As a part of her homework, June make a flowchart about the steps involved in hearing the sound energy produced by wind chimes.

A flowchart with four steps. The first step is the rods vibrate back and forth. The second step is wind chime rods hit each other. The third step is sound waves are created. The fourth step is the sound travels into your ears.

Which statement best explains the error in June's flowchart?

The wind chime rods hit each other before they begin to vibrate.
Sound waves are created before the wind chime rods hit each other.
The sound of the wind chimes travels to your ear before the rods vibrate.
The spin of the rods causes sound energy, not its vibrations.

what gives animal cells their shape and structure?

Answers

Answer: Animal cell's shape and structure are determined by the cytoskeleton.

What is the cytoskeleton?

The cytoskeleton is present in all animal cells, prokaryotic (bacterial) cells contain a very rudimentary version of it, while plant cells do not have one at all. It consists of several types of large molecules that provide physical support to the cell as well as internal transport along its length for organelles like endoplasmic reticulum (ER), mitochondria, vacuoles, etc. The three main components are microtubules, intermediate filaments and microfilaments which give rise to different structures within the cell. Microtubules are long cylindrical tubes made up of two protein subunits (alpha and beta tubulin) that form a hollow tube. These are the main components of the cytoskeleton, they provide support to the cell while also having transport capacity for organelles like endoplasmic reticulum (ER), mitochondria, vacuoles, etc. Microtubules are dynamic structures which means their state is constantly changing i.e., growing, shrinking or moving around depending on requirements of the cell.

You are attempting to carry out a transposon mutagenesis experiment using the pRL27 system. The Donor strain you use was giving to you by a lab mate who has been culturing it continuously for several months. When you set up your control plates, you find that the Donor strain grows poorly on Luria DAP Agar. Your transformation efficiency is very poor for this attempt at mutageneis. What likely happened to the Donor strain

Answers

The most likely happened to the donor strain is that the transposon is active in the donor resulting in the gradual accumulation of mutations. The accumulation of mutations is promoted by the insertion of the transposon.

A donor strain is a bacterial strain that contains a mobilizable fragment of DNA called plasmid.

These strains (donor strains) exploit the transference properties of a conjugative plasmid to modify a particular recipient strain.

Transposons, also known as jumping genes, are mobile genetic elements that alter the genome of an organism by jumping and thus inserting them into genetic sequences (i.e., into protein-coding sequences).

In this case, the presence of a transposon in the donor strain affected the expression of many genes required for the donor strain in order to grow into Luria DAP Agar.

What are the differences between an onion and a whitefish cell

Answers

During mitosis, the animal cell will have visible centrioles, where the plant cell will not. In thin section slides, you will also see that the onion cells are all dividing along the same axis, while in the whitefish embryos the plane of division appears to be random.

Onion are something that you can eat and grow on trees while whitefish cells are a part of whitefish.

What is the main purpose for plants to conduct photosynthesis?

Answers

Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Explanation:

different types of cells in your body look and function differently. the basis for these differences is:

Answers

Different types of cells look and function differently, the basis for these differences is DIFFERENT PATTERNS of gene expression. This process (differential gene expression) leads to cell specialization.

Gene expression refers to the process by which the genetic information flows from a DNA sequence (i.e., a gene) to an mRNA molecule and finally to a protein.

In somatic (body) cells, the differential patterns of gene expression lead to the generation of different proteins and ultimately to different types of cells (cell phenotypes).

In consequence, cells are specialized to perform specific functions because different genes are being expressed.

Explanation:

Hope it helped

please mark as brainliest

In angiosperm double fertilization, one sperm nucleus fertilizes the egg to form the diploid zygote, and a second sperm nucleus fuses with the two nuclei in the central cell of the embryo sac.

The egg is the female gamete in an angiosperm. It is a haploid cell that contains one set of chromosomes. The zygote is the fertilized egg. It is a diploid cell that contains two sets of chromosomes. The zygote will eventually develop into an embryo. The central cell is a cell in the embryo sac that contains two haploid nuclei.

Double fertilization is a unique feature of angiosperms. It is a type of fertilization in which two sperm nuclei fertilize two different cells in the embryo sac. The first sperm nucleus fertilizes the egg to form the zygote. The second sperm nucleus fuses with the two nuclei in the central cell to form a triploid cell. This triploid cell will eventually develop into the endosperm, which is a food reserve for the developing embryo.

Answers

Answers:

High-energy electrons from NADH and FADH2, are passed into and along the electron transport chain .

The energy from the electrons moving down the chain is used to move H+ ions across the inner membrane .

H+ ions build up in the intermembrane space, making it positively charged and making the matrix negatively charged.

In the inner membrane, H+ ions move through channels of ATP synthase .

The ATP synthase uses the energy from the moving ions to combine ADP and phosphate, forming high-energy ATP .

A DNA microarray contains immobilized DNA that corresponds to different genes. The microarray is hybridized with fluorescently labeled DNA probes reverse transcribed from the control and experimental mRNA samples. The control probe is labeled with a red fluorochrome, while the experimental probe is labeled with a green fluorochrome. What will be the color of the spot representing a gene with moderately upregulated expression in the experimental sample relative to the control one

Answers

The color of the spot of a gene with moderately upregulated expression will be lime-green. A DNA microarray is a technique used to determine the expression level of many genes simultaneously.

A DNA microarray is a laboratory technique used to identify the genes that are being expressed in a cell.

A DNA microarray contains many tiny spots of specifically labeled cDNA samples referred to as probes, which can be hybridized by base complementarity to transcribed (mRNA) gene sequences.

In the DNA microarray, the probes can be fluorescently marked gene sequences.

After hybridization, the DNA microarray is then scanned in order to determine the level of gene expression of each mRNA that hybridizes with their corresponding probes on the slide.

In this case, green spots evidence genes that are being strongly expressed in the sample.

Please help me!! ASAP

Answers

Answer:

B) Mushroom --> Heterotroph

C) Algae --> Autotroph

A) Autotroph --> Producer

D) Hetrotroph --> Comsumer

Explanation:

Mushrooms are decomposers because like other fungi, they break down dead and decaying matter to make their own food

Producers, such as plants and algae, acquire nutrients from inorganic sources that are supplied primarily by decomposers whereas decomposers, mostly fungi and bacteria, acquire carbon from organic sources that are supplied primarily by producers.

Primary producer; organisms, such as plants and phytoplankton, that can produce their own food through photosynthesis or chemosynthesis; also called autotrophs.

Consumers are also referred to as heterotrophs in contrast to autotrophs, which are the producers of the food chain. Consumers therefore include animals and heterotrophic bacteria and fungi. Plants that are carnivorous and therefore consume organic matter as well are regarded as both consumers and producers.
