The front legs of a cat and the arms of a human share a bone structure that suggests a common evolutionary lineage. Therefore, these skeletal structures are
Answer:
homologous
Explanation:
Since the front legs of a cat and the arms of a human share a bone structure that suggests a common lineage, these structures are said to be homologous.
Homologous organs are organs that share some similarities in different organisms but whose function differ in these organisms.
The organs are structurally similar but functionally different. Homologous organs represent one of the evidences scientists use to support evolution.
The front legs of cats and the arms of humans are functionally different, even though their structure is based on the same five digit plan.
why are metamorphic rocks denser then igneous rocks
Answer:
Metamorphic rocks are denser than igneous rocks, because of the way they are formed. To explain:
Metamorphic rocks are formed when all types of rocks are compressed under high temperature and pressure. Having been compressed under high pressure, they become denser.
Igneous rocks, however are formed when magma freezes. It could just freeze when it reaches a slightly colder area and is not affected by the pressure at all. Or if it was, it wouldn't be igneous anymore.

The Seven Sisters, seven stars located more than 400 light-years away in the Taurus constellation can be seen here with Venus and another constellation, Orion. The seven stars stay grouped together but seem to move, like the planet Venus. Why do stars seem to move like planets in the night sky?
A)Both the stars and the planets are orbiting around the Earth.
B)The night sky rotates around the planets in our solar system.
C)They seem to move because they are so far away and we cannot see exactly what happens.
D)Stars seem to move because Earth is rotating on its axis; planets do move around the Sun.
Answer:
D)
Explanation:
The main reason as to why stars seem to move like planets in the night sky is because of our Earth. The Earth is rotating on it's axis as well as revolving around the sun at the same time. Therefore turning once around us every 24 hours, which to us makes it seem as though the starts are moving like the rest of our planets do around the sun.
Answer:
The correct answer is D
Explanation:
Just like the starts other astronomical bodies such as the Sun, Moon, and planets look like they are moving from one point in the sky to another.
The simple explanation for this is because because of the the Earth is rotating on its axis. One can achieve same effect by trying to trun round standing at a point. It would appear that the environment is shifting however we are actually the ones doing so.

What are greenhouse gases
and how do they contribute
to global warming?
Answer:
they contribute to global warming because the greenhouse gases affect the ozone layer making it having holes which allow more sunlight to reach Earth surface which results to global warming
Explanation:
they contribute to global warming because the greenhouse gases affect the ozone layer making it having holes which allow more sunlight to reach Earth surface which results to global warming
Answer:
"Greenhouse effect" is the warming of the climate that results when the atmosphere traps heat radiation from Earth towards space. Certain gases in the atmosphere resemble glass in a greenhouse, allowing sunlight to pass into the "greenhouse," but block Earth's heat from escaping into space. These gases that contribute to the greenhouse effect include water vapor, carbon dioxide (CO2), methane, nitrous oxides, and chlorofluorocarbons (CFCs). Carbon dioxide is responsible for 53% of the of global warming. It is the result of processes of the use of products such as fuel deforestation and production of cement and other materials. Its permanence in the atmosphere varies, but it’s very high at all times since 80% lasts for 200 years and the other 20% can take up to 30,000 years to disappear. Methane is the next of the greenhouse gases which has the biggest effect on global warming with 15%. This is produced by activities such as livestock production, agriculture, sewage treatment, natural gas and oil distribution., coal mining, fuel use and is also given off from waste tips, and lasts an average of 12 years in the atmosphere.

How do substances like CO2 and water move in and out of the cell?
(Please Answer) :)
｡☆✼★ ━━━━━━━━━━━━━━ ☾
There are three processes you need to know of:
Diffusion, Osmosis and Active Transport.
Liquids (such as water) move via osmosis.
Osmosis is literally the movement of particles across a partially permeable membrane from an area of high conc to an area of low conc.
CO2 would move via either diffusion or active transport.
Diffusion is the movement of particles across the concentration gradient (i.e from high conc to low conc)
Active transport is the movement of particles against the conc gradient (i.e from low conc to high conc)

Answer:
1. Transcription, Nucleus
2. Translation, Ribosome (Cytoplasm)
Explanation:
All living organisms contains genetic material in their nucleus (for eukaryotes), usually in the form of DNA. The DNA stores the information that encodes the synthesis of useful products (proteins). However, the encoded information needs to be expressed, which is done in two major stages namely: transcription and translation.
Transcription is the first process of gene expression which occurs in the NUCLEUS of eukaryotic cells, since the DNA is located there. Transcription involves the synthesis of a RNA molecule from a DNA template i.e. the information in the DNA is used to produce a RNA.
Translation is the second process of gene expression. In eukaryotes, the RNA transcript moves out the nucleus into the cytoplasm of the cell, where organnelles called RIBOSOME attach to it. In the ribosome, the RNA is used to synthesize amino acid sequence, which eventually becomes a PROTEIN. Hence, the information contained in the RNA molecule is translated into a protein molecule.

How would you study ecological succession in different ecosystems?
Answer:
Ecological succession in different ecosystems can be studied by first of all recognizing the various ecosystems and what makes them unique. Thereafter, sample collection methods and regimen must be established with standardized experiments for establishing diversity of organisms in the ecosystem. Regular data storage and interpretation is needed to know what goes on in the ecosystem and at what time.
Explanation:
To study ecological succession in a fermented food sample, for example, palm-wine, methods such as metagenomics can be used to determine the diversity of organisms at various points from the tapping stage through various hours of alcoholic fermentation. This will reveal the initial colonizers of the sample and what happens to them as the pH of the palm-wine changes. Eventually, only organisms that can tolerate high acidity will thrive as the fermentation proceeds.
Which is true for both photosynthesis and cellular respiration? A. They require oxygen as a reactant. B. They require organelles. C. They require light energy from the Sun. D. They require cells to use water.
Answer:
B
Explanation:
Photosynthesis and cellular respiration are opposite processes, so a reactant of one would be the product of the other and vice versa. This means that A, C, and D are false because they don't apply to both processes. B is true because photosynthesis requires chloroplasts and cellular respiration requires mitochondria to occur.

Predict the most likely effect of a two-nucleotide deletion in the middle of the intron located between exons 4 and 5 on the structure of protein A. Justify your prediction.
Will mark brainliest!
Answer:
The question is incomplete; however, it is important to note that the deletion of two nucleotides in an intron generally doesn't have effect on gene function, thereby they are generally neutral.
Explanation:
Introns are gene regions that were historically considered as junk DNA because they do not encode for proteins, and therefore they were thought to have no biological function. However, in the last years, it has been discovered that introns are gene regions that encode non-coding RNA (ncRNAs), which are involved in gene regulation.

What is a chloroplast?A chloroplast is a type of membrane-bound organelle known as a plastid that conducts photosynthesis predominantly in plant and algal cells.
Chloroplasts provide energy through photosynthesis and oxygen-release mechanisms, which support plant growth and crop yield. As such, chloroplasts are responsible for the manufacture of active substances such as amino acids, phytohormones, nucleotides, vitamins, lipids, and secondary metabolites
Chloroplasts are oval-shaped and have two membranes: an outer membrane and an inner membrane. Between the outer and inner membrane is the intermembrane gap roughly 10-20 nm wide. The space within the inner membrane is the stroma, the dense fluid within the chloroplast.
