Answer: Species can change over time in response to changes in environmental conditions through adaptation by natural selection acting over generations. ... Evolution results primarily from genetic variation of individuals in a species, competition for resources, and proliferation of organisms better able to survive and reproduce.

Describe the process of cloning from start to finish.
Answer:
1. Isolation of donor DNA fragment or gene.
2. Selection of suitable vector.
3. Incorporation of donor DNA fragment into the vector.
4. Transformation of recombinant vector into a suitable host cell.
5. Isolation of recombinant host cell.
Answer:
Explanation:
In standard molecular cloning experiments, the cloning of any DNA fragment essentially involves seven steps: (1) Choice of host organism and cloning vector, (2) Preparation of vector DNA, (3) Preparation of DNA to be cloned, (4) Creation of recombinant DNA, (5) Introduction of recombinant DNA into host organism, (6) ...A student looks at the daughter cells that result from a process of cell division. Which evidence would support that the process is meiosis? A. The daughter cells are larger than the parent cell B. The daughter cells are the same size as the parent cell C, the genetic material in the daughter cells is the same as in the parent cell D. The genetic material in the daughter cells is different than in the parent cell
Answer: C
Explanation: When daughter cells divide, they always pick up most of the genetic materials/features that the parent cell have.
what is xylem and phloem in science?
Answer:
The xylem is one of the two types of tissue transported from the vascular plants, the other being the phloem.
Answer:
Xylem and phloem Plants have tissues to transport water, nutrients and minerals. Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids between the leaves and other parts of the plant. Xylem and phloem in the center of the plant root

Justin wants to know how much gas his mother will save if he rides his bike to school rather than being driven in the car. For one month, Justin rides his bike to school. Every week, he asked his mother how much gas she put in the car. The next month, Justin had his mother drive him to school. Again, every week he asked her how much gas she put in the car. What could Justin do to improve this experiment?
Answer:
ask his mother?
Explanation:
Answer:
To improve the experiment, Justin should have created a hypothesis and could have repeated the experiment to see if the results were at least similar.

What is a pill bugs habitat
Answer:
The pillbug's main habitat is under mulch, fallen leaves, and rocks. Pillbugs are nocturnal and require humid conditions during the day. Pillbugs are generally found in soil with sowbugs, millipedes, and earthworms. Their preferred soil habitat is composed of organic matter and has a neutral to alkaline pH.
Leaves of a healthy potted plant were coated with Vaseline to block stomata. Will this plant remain healthy for long? State three reasons for your answer.
➜ If waxy coating is made on the surface of leaf, loss of water in the form of water vapour does not take place. Even the gaseous exchange will not take place. So, photosynthesis will either be reduced or will not take place.
The plant will not remain healthy for long because:
[i] Exchange of gases will not take place.
[ii] Photosynthesis will either be reduced or will not take place due to lack of CO2.
[iii] Transpiration will not take place, so there will be no mechanism of cooling in hot weather.

On the colorful map, in general, where is the youngest crust located?
Answer:
The youngest crust (shown in red) is near mid ocean ridges and spreading zones. All three rock types in the earth's crust—igneous, sedimentary, and metamorphic—can also be recycled back to their original molten magma form. This process occurs when oceanic crust is pushed back into the mantle at subduction zones.

how do scientists use rock layers to date fossils ? USE IN YOUR OWN WORDS.
40 POINTS DONT SKIP !
Answer:
By comparing a fossil to similar rocks and fossils of known ages, relative dating can be used to estimate its age. Absolute dating is a method of determining the precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil itself or, more commonly, the rocks that surround it.

A set of 23 chromosomes in a human cell
contains 3.2 billion pairs of DNA bases in
sequence. On average, about how many pairs
of bases are in each chromosome?
Explanation:
The human genome contains approximately 3 billion of these base pairs, which reside in the 23 pairs of chromosomes within the nucleus of all our cells. Each chromosome contains hundreds to thousands of genes, which carry the instructions for making proteins.The human genome contains approximately 3 billion of these base pairs, which reside in the 23 pairs of chromosomes within the nucleus of all our cells. Each chromosome contains hundreds to thousands of genes, which carry the instructions for making proteins.
What is chromosome ?
A chromosome is a thread-like structure present in the nucleus of cells such as plant, animal and human cells and it is made of a molecule of DNA (Deoxyribonucleic acid) and histone proteins.
It is composed of three components, DNA, proteins and RNA, amount of the DNA content ranges from 30 to 40 %, the amount of proteins from 50 to 65%, and small amount of RNA from 1 to 10%.
Two types of protein present in DNA such as histone and non-histones proteins, histone constitute large amount (90% of total protein), whereas non-histone is present in small amount (around 10% of total protein).
The histone protein is basic, whereas, the DNA is acidic, so it can be neutralized; DNA in chromosome is present in two forms such as Euchromatin and Heterochromatin.
