A student is collecting the gas released from a plant when exposed to sunlight. The gas being collected is:
A) water
B) Carbón dioxide
C) ATP
D) oxygen
Answer:
D
Explanation:
Plants absorb carbon dioxide and releases oxygen, that is part of the reason trees are important to the earth because one, many animals live in forests, and two, they give oxygen to the earth.
Describe the main molecule found in nucleus and explain how it controls the cells functioning
The main molecule found in nucleus is called DNA(deoxyribonucleic acid). This molecule is made of subunits called nucleotides. A nucleotide is made of a nitrogenous base that can be adenine, thymine, guanine or cytosine; a five carbon sugar called deoxyribose and a phosphate group. This molecule controns protein synthesis. Proteins are crucial to the cell's function.

How do police use DNA to try and solve crimes? Do you think city police departments should make their own DNA databases? Explain why or why not. Back up your answer with facts and details from the Article.
Answer:
Police matches the DNA with the criminal present in their database.
Explanation:
Police use DNA that are collected at the site of crime in order to solve crimes because the criminals DNA are mostly found at the site of crime. the police collected these DNA and search in their database where the DNA of all the criminals are present. if the DNA matches with the criminal present at the database so it means that this criminal commit this crime so it is arrested and further investigation will be held. Yes, city police departments should make their own DNA databases in order to solve the case quickly.

What is the probability of producing a roan (red and white) cow when a white cow is crossed with a red cow?
Cross: RR x WW
Answer:
A cross between a roan bull (Ww) and a white cow (ww) produces roan and white phenotypes in a 1:1 ratio.
Explanation:
Two alleles are influencing the color of the hair of the cow-W red and w white.
These alleles show that a hybrid Ww has red hair. The genotype of the bull is Ww, WW is red and ww is white. So, mixing the red and white cows is 1:1.
Wheat has flowers similar to those in Fig. 5.1, but reproduces by self-pollination. Explain the consequences of self-pollination for a population of plants.
Answer:
The transfer of mature pollen grain from anther of the flower to the stigma of the same flower of the same [species is called self pollination.
Generally, the transfer of pollen grains by wind,animals,and water to stigmas is called pollination. It is a means of vegetative propagation which ensures reproduction.
Therefore during self pollination, the same genes are distributed from one generation to another. Thus genetic purity is ensured. It also ensured reproductive success. because there is little chance of the pollen grain getting lost in transit. It is also certain a particular plant would always breed true.
Additionally it prevent the process of transfer of genes in some transgenic crops( rice, maize) where through genetic engineering some genes are introduced in their genome.
The only negative effect is lack of genetic diversity. Therefore after a period of time the plants get weak and prone to diseases and infection. Because of poor resistant from lack of variation.

Three stages of development from an embryo from a fish salamander turtle and chicken . What information about evolutionary relationships can be inherited from the drawings
Answer:
Zygote, cleavage and hatching are embryogenic stages of fish, salamander, turtle and chicken.
Explanation:
The main embryogenic development stages of fish, salamander, turtle and chicken were zygote, cleavage and hatching. all these stages are present in these organisms which shows that fish, salamander, turtle and chicken are evolved from a single ancestor. Due to similar embryogenic development stages indicates close evolutionary relationships among these organisms.

Compare the carrying power of a small, mountain stream in the mountains with that of a slow large river that is about to enter the sea.
(Note: Needs to be detailed) [this is more of a Geology question]
Answer:
The carrying power of a small, mountain stream in the mountains with that of a slow large river that is about to enter the sea is explained below in details.
Explanation:
A mountain stream is a river or stream, normally with a sheer slope, running down a mountainside. Stream velocity is most noted in midstream near the exterior and is crawling along the stream bottom and shores due to friction.
The river stalls down at the entrance, so it doesn't have the energy to carry all the sand, dirt, and clay anymore. These deposits create the flat, regularly triangle-shaped tract of a delta.

How is sexual reproduction (meiosis) involved in cystic fibrosis? How is asexual reproduction (mitosis) involved in cystic fibrosis?
Meiosis is the cell division that enables sexual reproduction. It consists of two successive cell divisions, after which four genetically different cells are obtained, which contain half the number of chromosomes as the mother.
In 1-3 sentences, explain the structure and function of an enzyme.
Answer: Enzymes are life’s great facilitators. They create the conditions needed for biochemical reactions to happen fast. The general name that chemists use for chemical entity that increases the speed of a reaction is “catalyst.” Enzymes are biological catalysts they catalyze the chemical reactions that is happen inside living things.

Describe the nitrogen cycle. How do organisms obtain nitrogen? (minimum 5 sentences) ILL GIVE BRAINLIEST
Answer: Plants, from their roots, suck up nitrogen compounds. These compounds are obtained by animals as they consume plants. The nitrogen compounds in the organic matter re-enter the soil when plants and animals die or when animals excrete waste, where they are broken down by microorganisms, called decomposers.
Allows the cell membrane to engulf large molecules.
Diffusion

In an experimental study, the barnacle species Balanus was removed from rocks exposed at low tide. The barnacle species Chthamalus then established in the habitat where Balanus previously thrived. This provides evidence that:
Explanation:
There are two kinds of niches demonstrated by two barnacle species Balanus and Chthamalus where Balanus is being realized niche as it
is the actual habitat and this species interest with other species and other aspect affects the survival like competition and predation etc. Fundamental niche is demonstrated by Chthamalus as they can easily live and thrive in thehabitat and can multiply too and it will be still greater as opposed to realized.The right answer is, 'Chthamalus's basic niche is greater than its niche'
An ecosystem usually contains a single kind of habitat.

Explanation:
Decomposition is the process by which:
Carbon atoms are released into the soil
Carbon is converted to CO2
Organisms obtain energy by breaking down glucose
Answer:
Decomposition is the process by which carbon atoms are released into the soil.
Explanation:
Organic decomposition involves the process of degradation of a living organism by releasing its elemental components.
In the process of decomposition, chemical elements such as carbon are released mainly in the soil, contributing to its enrichment and use by other living beings.
The release of carbon —product of decomposition— to the soil, for recycling, is part of the carbon cycle.
The other options are not correct because:
The conversion of carbon into CO₂ is combustion. Organisms obtain energy by breaking down glucose is part of cellular respiration.Explain digestion Process.
Answer:
Each bite passes through several "cells" within the digestive system, and each of them has a specific function in terms of processing uneaten food.
Explanation:
The food begins to be processed in the mouth and prepared for the upcoming digestion process.
Saliva is important for food processing, among other things because it contains the enzyme ptyalin (alpha-amylase), which is responsible for the breakdown of starch and glycogen and continues its activities in the stomach.
Well-chewed food passes through the pharynx to the esophagus. During the swallowing of food, the opening of the trachea is closed, although it is possible that some crumb of food strays and causes a strong cough, which expels the excess from the trachea.
From the esophagus, food comes into the stomach, which is surrounded by ribs. Stomach acid is extremely strong and enables the conversion of food into liquid, which facilitates the further process of digestion.
Food from the stomach continues its way through the digestive tract to the duodenum, from the duodenum it reaches the small intestine.
Food processing in the large intestine is the last phase of digestion of food in the digestive tract. When the waste materials reach it, they need up to 24 hours to pass through the large intestine and reach the other end.
