Explanation:
how would an animals color help it survive? give an example
Answer:
A lion hides in the tall dunes and yellowish collored grass which makes in invisible to other animals nad helps it get prey and not get attacked by hyenas.
Explanation:
Answer:
An animal's color could help it survive by blending into its surroundings so it is less visible to predators and prey.
Example: A polar bear's fur is white, and all the snow in Antartica is also white. Therfeore, it is hard for predators to find the polar bear and for prey to escape because they don't see the polar bear.

Bat wings, a human hand, and a whale flipper are all ________________structures. Explain WHY?
Butterfly wings and bat wings are examples of _______________ structures.
The mouths of horseflies and mosquitoes are examples of _______________ structures.
A _______________ structure is one that does not currently have a function in the organism. Give an example.
Comparing structures of embryos is an example of __________________.
If embryos share a common structure, what does that say about their evolutionary relationship?
How would the protein sequence of two closely related species compared to the protein sequences of two unrelated species? Give an example of each here.
Answers:
1.blank: Homologous
why?: They all have similar structures passed on from a common ancestor. Although they all have different functions now, they still all have the same basic pattern of bones.
2.blank: Analogous
why?: Butterflies and bats are both unrelated organisms but they both have similar structures. However, unlike homologous structures, analogous structures do the same job (help the organism fly) but are structured entirely differently because they evolved in the two species independently and did not share a common ancestor.
3.blank: Homologous
why?: (see question 1 ^)
4.blank: Vestigial
example: An example of a vestigial structure is a human's tail bone.
why?: Over time humans evolved and our tail bones shrank as we adapted. While we still have one, it serves no purpose in our lives today.
5.blank: Embryology
why?: Embryology is the branch of science and medicine that is focused on the development and study of embryos. Scientists in this field study the prenatal development of gametes, fertilization, and development of embryos and fetuses.
6.answer: They share a common ancestor
why?: Embryos of many different species can show evidence of sharing a common ancestor based on the similarities and structures of them all. Similar structures during development support common ancestry. For example, all vertebrae embryos develop gill slits and tails but not all develop into those structures. Over time as organisms evolved their structures changed with them.
7.answer: If the protein sequence of two species is closely related the two species are most likely similar, but the protein sequences of two unrelated species are not similar meaning these two species are very different. By comparing the positions of amino acids on protein chains you can determine how similar the species are. The less different the positions are, the more alike and related they are.
why?: For example, humans and chimpanzees only have one position on the amino acid chain where they are different but if you compare humans and moths there are 31 different positions.

How are meiosis and mitosis similar?
O A. They happen at the same time.
B. They both produce new cells.
C. They both produce sex cells.
D. They both produce diploids.
Answer:
Both creates new cells
Explanation:
Meiosis and mitosis both results in the production of new cells. Therefore, the correct statement is option B.
What is meiosis?Mitosis and meiosis result in cell division and the production of new cells. In mitosis, two genetically identical daughter cells are formed by a parent cell and are responsible for the asexual reproduction of organisms.
In meiosis, four daughter cells are formed from a single parent cell which is genetically diverse, and each daughter cell receives half the number of chromosomes present in the parent cell. Meiosis is the process by which gametes (sex cells) are produced in organisms, and it is responsible for the sexual reproduction of the organisms.
Therefore, both mitosis and meiosis result in the production of new cells. However, mitosis results in the production of two identical daughter cells, whereas meiosis results in the production of four genetically diverse daughter cells.

A cheetah, like those shown below at left, and a paramecium, like the one shown below at right, are both living things. According to the cell theory, what can you conclude about these two very different organisms?
The correct option for this question is as follows:
a) they are made of many cells
b) they are made of one or more cells
c) they come from the same kind of cell
d) they come from noncellular structures
Answer:
The correct answer is - option b. they are made of one or more cells
Explanation:
The cell theory has three major parts that are; the cell is the basic and physiological unit of the organism, all living organisms are made up of one or more cells, new cells come from the pre-existing cells.
On the basis of the cell theory, we can say that all organisms including the cheetah that is a multicellular organism or paramecium a single-celled organism, are made up of one or more cells.

Answer:
c
Explanation:
Magma and groundwater are responsible for the eruption of geyser.
GeyserGeyser eruptions are as a result of the conversion of thermal to kinetic energy during decompression.
When the groundwater deep in the ground is heated up by magma, pressure is released and the water will erupt out of the ground as a geyser. Eruptions occur about every 50-100 minutes.

Choose all the answers that apply. The atmosphere: is mostly made of nitrogen is weightless protects earth from harmful radiation contains water vapor is affected by events in the hydrosphere
Answer:
The atmosphere: is mostly made of nitrogen, protects the Earth from harmful radiation, and contains water vapor.
Explanation:
The atmosphere can be defined as the gassy wrapping covering a planet, in this case, the Earth.
The Earth´s atmosphere is composed of water vapor, N₂ (78.08%), O₂ (20.95%), Ar (0.93%), CO₂ (~0.03%), and Oz (0.01%). There are also other gases in reduced concentrations. Water vapor might reach 4% of the atmosphere near the Earth's surface. Water vapor and ozone absorb infrared radiation and are important in defining the terrestrial clime and keeping the environmental conditions needed for life. They protect the Earth from harmful radiation.
The atmosphere is composed of different layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The troposphere is the most inferior layer, in contact with the Earth´s surface, composing almost 90% of the atmospheric mass.

is mostly made of nitrogen, protects the Earth from harmful radiation, and contains water vapor
