Answer: Carbon dioxide
Explanation:
The forests and phytoplankton are carbon sinks, which absorbs the green house gas carbon dioxide from the atmosphere for photosynthesis. The carbon dioxide from the atmosphere and water are used as reactant in photosynthesis to yield carbohydrates and oxygen as products. Thus the carbon dioxide level in atmosphere decreases. This is necessary for controlling pollution in the environment and reducing the environmental temperature as carbon dioxide can make the environment warm.

Check all that are TRUE about biodiversity. *
Ecosystem diversity is the number of different kinds of ecosystems.
Depending on the ecosystem, some species can unravel the whole ecosystem if the die.
Species diversity is the number of species in that ecosystem.
Biodiversity is not important because we are humans and we don't need are these other organisms on Earth.

Drag each label to the correct location on the diagram. Each label can be used more than once, but not all labels will be used.
The diagram shows some of the steps in the flow of energy through an ecosystem. The arrows represent the transfer of energy. Label each
arrow with the type of energy being transferred.
chemical
electrical
thermal
radiant
nuclear
Answer/Explanation:
=> The first arrow linking the sun and the plants represents transfer of RADIANT energy. The sun through its sunlight radiation provides energy for autotrophs such as plants to manufacture their food.
=> The second arrow from plants to rodent represents transfer of CHEMICAL energy. The chemical energy that is manufactured and stored between the molecules of the plant as food, is transferred to rodents as primary consumers.
=> Third and fourth arrow from the rodent to owl, and from the rodent to the wolf both represents CHEMICAL energy transfer.
=> Fifth arrow from the wolf to the surroundings show heat loss during metabolic processes in the wolf's body which represents THERMAL energy transfer from the wolf to the environment.
=> The width arrow from the wolf to decomposers also show THERMAL energy transfer as the wolf dies and decay, Hera is released.
The arrows represent the transfer of energy which are described as follows:
1. Radiant energy
2. Chemical energy
3. Chemical energy
4. Chemical energy
5. Thermal energy
Radiant energy is transferred through the first arrow connecting the sun and the plants. Sunlight gives autotrophic organisms like plants the energy they need to produce food. The transfer of chemical energy from plants to rodents is shown by the second arrow. Rodents are the main consumers of chemical energy that is produced and stored as food between plant molecules.
The third and fourth arrows, from rodent to owl and from rodent to wolf, respectively, both indicate the transmission of chemical energy. The fifth arrow shows heat loss from the wolf's body during metabolic activities, indicating thermal energy transfer from the wolf to the surrounding environment.

7. a) How does a vaccine relate to the virus that it protects against? (1 point)
Answer: A vaccine works by training the immune system to recognize and combat pathogens, either viruses or bacteria. To do this, certain molecules from the pathogen must be introduced into the body to trigger an immune response. These molecules are called antigens, and they are present on all viruses and bacteria.

In Linneaus's book Systema Naturae, minerals were originally included while classifying living things.
But, minerals were later removed from this classification. What characteristic of science does this show?
A. Scientific knowledge is rigid.
B. Scientific knowledge is permanent.
C. New evidence emerges by chance.
D. New interpretations are a part of science
Answer:
Option-D
Explanation:
Carolus Linnaeus gave the three kingdom classification of organisms that is plants, animals and mineral kingdom.
He included various features which were mostly morphological and kept living organisms into plants and animals and non-living things into his mineral kingdom. This mineral kingdom was later removed from the classification system.
The removal of the mineral kingdom shows that the interpretations can be a part of science and science is not permanent but changes with time. The advances and development in science shows are the results of new interpretations in science.
Thus, Option-D is correct.

Compare AND contrast primary and secondary succession.
Answer:
Primary succession occurs following an opening of a pristine habitat, for example, a lava flow, an area left from retreated glacier, or abandoned strip mine. In contrast, secondary succession is a response to a disturbance, for example, forest fire, tsunami, flood, or an abandoned field.In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area that was previously occupied by living things is disturbed, then re-colonized following the disturbance.
Explanation:
Answer:
The basic difference between primary and secondary succession is the presence of soil. When primary succession begins, soil is not present; in the case of secondary succession, soil is already in place.

E- Metaphase
F-Anaphase
What is cell cycle?A cell's growth and division are accompanied by a sequence of processes known as a cell cycle. A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide. The cell then exits interphase, goes through mitosis, and finishes dividing.
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase.
The chromosomes shorten and thicken during prophase. Chromosomes align in the center of the cell during metaphase. Chromatids split off at the centromere and migrate to opposite poles during anaphase. Telophase: Following the reorganization of nuclear envelopes around each cluster of chromosomes, two nuclei are created.

Hypothesize how the properties of water protect the aquatic organisms living in a temperate-
climate pond during both the summer and winter months.
Couple sentences
Answer:
Hydrogen bonds make water molecules spread out when they freeze. This makes ice less dense than water and allows ice to float. If ice did not float then oceans and lakes would freeze from the bottom up, killing marine life by trapping organisms in the ice. When ice floats, it insulates the water below, keeping it at around 4 degrees C or 40F, which does not freeze and allows fish to survive the winter.
