Considering that cells vary in shape,what other dimensions or parameters of the cell could be used to estimate cell size?
Answer:
Three general factors determine cell shape: the state of the cytoskeleton, the amount of water that is pumped into a cell, and the state of the cell wall. Each of these three factors is highly dynamic, meaning they are constantly in flux or can be suddenly changed. This dynamism is how cells can vary in shape.

Yeast cells are eukaryotic. What does this mean? in your own words
Answer:
Yeast cells are eukaryotic which means that they have a membrane-bound nucleus that holds their genetic information.
Eukaryotic cells also contain membrane-bound organelles such as:
Mitochondria responsible for energy productionRibosomes responsible for protein synthesisCell wall that protects the cell from the environmentThe Golgi apparatus that packages proteinsIt also means that their cellular complexity is different from Prokaryotic organisms which lack membrane-bound structures for example the nucleus. Prokaryotic cells are mostly small and simple and Eukaryotic cells are typically a lot bigger and more complex.

Three kinds of _________ molecules carry out genetic instructions for the production of proteins?
Explain the importance of scientific names.
Answer:
Every recognized species on earth (at least in theory) is given a two-part scientific name. This system is called "binomial nomenclature." These names are important because they allow people throughout the world to communicate unambiguously about animal species.
A red flower RR and a purple flower BR have 4 offspring how many will be red blue and purple? Complete a Punnett square
Answer:
So three of the offspring will be red, blue and purple and one will be purple.
hope that's correct and it helps
This question is in accordance with the mendel law of independent assortment which stated that two alleles assort independently during gamete formation. Therefore, the resultant punnett square will show flower having the genotype of RB and purple color as its phenotype. See Attachment for punnet square results.
the enzyme dicer chops dsrna molecules into small pieces of
The enzyme dicer chops dsRNA molecules into small pieces of miRNA and siRNA. The correct option is B.
What is Dicer?
Dicer is an enzyme involved in RNA interference (RNAi), a cellular process that regulates gene expression.
Its primary role is to cleave double-stranded RNA (dsRNA) molecules into smaller fragments.
These fragments are typically around 21-25 nucleotides in length and serve as the building blocks for two types of small RNA molecules: microRNA (miRNA) and small interfering RNA (siRNA).
miRNAs are endogenous small RNA molecules that play a crucial role in post-transcriptional gene regulation. siRNAs are also small RNA molecules but are primarily involved in the defense against viral infections and the silencing of transposable elements.Thus, the correct option is B.

Hormones exert an effect only on a gland or organ that has a ________ where that specific hormone can bind.
Hormones excite, inhibit, or regulate the activity of other organs when they exert their effect on a target cell where that specific hormone can bind.
A hormone is the substance secreted by certain glands that promotes, blocks or regulates the activity of the organs.
Target cells are cells that possess specific receptors for hormones on their surface.The recognition of a hormone by its target cell lies in the presence at the cellular level of glycoproteins, called receptors, which bind specifically to the hormone, with high affinity and in a reversible way.Receptors present some differences related to the type of hormone or neurotransmitter to which they bind, with their location in the cell and with the way of transferring information after their union with these molecules.Therefore, we can conclude that hormones are produced by certain glands, circulate through the blood and reach other cells called target cells, exerting a regulatory effect on them.

Although scientists do not know the exact origin of eukaryotic cells, the ______ theory does explain the origin of the mitochondria and chloroplasts.
Explanation:
The Endosymbiotic Theory states that the mitochondria and chloroplast in eukaryotic cells were once aerobic bacteria (prokaryote) that were ingested by a large anaerobic bacteria (prokaryote). This theory explains the origin of eukaryotic cells.

Describe the path of a phosphorous atom through four parts of the phosphorous cycle. Be sure to explain the processes involved in the transfers. Note when a form of phosphorous is available to plants. (Will mark brainliest)
Answer: One of the ways the path of a phosphorous atom starts is in a rock containing phosphate. The rock weathers, so that a phosphate ion enters the soil. A plant takes up the phosphate ion and incorporates it into a DNA molecule in a pollen grain. The grain falls back to the ground and decomposes, converting the atom back into phosphate through mineralization. The phosphate ion then leaches into the groundwater, leaving the soil.
Explanation: Plato/ Edmentum
Phosphorus moves in a cycle through rocks, water, soil and sediments, and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals.
This inorganic phosphate is then distributed in soils and water. Plants take up inorganic phosphate from the soil.
How does phosphorus enter the phosphorus cycle?
Phosphorus enters the atmosphere from volcanic aerosols. As this aerosol precipitates on earth, it enters terrestrial food webs. Some of the phosphorus from terrestrial food webs dissolves in streams and lakes, and the remainder enters the soil. Another source of phosphorus is fertilizers.

By the late 1830s, botanist Matthias Schleiden and zoologist Theodor Schwann were studying tissues and proposed the unified cell theory. The unified cell theory states that: all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells.

What does an alcoholic beverage contain that is a central nervous system depressant? 
Answer:
interferes with release of neural transmitter GABA
Explanation:
Alcohol is a central nervous system depressant, meaning it slows down brain functioning and neural activity. Alcohol does this by enhancing the effects of the neural transmitter GABA
depressants essentially "look" like the neural transmitter and so they go in and block the plasce in the brain between synapses, so when the body tries to release GABA, it appears as if it is already filled in, but in reality it is the alcohol that has filled it. once they start buidling up, they block enough that it impairs brain activity
Answer:
GABA
Explanation:
gamma-aminobutyric acid (GABA)
Just for the fun of it, someone walking along the shore in Beaufort, South
Carolina, throws a bottle with a message in it into the sea. Some time later,
someone in Perth, on the west coast of Australia, finds the bottle.
Referring to map, trace the path the bottle probably took! Make sure to
reference specific currents on your path.
The currents that carry the bottle from South Carolina to Peth are the West Wind Drift and the South Equatorial Current.
According to the information provided by the map, it can be inferred that the bottle that is thrown into the sea in South Carolina, USA and arrived in Perth, Australia took the following route:
It traveled down the Atlantic Ocean from the United States to the West Wind Drift current. Once there, it is transported from the west to the east, passing through the lower part of Africa and Asia until it reaches the Indian Ocean. When it reaches the Indian Ocean it is carried by the South Equatorial Current with a northeast direction. In this direction it reaches the coast of Peth, Australia.
