The evidence for continent drift theory is that places with hot climates once had glaciers. Therefore, option B is correct.
What is continental drift theory?According to the Theory of Continental Drift, the continents of the Earth move relative to one another and appear to be drifting over the ocean floor together.
Wegener constructed a ring around the south pole using the regions that had been ice-covered. The conclusion of the theory is, Over the past 300 million years, the continents have drifted to their present locations after having formerly been a single, bigger continent.
The fit of the continents, the distribution of prehistoric fossils, rocks, and mountain ranges, as well as the placements of prehistoric climatic zones, were all used as evidence for continental drift. Hence, option B is correct.

The statement that can be used to describe DNA methylation is "A mechanism involving attachment of methyl groups to certain bases for the long-term inactivation of genes during development."
Option D.) is correct.
Define DNA methylation.DNA methylation controls gene expression by attracting proteins implicated in gene repression or preventing transcription factor(s) from binding to DNA. The pattern of DNA methylation in the genome varies during development as a result of a dynamic process that includes both de novo DNA methylation and demethylation.
DNA methylation is an epigenetic mechanism that happens when a methyl group is added to DNA, altering the function of genes and influencing gene expression.
It's a process that involves attaching methyl groups to specific bases in order to inactivate genes for a lengthy time throughout development.
So, the statement that can be used to describe DNA methylation is option D.)

Which is a unicellular fungus?
A Slime mold
B Mushroom
C Yeast
D none of these
Explanation:
Unicellular fungi are generally referred to as yeasts. Saccharomyces cerevisiae (baker's yeast) and Candida species (the agents of thrush, a common fungal infection) are examples of unicellular fungi. Example of a unicellular fungus: Candida albicans is a yeast cell and the agent of candidiasis and thrush.
The wing of a bird and the front limb of a mammal have a similar number and arrangement of bones. Which evolutionary relationship explains these similarities? A. The wing and front limb are homologous structures; each evolved from a common ancestor. B. The wing and front limb are analogous structures; each evolved from a common ancestor. C. The wing and front limb are analogous structures; each evolved independently. D. The wing and front limb are vestigial structures; one evolved from the other.
Answer:
A
Explanation:
The correct answer would be that the wing and front limb are homologous structures; each evolved from a common ancestor.
Homologous structures are organs of different organisms that look similar in structure but perform different functions on their respective owners. They are as opposed to analogous organs which look different on different organisms but perform similar functions on them.
An example of the homologous organ is the wing of birds and the fore-limbs of mammals which are both built on a five-digit plant, also known as pentadactyl plan. While birds use their wings to fly, the fore-limbs of mammals are adapted for grasping or walking. An example of the analogous organ is the wing of birds and the wing of insects. They both look structurally different but are both for flying.
The correct option is A.

A.avoid recycling materials
B.eliminate all plant life on this planet
C.consider the impact of their actions
D.use as much energy as possible
C. Consider the impact of their actions, is the correct answer.
A is not correct because recycling helps protect the environment and helps boost the economy. B is not correct because plants helps supply oxygen for humans and animals.

What best describes a high pressure system? Question 4 options: Warm, rising air that creates cloudy, rainy weather Warm, rising air that creates clear, sunny weather. Cool, sinking air that creates cloudy, rainy weather Cool, sinking air that creates clear, sunny weather
Answer:
a high pressure system : Cool, sinking air, that creates clear, sunny weather.
Explanation:
The characteristics of the high-pressure system is marked by the presence of the cold and sunny days as compared to those of the warm and low-pressure pressure regions of the world. The air is light and lifts up easily and hence leading to the formation of clouds and rainfall. As compared to the cold air mass that is dense and hence has low moisture contents.Which of the following would be considered the strongest evidence that two species are related to one another?
a. common structures

Specialized cells are __________ intocells with specific functions
Specialized cells are stem cells that turn into cells with specific functions
Specialized cells are differentiate into cells with specific functions.
What is cell differentiation?Cells are the fundamental cornerstones of all life. Numerous numbers of cells construct the human body.
The process by which dividing cells alter their functional or phenotypical type is known as cell differentiation. All cells, it is assumed, derive from stem cells and acquire their functions as they mature.
In response to antigen exposure, some differentiation occurs. Differentiation alters a cell's size, shape, membrane potential, metabolic activity, and responsiveness to signals significantly.
These changes are primarily the result of highly controlled changes in gene expression and are the subject of epigenetic research.
Mesenchymal stem cells, epithelial stem cells, and muscle satellite cells are the three types of differentiated cells.
Thus, the answer is differentiation.

Metals and minerals accumulate in specific regions on Earth due to _______ activity and as part of the rock cycle. When sustainable yield is achieved, the rate of replenishment is equal to the rate at which the resource is harvested. This means that the resource can be harvested _______. Plate motion can create the proper temperature and _______ underground for hydrocarbons to release from kerogen.
Answer: volcanic
indefinitely
pressure
Explanation:
It should be noted that metals and minerals are regarded as non renewable resources which implies that they cannot be replenished.
They accumulate as a result of volcanic activities which takes place in the Earth. The resources can be harvested indefinitely when there is achievement of the sustainable yield. Plate motion can then create the proper temperature and pressure underground that is required for the hydrocarbons to release from kerogen.
Answer:
1. Non-renewable
2. Volcanic
3. Indefinitely
4. Pressure
5. Metals are found in rocks and can be moved by erosion and rainfall. these processes carry metal away from weathered rock, causing metals to accumulate in sediments, rivers, and streams.
