they move with the help of a finger-like projection called pseudopodia, the cytoplasm is differentiated into two parts, the outer portion is ectoplasm and the inner portion is called endoplast, amoebae are eukaryotes whose bodies most often consist of a single cell.
Paramecium: Paramecia cells are characteristically elongated, Paramecia are eukaryotes, asexual reproduction (binary fission), sexual reproduction (conjugation), autogamy (self-fertilization).
Diatom: Diatoms have two distinct shapes: a few (centric diatoms) are radially symmetric, while most (pennate diatoms) are broadly bilaterally symmetric. A unique feature of diatom anatomy is that they are surrounded by a cell wall made of silica (hydrated silicon dioxide), called a frustule.
