A cell that is placed in distilled (plain) water will swell up because it fills
with water. Which process causes the cell to swell?
Answer:
If a cell is placed in a hypotonic solution, water will move into the cell. This causes the cell to swell, and it may even burst. A hypertonic solution means the environment outside of the cell has more dissolved material than inside of the cell. If a cell is placed in a hypertonic solution, water will leave the cell.

It helps to provide evidence by knowing the locations because of the settlemets that could also be there from the same species.
What might happen at the cellular level of the plant if there was no water available for photosynthesis?
Answer:
when water levels are low due to water stress, photosynthesis can slow or even stop, causing internal food supplies vital to other processes to diminish or disappear -- yellowing may also occur if photosynthesis stops completely.
Explanation:
If there was no water available for photosynthesis, the cellular level of the
plant will be affected negatively in areas such as shrinking of cells and
decrease in photosynthetic activities.
Plants require water to produce food in the process known as
photosynthesis. When there is no water the photosynthesis is slowed down
and the cells begin to shrink.
The shrinking of cells then results to the wilting and yellowing of leaves of the plant.

What are three kinds of volcanoes? What makes them different?
Answer:
Composite, shield, cinder cones, and supervolcanoes are the main types of volcanoes.
Composite volcanoes are tall, steep cones that produce explosive eruptions.
Shield volcanoes form very large, gently sloped mounds from effusive eruptions.
Volcanoes have several shapes, which are controlled by the composition of the magma and the nature of its eruption. If a volcano produces very fluid lava (low in the compound SiO2, or silica), the magma flows a long distance before it cools, making a flat, shield-shaped volcano.

The instructions, or 'code', in our DNA is dependent upon the order of the _____ in the DNA
-phosphates
-proteins
-bases
- sugars
Answer:
C. Bases
Explanation:
Deoxyribonucleic acid, commonly known as DNA, is the a type of nucleic acid that serves as the genetic material in living organisms. DNA holds information or instructions needed for the synthesis of useful products like proteins that is responsible for growth, reproduction, and general survival of organisms. Hence, it is referred to as the "BLUEPRINT OF LIFE".
However, in the structure the of the DNA molecule, it contains certain monomeric building blocks called NUCLEOTIDES. These nucleotide bases are of four types namely: Adenine, Thymine, Guanine and Cytosine. It is upon these order of nucleotide bases that instructions, or 'code', in our DNA is dependent upon.

This soil sample is the LEAST porous?
True or false
Answer:
False
Explanation:
Soil with least porosity
Thus, the correct answer is 'Clay soil. '
There are other types of soil that can be more crumbly, but this is not the least. Because porous means something is full of tiny holes or openings, you can see that this is the right word to match it with! The least crumbly, or porous would only have a little crack. Good luck, and I hope this helped!
Also....
Clayey soil is the least porous.
Clayey soil is the least porous soil as the spaces between the molecules of the soil is less and water cannot pass through them.

I’ll give brainiest:)
Answer:
The answer is C
Explanation:
I just got it right on the quiz
Fructose feeds sperm, enabling them to survive long enough to fertilize an egg.
Semen contains fructose because it feeds the sperm, enabling them to survive long enough to fertilize an egg. Therefore, the correct answer is option C.
What is fructose?Fructose is a type of sugar that provides energy to the sperm as they travel through the female reproductive tract in search of an egg to fertilize. Sperm have a limited lifespan outside the male body, so it is essential that they are supplied with enough energy to reach and fertilize an egg before they die.
The fructose in semen provides this energy to the sperm, allowing them to survive and swim towards the egg. Once inside the female reproductive tract, the fructose is absorbed by the sperm and used to fuel their movement towards the egg. Without the fructose in semen, the sperm may not have enough energy to reach the egg and fertilize it.

Transcribe and translate the following DNA strand into an RNA strand: TACCA
GTAGATT
Answer:
Explanation:Key points:
Transcription is the first step in gene expression. It involves copying a gene's DNA sequence to make an RNA molecule.
Transcription is performed by enzymes called RNA polymerases, which link nucleotides to form an RNA strand (using a DNA strand as a template).
Transcription has three stages: initiation, elongation, and termination.
In eukaryotes, RNA molecules must be processed after transcription: they are spliced and have a 5' cap and poly-A tail put on their ends.
Transcription is controlled separately for each gene in your genome.
Introduction
Have you ever had to transcribe something? Maybe someone left a message on your voicemail, and you had to write it down on paper. Or maybe you took notes in class, then rewrote them neatly to help you review.
As these examples show, transcription is a process in which information is rewritten. Transcription is something we do in our everyday lives, and it's also something our cells must do, in a more specialized and narrowly defined way. In biology, transcription is the process of copying out the DNA sequence of a gene in the similar alphabet of RNA.
Overview of transcription
Transcription is the first step in gene expression, in which information from a gene is used to construct a functional product such as a protein. The goal of transcription is to make a RNA copy of a gene's DNA sequence. For a protein-coding gene, the RNA copy, or transcript, carries the information needed to build a polypeptide (protein or protein subunit). Eukaryotic transcripts need to go through some processing steps before translation into proteins.
In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complementary RNA transcript. The other strand, the coding strand, is identical to the RNA transcript in sequence, except that it has uracil (U) bases in place of thymine (T) bases.
Example:
Coding strand: 5'-ATGATCTCGTAA-3'
Template strand: 3'-TACTAGAGCATT-5'
RNA transcript: 5'-AUGAUCUCGUAA-3'
For a protein-coding gene, the RNA transcript contains the information needed to synthesize a polypeptide (protein or protein subunit) with a particular amino acid sequence. In this case:
RNA transcript (acting as messenger RNA): 5'-AUGAUCUCGUAA-3'
Polypeptide: Met-Ile-Ser-STOP
In transcription, a region of DNA opens up. One strand, the template strand, serves as a template for synthesis of a complementary RNA transcript. The other strand, the coding strand, is identical to the RNA transcript in sequence, except that it has uracil (U) bases in place of thymine (T) bases.
Example:

RNA transcript (acting as messenger RNA): 5'-AUGAUCUCGUAA-3' Polypeptide: Met-Ile-Ser-STOP
RNA polymerase
The main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA. Specifically, RNA polymerase builds an RNA strand in the 5' to 3' direction, adding each new nucleotide to the 3' end of the strand.
RNA polymerase synthesizes an RNA strand complementary to a template DNA strand. It synthesizes the RNA strand in the 5' to 3' direction, while reading the template DNA strand in the 3' to 5' direction. The template DNA strand and RNA strand are antiparallel.
RNA transcript: 5'-UGGUAGU...-3' (dots indicate where nucleotides are still being added at 3' end)
DNA template: 3'-ACCATCAGTC-5'

Stages of transcription
Transcription of a gene takes place in three stages: initiation, elongation, and termination. Here, we will briefly see how these steps happen in bacteria. You can learn more about the details of each stage (and about how eukaryotic transcription is different) in the stages of transcription article.
Initiation. RNA polymerase binds to a sequence of DNA called the promoter, found near the beginning of a gene. Each gene (or group of co-transcribed genes, in bacteria) has its own promoter. Once bound, RNA polymerase separates the DNA strands, providing the single-stranded template needed for transcription.
