What are chromosomes? When do chromosomes form?
Answer:
Chromosomes are coiled structures made of DNA and proteins. They contain genes, which basically code for proteins. Chromosomes form after DNA replicates. In other words, chromosomes form as DNA becomes foiled during the process of prophase I, thus creating chromosomes.

Which statements describe hormones in plants? Check all that apply.
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Hormones help buds form and grow in the winter.
Auxin is the only hormone involved in plant development.
(i know that the first 4 are not right and neither are A, B, and D (1, 2, 4)
Answer:
The correct statements are: 1, 2, and 3.
Cutting stems can stimulate hormones to start lateral leaf growth.
Some tropisms are controlled by hormones.
Cells grow faster in areas where auxin is concentrated.
Explanation:
Plant hormones such as Auxins perform various roles and helps in the growth and development of the plants. Cutting the main stem of the plant stimulates the auxin hormone and which stimulates the lateral elongation growth of the leaf growth.
Some tropisms are controlled by the hormones such as phototropism by auxin as a high concentration area of the auxin causes cell growth in a particular area and the concentration of auxin is stimulated by light.

Why can enzymes be used over and over again
Answer:
Enzymes are biological catalysts. They catalyse biochemical reactions. They increase the rate of reaction. They do not chemically react or get utilised in the reaction so enzymes can be used over and over again.
The DNA strand and pre-mRNA strand are anti-parallel. With this in mind label the 3' and
5' ends of the pre-mRNA strand in Model 1. Where would i put it??
Answer:
I think the right side is 3 prime and left sde is 5 prime
Explanation:
Because the process of transcription takes place in nucleus so it should be put inside the nucleus.
What is nucleus?In genomics, a nucleus is a membrane-enclosed organelle within a cell that houses the chromosomes.
What is Transcription?The process in which information of a strand of DNA is copied into a new m RNA molecule is known as Transcription.
The enzyme responsible for transcription is RNA polymerase. Transcription start when RNA polymerase binds to a promoter region at the start of a gene directly or through helper proteins. Initiation, Elongation, and termination are the three steps of transcription. Transcription is carried out with the help of enzyme RNA polymerase and some proteins known as transcription factors. Enhancer and promoter sequences are the DNA sequences on which transcription factors attach to initiate the transcription process by directing RNA polymerase to the correct transcription site.The transcription initiation complex is made up of transcription factors and RNA polymerase working together.

Fossils in _______ layers of rock are generally estimated to be _______ than fossils found in the deeper layers. (3 points)
older, younger
newer, younger
older, older
newer, older
Answer:
Answer number 2
Explanation:
So in Geology, Precipitation of rock layers took place over the last hundreds of millions of years...During that process many living organisms have died and are precipitated with the rock layers... Let me explain with an example.
Dinasours went extinct Million years ago while the Dodo bird went extinct a couple of hundred years ago
Would you expect to find Dinasour fossils in newer rock layers or the dodo? lets's say 200m deep? Dodo for sure, Dinasour fossils are waay too old to be found at such shallow deeps that's why fossils in newer layer of rocks are absolutely younger than fossils found at deeper layers

Answer:
D.Para la mayoría de los ecosistemas la energía proviene de la luz
Explanation:
Los ecosistemas requieren de un suministro constante de energía para poder sustentar la vida. A excepción de ecosistemas basados en fuentes hidrotermales, en general este aporte energético proviene del sol que suministra energía lumínica la cual es convertida por los organismos productores (por ej., plantas y algas) en compuestos orgánicos. Los productores representan la fuente de energía y alimento de consumidores primarios (por ejemplo, herbívoros), los cuales a su vez sirven de sustento para consumidores secundarios (por ej., carnívoros), estos suministran de alimento a los consumidores terciarios y así sucesivamente. Finalmente, los descomponedores son aquellos microorganismos que se alimentan de los restos orgánicos obtenidos a partir de productores y consumidores.

which two adaptations of herbivorous enables them to digest cellulose
Answer:
Cellulose Digestion in Herbivores
By means of the symbiotic gut bacteria, cellulose can be digested by herbivores with the help of monogastric digestion. Herbivores are less efficient than ruminants in the case of extracting energy from the digestion of cellulose. Here, cellulose is digested by microbial fermentation.
Explanation:
Their molar and premolar teeth help to crush and grind the food and bacteria present in their caecum help in the digestion of cellulose.
How does herbivorous digest cellulose?Cellulose is a polysaccharide made up of repeating glucose units linked by β-1,4-glycosidic bonds, only herbivores are able to digest this biomolecule.
Herbivores have molar and premolar teeth, this flat molars (back teeth) with rough surfaces, which are used for chewing up tough plant tissues. Ruminants have rumen having bacteria which are enabled animals to digest cellulose.
Inside the rumen of cattle, certain bacteria and protozoans are able to secrete the enzymes, which break the cellulose and convert it into glucose units to provide energy.
Therefore, teeth and bacteria two adaptations of herbivorous enable them to digest cellulose.

what process is responsible for the absence of glucose and amino acids in urine
Answer:
The force of hydrostatic pressure in the glomerulus (the force of pressure exerted from the pressure of the blood vessel itself) is the driving force that pushes filtrate out of the capillaries and into the slits in the nephron
Selective reabsorption can be considered the process responsible for the absence of glucose and amino acids in urine.
What is selective reabsorption?The selective reabsorption mechanism allows the absorption of different substances including glucose and amino acids in the urine.
This reabsorption occurs after filtration in the capillaries of the urinary system. The filtration and excretion of waste substances are associated with the formation of urea.In conclusion, selective reabsorption can be considered the process responsible for the absence of glucose and amino acids in urine.

explain the circulation of blood
Explanation:
blood comes into the right atruim from the body
Answer:
The circulation of blood is where basically the blood comes or goes into the right atrium from the body, this then moves into the right ventricle and is then pushed into what is called the pulmonary arteries in the lungs of a human. Once it has picked up oxygen, the blood will then travel back to the heart through the pulmonary veins, but this time it will go into the left atrium, so to the left ventricle and including out to the human body's tissues through the aorta.

The most important function of the endoplasmic reticulum is intracellular transport within the cell but ER also performs other functions.
What is intracellular transport?The Endoplasmic Reticulum transports nutrients from one part of the cell to the other within the cell.
What is Endoplasmic reticulum?The endoplasmic reticulum (ER) is a continuous membrane structure in eukaryotic cells that forms a series of flattened sacs inside the cytoplasm.
There are two forms of ER that are commonly found:-Rough ER, which has ribosomes embedded within its structure, giving it a rough appearanceSmooth ER, which lacks these ribosomes and hence appears smooth.The endoplasmic reticulum (ER) plays an essential role in protein synthesis, folding, modification, and intracellular transport.

a prey population consists of individuals with a variety of running speeds. The adaption that allows some of these animals to run fast would be an example of natural selection if it helps them
Answer:
Yes.
Explanation:
Yes, the adaption that allows some of these animals to run fast will be cause of natural selection because this fast running helps them to survive and save itself from predators. The organisms adapt certain features and characteristics in order to survive in that harsh environment that leads to natural selection. Natural selection occurs by selecting the best suited organism that can survive in that specific environment so this fast speed allows the organism to survive in their environment.
