Answer:

A. A thick, waxy covering to prevent evaporation.

Explanation:

Because the desert is usually dry and hot, plant that live in these ecosystems need to adapt to the environment to prevent the loss of water. Water escapes from plants through their leaves as a result of photosynthesis. Desert plants have special adaptations to at least reduce the loss of water and one of them is the thick waxy covering of the leaves to seal in the water.

Katyanochek1 [597]

Answer:

The correct answer is option C. "2+".

Explanation:

A common procedure to test for the presence of antigens is to perform an agglutination reaction by performing an antibody screen. In an agglutination reaction that is graded  2+ the red blood cells start to be broken and medium-sized agglutinates are formed. In this reaction no red blood cells are free, only agglutinates are seen at the bottom of the microtubes. The characteristics of the reaction herein described concur with an agglutination reaction that is graded  2+.

What happens when lakes are acidified?
Dima020 [189]
Lakes that have been acidified cannot support the same variety of life as healthy lakes. As a lake becomes more acidic, crayfish and clam populations are the first to disappear, then various types of fish. Many types of plankton-minute organisms that form the basis of the lake's food chain-are also affected. As fish stocks dwindle, so do populations of loons and other water birds that feed on them. The lakes, however, do not become totally dead. Some life forms actually benefit from the increased acidity. Lake-bottom plants and mosses, for instance, thrive in acid lakes. So do blackfly larvae.

1. Key Concept List the
Ipatiy [6.2K]
<h2>DNA </h2>

Explanation:    

1) Experiment done by Griffith:

  • Griffith used two related strains of bacteria, known as R and S
  • R bacteria were nonvirulent, meaning that they did not cause sickness when injected into a mouse whereas mice injected with live S bacteria developed pneumonia and died
  • Griffith tried injecting mice with heat-killed S bacteria (that is, S bacteria that had been heated to high temperatures, causing the cells to die), the heat-killed S bacteria did not cause disease in mice
  • When harmless R bacteria were combined with harmless heat-killed S bacteria and injected into a mouse, not only did the mouse developed disease and died, but when Griffith took a blood sample from the dead mouse, he found that it contained living S bacteria
  • Griffith concluded that the R-strain bacteria must have taken up what he called a transforming principle from the heat-killed S bacteria, which allowed them to transform into smooth-coated bacteria and become virulent

2) Experiment done by Avery:

  • Avery, McCarty and MacLeod set out to identify Griffith's transforming principle
  • They began with large cultures of heat-killed S cells and, through a long series of biochemical steps progressively purified the transforming principle by washing away, separating out, or enzymatically destroying the other cellular components
  • These results all pointed to DNA as the likely transforming principle but Avery was cautious in interpreting his results
  • He realized that it was still possible that some contaminating substance present in small amounts, not DNA, was the actual transforming principle

3) Experiment done by Hershey and Chase:

  • Hershey and Chase studied bacteriophage, or viruses that attack bacteria
  • The phages they used were simple particles composed of protein and DNA, with the outer structures made of protein and the inner core consisting of DNA
  • Hershey and Chase concluded that DNA, not protein, was injected into host cells and made up the genetic material of the phage

Part of an important cellular process involving a DNA strand is modeled below. What is the purpose of this cellular process ?​
Burka [1]

Answer:

The correct answer is - Transcribing information in the DNA sequence for use by the cell.

Explanation:

The transcription process is the process that involves copying the sequence of DNA, that sequence is the information or code for the particular protein, to make RNA molecule that brings the information to the ribosome where translation process initiated to produce amino acid chain.

In the given diagram, the cellular process is showing is transcription as there is transcribing the sequence is shown which copy the sequence that is used for the cell and a useful part of protein synthesis
