A farmer wants to know if adding antibiotics to cow feed will fatten them up. He takes two groups of 25 cows each. One group is given an antibiotic pill and the other group is given a placebo (empty pill). Both groups were fed the same food, given the same amount of water, and were provided with the same level of activity. They were weighed at the end of a month. Hypothesis: Independent Variable: Dependent Variable: Control Group: Experimental Group:

Answers

Answer 1

Answer:

The correct answer is-

Hypothesis: Antibiotics cause weight gain in cows.

Independent Variable: Antibiotic pill

Dependent Variable: Weight of cow

Control Group: a group of cows gets a placebo pill

Experimental Group: a group of cows gets an antibiotic pill

Explanation:

The Independent variable is the variable that causes the response from the dependent variable or affects the dependent variable in this study the antibiotic pill affects the weight of cows so The independent variable is an antibiotic pill and the dependent variable is the weight of cows.

The control group is the group of subjects that did not get the treatment in a scientific study in the case of this study group of cows that receives the placebo pill is the control group and the experiment group is subjects that receive the treatment which is a group with the antibiotic pill.

inject DNA or RNA into the nucleus of a cell to reproduce.

Answers

Answer:

The characteristic of injecting DNA or RNA into the nucleus of a (host) cell corresponds to viruses.

Explanation:

Viruses are not considered living beings, since they are only made up of genetic material covered by a viral capsid and cannot fulfill the functions of a cell. For this reason viruses need to introduce their genetic material into a host cell, to transcribe its genetic code and achieve replication.

Due to their mechanism of reproduction, viruses are biological agents capable of producing disease by altering the conditions of the organisms they use as hosts.

Which of the following inhibits the seepage of rainwater into ground
(a) Concrete floor (b) play ground (c) grass lawn (d) forest land

Answers

Answer:

What inhibits rainwater seepage into the ground is the concrete floor.

Explanation:

In general, water from rain is usually absorbed by the ground, due to its relative porosity. Concrete is solid and non-porous, forming an impermeable layer that prevents water from passing through it.

Concrete comes from a mixture of cement, sand and water, forming a malleable mass that hardens when dry. It is used for the manufacture of floors and buildings, and is characterized by its relative impermeability.

Other options are not correct because:

    Playground, grass lawn and forest land allow the absorption of water from rain.

The unit of genetic organization in all living organisms is the chromosome.
How does the function and structure of the chromosome differ in prokaryotes?

Answers

Answer:

The structure and function of the chromosome are different in both the prokaryotic chromosome and eukaryotic chromosome. They differ in their size as the genetic information they carry is different from one another.

Eukaryotic chromosome have a different shape from the prokaryotic chromosome as the bacterial chromosome is circular and less complex due to no histone found in prokaryotes as we see in the eukaryotic chromosome. SIze of the bacterial or prokaryotic chromosome is also small and not found in condensed form as these cells carry less genetic information than eukaryotic cells.

Answers

Answer:

biotic

Explanation:

because bio means life then forest fires must be biotic

Fire is non-living, and non-living elements are the abiotic elements in an ecosystem. Thus, fire is an abiotic element in an ecosystem, but rarely mentioned.

The forest ecosystem is made up not only of living organisms (trees, animals, plants, and other living things) but also of non-living organisms (soil, water, air, and landforms) that make up the forest ecosystem.

A forest ecosystem’s abiotic elements include oxygen-rich air, water present in several bodies of water, organic compounds in the trees and soil, and dead plant and animal remains.

Weathering, Erosion, and Deposition

Weathering is the process where things are broken down. (example rocks are weathered by the wind.)

Erosion is the process where the broken down materials are transported to another place. This can be by wind, water, etc.

Deposition is the process where the sediments are deposited at a new location.

Force and velocity are different because

Answers

Answer:

A force pushes or pulls on an object, but velocity is simply something an object has.

Explanation:

Force and velocity are different because force measures the power or strength through which an object with a specific mass accelerates in a particular direction while velocity measures the speed of a moving object in a specific direction.

What is a Force?

A force may be defined as a process of pushing or pulling on an object with mass that significantly causes it to alter its velocity. It is a vector quantity that has both magnitude and direction.

Velocity is characterized as the distance covered by an object in a unit of time. In a more simple sense, it is also defined as the displacement of the object in unit time. It is a vector measurement of the rate and direction of motion.

Therefore, force measures the power or strength through which an object with a specific mass accelerates in a particular direction while velocity measures the speed of a moving object in a specific direction.

What is atom?

The smallest component of ordinary stuff that makes up a chemical element is an atom. Atoms that are neutral or ionized make up every solid, liquid, gas, and form of plasma.

Atoms are incredibly tiny, measuring typically 100 picometers across. Due to quantum effects, they are so small that it is impossible to predict their behavior with sufficient accuracy using classical physics, as would be the case, for example, if they were tennis balls.

Each atom is made up of a nucleus and one or more electrons that are linked to it. One or more protons and a significant number of neutrons make up the nucleus.

The protons are positively charged, while the electrons are negatively charged.
