dry lab evidence of evolution
Answer:no
Explanation: because it’s no
Answer:
The evidence for evolution
In this article, we'll examine the evidence for evolution on both macro and micro scales.
First, we'll look at several types of evidence (including physical and molecular features, geographical information, and fossils) that provide evidence for, and can allow us to reconstruct, macroevolutionary events.
At the end of the article, we'll finish by seeing how microevolution can be directly observed, as in the emergence of pesticide-resistant insects.
How is an
anatomical
adaptation
defined?
A. a system present within the
organism that allows it to perform a
biochemical reaction
B. a feature of the organism's body
that helps it survive and reproduce
C. a response from the organism that
changes it's behavior to help it survive
and reproduce
Anatomical adaptations involve every change in the organism's external structure. Option B. A feature of the organism's body that helps it survive and reproduce.
What is an anatomical adaptation?Anatomical adaptations are changes in the external structure of the organisms that help them survive and reproduce in a certain environment.
These adaptations allow the organisms
to camouflage if necessary (to scape from a predator or to hunt their prey, for instance), to protect themselves by imitating dangerous species' colors and shapes, to develop special structures needed to feed and move in that specific environment.
There are other two types of adaptations apart from anatomical ones. These are physiological and behavioral adaptations.
Options
A. a system present within the organism that allows it to perform a biochemical reaction ⇒ This is a physiological adaptation
B. a feature of the organism's body that helps it survive and reproduce ⇒ This is an anatomical adaptation
C. a response from the organism that changes it's behavior to help it survive and reproduce ⇒ This is a behavioral adaptation
The correct option is B. a feature of the organism's body that helps it survive and reproduce

Which action has a positive effect on air resources?
using fossil fuels
building new homes
walking to work or school
removing vegetation such as trees
Answer:
Person above me or below me is correct :)
Explanation:
The answer is C !!
- Have a good summer :)
Utilising fossil fuels has a detrimental impact on air quality because they produce dangerous pollutants like carbon dioxide and nitrogen oxides when they are burned.
What are the contaminants linking to the air pollution ?These contaminants are linked to higher air pollution levels, which can lead to a variety of health problems, such as heart disease and respiratory disorders. The effects of new house construction on air resources are complex.
On the one hand, since burning fossil fuels for energy and releasing building materials can result in the emission of hazardous chemicals, construction may increase air pollution. On the other side, if new homes are constructed in places with fewer air pollution, as in rural regions, they may result in better air quality.
A benefit of walking to work or school an advantage for air resources. Walking does not emit any pollutants into the air, making it a zero-emission mode of transportation.
Additionally, walking lessens traffic on the roadways, which can lessen vehicle-related air pollution. Air resources may suffer if trees or other vegetation are removed. By providing shade, trees not only assist to filter airborne pollutants, but they also help to chill the air. Because air pollutants are not being filtered out as well when trees are cut down, this might result in higher air pollution levels.

some chains of carbon atoms bend when the carbon atoms:
A. form single covalent bonds.
B. form double covalent bonds.
C. form bonds with oxygen atoms.
D. form bonds with hydrogen atoms.
Answer:
Fats with at least one double bond between carbon atoms are unsaturated fats. When some of these bonds are in the cis configuration, the resulting bend in the carbon backbone of the chain means that triglyceride molecules cannot pack tightly, so they remain liquid (oil) at room temperature.
What is one reason water can remain in the liquid state on Earth?
A. Earth's atmosphere is deep enough to allow water to cycle through
its solid, gas, and liquid states.
OB. Earth's surface is continually bombarded by comets, which add
liquid water.
OC. Earth's distance from the sun keeps the temperature just right for
liquid water to exist.
OD. Earth's atmosphere is warm enough to prevent water vapor from
condensing.

Answer:
c
Explanation:
water boils at 100 degrees Celcius and freezes at zero degrees Celcius. if you want to keep water in a liquid phase, the temperature has to be between 0 and 100 therefore earth is the only planet that is able to keep water in a liquid phase as it is not too hot nor too cold

The vascular tissues identify as:

b. xylem
What are Vascular tissues?Vascular tissues in plants are specialised tissues which transport nutrients and water through the plant. They are made up of two distinct kinds of tissues: xylem and phloem.
Xylem is in charge of carrying water and minerals that are dissolved from the plant's roots to its leaves. It is made up of many cell types, such as tracheids, vessel components, and fibres. Tracheids and vessel elements are long, hollow structures that create lengthy tubes when stacked end to end.
Sugars and other organic compounds are transported from the leaves to the remainder of the plant by phloem. There are two sorts of cells in it: sieve tube elements and cell companions. Sieve tube components are long, narrow cells that run end to end.
Therefore, the vascular tissues identify as:
a. phloem
b. xylem

A student carried out an experiment to model the digestion of starch by the enzyme amylase in the small intestine.
Visking tubing is a selectively permeable membrane that has small holes in it to allow small molecules to pass through. At regular intervals, the student tested the liquid inside and outside the Visking tube.
How could the student test for the presence of starch inside the Visking tubing?
Answer:
Put one drop on the dimple tile, and the rest in a test tube. Then put the teat pipette back in the water outside the Visking tubing. Test the drops of liquid in the dimple tile by adding one drop of iodine solution from the dropper bottle. If they turn blue-black, the liquid contains starch.

Question 2 options:
The forest cannot recover without human intervention
Primary Succession
Secondary Succession
Adaptive Radiation
Secondary Succession will occur after a fire burns down 100 acres of a forest. thus option C is correct.
What is secondary succession?When a disturbance does not completely remove all life and nutrients from the environment, secondary succession occurs.
Despite the fact that fire, flooding, and other disturbances can devastate a landscape, drive away many plants and animals, and reset the biological community to an earlier stage, the habitat remains alive because the soil stores nutrients and seeds that were laid down before to the disturbance.
Buried seeds can sprout soon after the disruption has passed, and some may have a better chance because of less competition and less shading. Some animals may have evolved to deal with a particular disturbance on a regular basis.

No. A law is something that happens without fail every time when being tested, or when it happens in nature. A law does not attempt to explain why the thing occurs, it only states it. A scientific theory is not something that can be tested on and will receive the exact same outcome each time. A theory attempts to explain an action seen in nature.
