hydrogen and oxygen come pouring out. it drips and it dribbles and it comes from a spout
Answers
Answer:
Water
Explanation:
This looks like a proverbial question, so I'll try and answer it as best as I can
Th mixture of 'hydrogen and oxygen came pouring out' to give water. Water is a liquid that 'drips and dribbles and it comes poring from a spout'
The question is talking about the reaction between hydrogen and oxygen to give water; a form of liquid as the by-product.
The reaction involves one atom of oxygen reacting with two atoms of hydrogen with an hydrogen bonding in-between to give a molecule of water.
Also note that a spout is a stream of liquid issuing from somewhere with great force. So the answer is water.

If each person inherits two copies of any given gene from their parents, those who inherit two copies of the same gene variants are known as homozygous individuals. Those who inherit two different variants of the gene are known as heterozygous individuals. Determine the zygosity of samples 1, 2, and 3. DNA sample 1 DNA sample 2 DNA sample 3 Zygosity (homo/hetero) Allele contained (TNF1 and TNF 2)
Answers
Zygosity refers to the genetic composition of an individual with regards to a specific gene, indicating whether the individual is homozygous (inherits two identical copies of a gene) or heterozygous (inherits two different copies of a gene).
For the samples 1, 2, and 3, the zygosity can be determined based on the alleles contained in each sample. The alleles are variations of a gene and are indicated as TNF1 and TNF2.
If sample 1 contains two copies of TNF1, the individual is homozygous for TNF1. If sample 2 contains one copy each of TNF1 and TNF2, the individual is heterozygous for TNF. If sample 3 contains two copies of TNF2, the individual is homozygous for TNF2.
In summary, the zygosity of a sample is determined by the presence of different or identical copies of a gene. Homozygous individuals have two copies of the same gene variant, while heterozygous individuals have two different gene variants.

A farmer decides to test whether or not a fertilizer will make her crops grow bigger. In year 1, she plants corn in two different fields on her property and fertilizes one and not the other. She measures the height of 10 corn plants in meters from each field. She takes her measurements every week for three months. In year 2, she puts irrigation in one of the fields and conducts the same experiment.
Required:
a. What is the independent variable and the treatments (increments) used in the experiment?
b. What is the dependent variable and the units in which it was measured?
c. Name at least two controlled variables:
d. What is the hypothesis?
e. Identify two sources of error in the first year in the experiment:
f. Identify two sources of error in the second year in the experiment:
Answers
Answer:
a. independent variable: the fertilizer.
treatments: the use of fertilizer in one of the fields.
b. dependent variable: the crop growth in height.
units: meters
c. two controlled variables: soil pH / solar-radiation exposure, and water supply
d. hypothesis: the fertilizer makes the crops grow bigger.
e. two sources of error in the first year:
the researcher might plant the two crops under different conditionstake wrong measures of the height of the cornsf. two sources of error in the second year:
she can fail in irrigating the crops climatic and environmental conditions might change and have different consequences on each of the fields (this source affects the results influencing the growth of the plants).Explanation:
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. These changes allow analyzing its effects on the dependent variable. Usually, the independent variable is represented by the X letter. In the exposed example, the fertilizer is the independent variable. Treatments: Refers to the experimental procedure applied in the experimental group. In this example, the use of fertilizer is the treatment. Here the experimental group (the one that receives the experimental procedure, with changes in the independent variable) is the fertilized field. Data from the experimental group is compared with the data from the control group, to analyze the effects of the fertilizer.Dependent variable: The values of these variables respond to any change in the independent variable. It represents the quantity of something. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually identified by the letter Y. In the exposed example, the crop growth rate in height is the dependent variable, that depends on the fertilizer used in that field. The units in which the crop is measured are meters in height. Controlled variable: Refers to those variables equally applied to every group or subject in an experiment and have no influence on the results. These variables do not affect the change in the dependent variable values. In the exposed example, soil pH and solar-radiation exposure can be two controlled variables, as they must be equal for both fields. Water supply by irrigation ducts during the second year in both fields is also a controlled variable. Hypothesis: A hypothesis is a possible answer for a question, a speculation that is not verified yet and requires corroboration. A hypothesis must express what is expected to occur in a perfectly comprehensive manner. It must be objective and directly related to variables. In this example, the hypothesis might be that the fertilizer makes the crops grow bigger. Errors: These are the differences between the observed data or taken values and what is really happening in nature, which can lead to a misinterpretation of what is actually going on. These errors might be systematic mistakes performed by the researcher when measuring, taking data, applying the treatment, etc. Or they might be due to random errors, which are due to failures in the instrumentals, changes in the environment, a single mistake of the researcher while taking measures, among others. During the first year, the researcher might plant the two crops under different conditions (parcels with different slopes which affect solar-radiation) or might commit a mistake while applying the fertilizer (different concentrations for example), or might take wrong measures of the height of the corns. During the second year, she can fail in irrigating the crops correctly, providing more water to one of the fields. She can commit the same measuring mistakes. Or even climatic and environmental conditions might change and have different consequences on each of the fields.I need this now pleaseee

plant grows on the branches of a tall tree in a dense tropical forest. The plant is able to get better access to sunlight on the branches of the tree than it would on the forest floor. The plant takes up nutrients and water from the air, but not from the tree it grows on. What kind of relationship do the plant and tree have?
Answers
This commensalistic relationship demonstrates how organisms can exploit their environment and utilize other organisms to enhance their own survival and growth without causing harm or benefit to the host organism.
The plant and tree have a commensalistic relationship. In a commensalistic relationship, one organism benefits while the other is neither harmed nor benefited. In this case, the plant benefits from growing on the branches of the tall tree in the dense tropical forest because it gains better access to sunlight, which is essential for photosynthesis and growth. By growing on the tree's branches, the plant is able to reach higher above the forest floor where sunlight is often limited due to the dense canopy. This advantageous position allows the plant to thrive and maximize its chances of survival.
On the other hand, the tree is unaffected by the presence of the plant. It does not provide any resources to the plant, nor does it suffer any negative consequences from the plant's presence. The tree is simply used as a physical support structure for the plant, with no direct interaction or exchange of nutrients between them.

Answers
Meiosis is the process by which the reproductive cells are created. Those reproductive cells are called "gamete cells", in opposition to the other cells that are called "autosome cells". As it's goal is to promote reproduction, the gamete cells always have half of the number of chromosomes that would be found in autosome cells. This is important because two gamete cells must merge in order to ensure that reproduction takes place, and two gamete cells must become one autosome cell. So, gamete cells have an haploid number of chromosomes (n) and the autosome cells have a diploid number of chromosomes (2n, meaning the double of the amount of chromosomes in n).
Therefore, the correct answer is:
b) gamete cells and d) haploid number of chromosomes

Two major types of chemical substances that are broken down in chemical digestion are carbohydrates and proteins. Carbohydrates are broken down by the enzyme amylase, which is found in saliva and the pancreas.
Proteins are broken down by a group of enzymes called proteases, which are produced by the stomach and pancreas. Proteases break down proteins into smaller peptides and individual amino acids, which can be absorbed by the body and used to build new proteins or as a source of energy. Overall, the breakdown of carbohydrates and proteins in chemical digestion is crucial for the body to obtain the nutrients it needs for energy, growth, and repair. Amylase breaks down complex carbohydrates into simpler sugars, such as glucose and fructose, which can be absorbed by the body and used for energy or stored as glycogen in the liver and muscles.
