5.2. Suggest how ecologists used the data in the graphs to calculate the total volume
of water used by a tree in 24 hours.
Answer:
When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others. These individuals will be more likely to survive and pass on their traits to their offspring. Over many generations, these favorable adaptations build up in a population. This may lead to speciation, which is the development of a new species.When a long-term environmental change occurs, certain individuals in a population will be better adapted for the new environment than others.

Answer:
The correct answer is -
1. Blending - C
2. Straining - D
3. Detergents - B
4. Meat tenderizer (protein enzymes) - E
5. Alcohol - A
Explanation:
To extract protein from various parts of the organisms there is a scientific process that helps in successfully extract it. Organisms such as plants have a rigid cell wall that is required to be broken in order to follow the scientific process of extracting DNA and protein.
Blending use to break the cell wall of the plants such as pea cells. After breaking the cell wall one needs to dissolve the cell membrane made up of lipids with the help of soap or detergents. After the dissolving cell membrane, there is a chance to DNA gets damaged by various chemicals, therefore, alcohol is used to allow DNA to form clumps or precipitate.
Straining is used to separate the cell organelle, dissolved cell membrane from DNA and protein. Papain is a meat tenderizer and a protein enzyme that cuts or breaks the protein.

At least two parallel channels of communication flow through each lateral geniculate nucleus. One runs through the parvocellular layers and a second runs through the magnocellular layers.
What are parvocellular and magnocellular layers?Parvocellular cells, also called P-cells, are neurons located within the parvocellular layers of the lateral geniculate nucleus (LGN) of the thalamus.
Moreover, magnocellular cells make up the magnocellular layers of the lateral geniculate nucleus. They are relatively large cells that display specialization in detecting aspects of movement, such as the location, speed, and direction of a moving object.
Therefore, magnocellular (M) and parvocellular (P) neuronal pathways that originate in the retina and project to separate M- and P-dedicated layers of the lateral geniculate nucleus (LGN) situated in the thalamus.

Two snapdragon plants are crossed. One plant produces red flowers and the other plant produces white flowers. The cross between these two plants produces snapdragon plants with pink flowers. Which statement explains why the offspring have pink flowers? *
A. The offspring have two copies of the allele that codes for pink.
B. The offspring have one allele that codes for red and one allele that codes for white.
C. The flower color is determined by the dominant parent.
D. The flower color is determined by environmental conditions.
Answer:
The answer in B) The offspring have one allele that codes for red and one allele that codes for white.
Explanation:
Let's say that the red flower has Bb, and the white flower has bb. In a punnet square you'd get 50% being Bb and another 50% being bb. The allele bb would be pink.

Thrombocytopenia is characterized by an insufficient number of ____________ due to low production in the bone marrow or ____________ breakdown outside the bone marrow. Blood flow to the ____________ can stop completely and heart attack or stroke can result from untreated ____________ . An inherited clotting disorder with many forms, generally called ____________ , causes a deficiency in clotting factor. In all forms of this disorder, even the slightest bump causes ____________ in the joints.
Answer:
The correct words are - platelets, increased, tissue, thromboembolism, hemophilia, and bleeding.
Explanation:
Thrombocytopenia is a condition in which the number of platelets decreases significantly in the blood due to less production from the bone marrow or higher or increased breaking down of the platelets.
If the flow of the blood stops completely in between the heart and muscles and can lead to stroke in an individual if thromboembolism is not treated. Hemophilia is a blood condition that is a genetic disorder and inherits from the parents. In which blood does not clots and slightest bumps can lead to bleeding.

In what way are the bacteriophage and E. coli alike?
F They contain antibodies.
G They reproduce by mitosis.
H They have identical genomes.
1 They lack membrane-bound organelles.
Answer: G
Explanation:
Bacteriophage and E. coli alike as they lack membrane-bound organelles. The correct option is I.
What is Bacteriophage?Bacteriophages are viruses that infect bacteria. In fact, the term "bacteriophage" literally means "bacteria eater," because bacteriophages eat the cells of their hosts.
Bacteriophages are viruses that cause bacteria to become infected but are not harmful to humans.
To reproduce, they enter a bacterium, multiply, and then rupture the bacterial cell to release new viruses.
Bacteriophages and E. coli are both prokaryotic cells, which means they lack membrane-bound organelles found in eukaryotic cells such as mitochondria, Golgi apparatus, and endoplasmic reticulum.
Bacteriophages and E. coli are both unicellular organisms that reproduce asexually through binary fission rather than mitosis.
Bacteriophages, on the other hand, are viruses that infect and replicate within bacteria, whereas E. coli is a type of bacteria.
Thus, the correct option is I.

Hello there, mate! Let's solve together:
With the end goal for cells to endure, they require supplements as glucose and minerals in addition to oxygen.

Compared to the endocrine system, the nervous system has afaster response, but the signal does not last as long.slower response, and a signal that does not last as long.faster response with a longer-lasting signal.slower response with a longer-lasting signal.
Answer:
Has a faster response, but the signal does not last as long.
Explanation:
The nervous system uses action potentials to transmit signals. Action potentials have a short duration and travel fast through neurons to inform in a fast way about different stimuli and allow rapid answers. On the other hand, the endocrine system uses chemical molecules to transmit their signals. As they travel through blood or together with other molecules, their signal is not transmitted as fast as in the nervous system. However, when they reach their destination and interact with the proper molecules, they start a series of changes that have a lasting effect in contrast with the nervous system.
Many different relationships exist between organisms in an ecosystem. These relationships include competition for food, shelter, and
other resources as well as predation in which one organism kills and consumes another for food. There are also symbiotic
relationships. Symbiosis is a close relationship between two species in which at least one species benefits. For the other species, the
relationship may be positive, negative, or neutral. There are three basic types of symbiosis: mutualism, commensalism, and parasitism.'

The connections that demonstrate commensalism are as follows:
A) Hermit crabs use the shells of dead snails for homes.
B) Egrets perch on the back of cows and eat the insects that have been disturbed as the cattle forage for food.
So, the correct options are A and B.
What is Commensalism?One organism benefits from commensalism, a type of symbiotic relationship between two species in which the other is neither harmed nor helped. To put it another way, one organism gains, while the other is unaffected. When a bird builds its nest in a tree, it is engaging in commensalism because it not only provides shelter to the bird but does not benefit the tree in any way.
Some examples that illustrate the following are some relationships that show commensalism:
A) Hermit crabs live in the shells of dead snails.
B) As the cows graze for food, the heron sits on their backs and eats the pesky insects.
So, the correct options are A and B.
