A) 04
B) 05
C) O9
D) 10

Answers

Answer 1

Answer:

10

Explanation:

easch couplet presents the user with 2 alternatives and exclusive sets of character's.

Answer 2

10 couplets should your key have. If you are building a dichotomous key, and you have 10 species to identify. Hence, option D is correct.

What is dichotomous key?

A dichotomous key, a crucial piece of scientific gear, is used to discriminate between diverse species according to their visible traits. Users must choose one of two possibilities to answer a series of questions that make up dichotomous keys.

A dichotomous key in the identification of trees, for instance, would ask whether the tree has leaves or needles. The key then leads the user down one set of questions if the tree has leaves; if the tree has needles, a different set of questions is shown.

The three most prevalent types of dichotomous keys are nested, connected, and branched. Each sentence has the appropriate response written next to it in nested type.

Thus, option D is correct.

Answers

Answer:

ecosystem

Explanation:

An ecosystem refers to the interaction/relationship between the biotic parts of a habitat with one another and also the abiotic parts. The biotic parts refers to organisms that possess life in them e.g plants, animals, microbes etc while the abiotic parts refers to the inanimate things e.g rocks, sea, land, soil etc.

Therefore, according to this question, an ecologist looking at communities of different species interacting with each other and the abiotic factors of their environment is studying ECOSYSTEM.

Why postharvest physiology is important to maintain sustainable food supply on this planet. Please give named examples and discuss various biological factors associated with produce deterioration after harvest

Answers

Answer:

Postharvest physiology plays a fundamental role in extending the shelf-life and quality of plant products. An example of postharvest physiology methodologies is by reducing the temperature to improve shelf-life before consumption

Explanation:

Postharvest physiology refers to the methodologies used for extending shelf-life and quality, thus being a critical issue in food systems. Postharvest approaches include chemical treatments, temperature reduction, cleaning and disinfection methods, etc. Crop varieties are genetically selected in order to maintain nutritional qualities of stored seeds for a long time after harvest. These seeds are also controlled during storage by using postharvest handling practices (e.g., chemical and enzyme inhibitors that extend shelf life).

Answers

Answer:it was heated and under pressure

Explanation:

Metamorphic rocks are formed from existing rocks, under high temperature and high pressure. This process is called metamorphism.

What is a metamorphic rock?

Metamorphic rocks are those rocks that are formed from different kinds of rock like igneous, sedimentary, or gneiss rock under high pressure and intense temperature. They are rigid in nature.

In the formation of metamorphic rocks, firstly existing rock is broken down into small particles by physical, chemical, or biological agents. The process of breaking down rock is called weathering.  Then erosion and transportation of these particles take place by the wind, water, or any biological agent.

The next step involves compaction after sedimentation. Thus, metamorphic rocks are formed from existing rocks.

How are the processes of cellular respiration, photosynthesis and carbon cycle related to each other?

Explain how one of the processes discussed in this module (photosynthesis, cellular respiration or the carbon cycle) apply to both the Law of Conservation of Matter and Law of Conservation of Energy.

Answers

Answer:

1.Mitochondria is considered as the power house of the cell as it helps in producing large amount of energy in the form of ATP (adenosine triphosphate) that is used in driving various cellular activities.

2.Through a process called photosynthesis, plants use energy in sunlight to turn a gas called carbon dioxide and water into sugar. Plants then use this sugar to grow. At the same time, plants produce a gas called oxygen as a waste product, which is lucky for us and other animals because we need oxygen to breathe!

3.Cellular respiration and photosynthesis are important parts of the carbon cycle. The carbon cycle is the pathways through which carbon is recycled in the biosphere. While cellular respiration releases carbon dioxide into the environment, photosynthesis pulls carbon dioxide out of the atmosphere.

4.Cellular respiration uses oxygen and has it's waste product of carbon dioxide (CO2). How does photosynthesis demonstrate the law of conservation? ... The AMOUNT of carbon-dioxide atoms released by respiration are EXACTLY EQUAL to the atoms of these materials contained in the oxygen and carbon converted.The Law of Conservation of Matter states that matter cannot be created or destroyed. The carbon cycle is an example of the Law because the same carbon atoms are being recycled through the carbon cycle. ... Carbon is used for energy, and some is stored for growth.

How was the rotation rate of Jupiter's core determined?
-by observing the Great Red Spot
-by watching lo move across the disk of Jupiter
-by radio observations of Jupiter's rapidly spinning magnetosphere
-by measuring the oblateness of Jupiter's disk

Answers

Answer:

C. by radio observations of Jupiter's rapidly spinning magnetosphere

Explanation:

Jupiter refers to one of the planetary bodies in the solar system. It is considered to be the largest (twice as large or big as every other combined) planetary body and the fifth (5th) from the Sun.

Jupiter is a planet that rotates rapidly and as a result it is referred to as being noticeably oblate. It has the fastest rotation rate among the planets of the solar system because it completes a rotation about an axis in 9.9 hours.

The rotation rate of Jupiter's core was determined by radio observations of Jupiter's rapidly spinning magnetosphere.

rattlesnake population
Wc
A decrease in the rattlesnake population will cause an increase in the kangaroo

Answers

Answer:

The answer is option A "A decrease in the kangaroo rat population will cause a decrease in the coyote population"

Explanation:

Climate is a significant ecological impact on environments. Changing Climate influences biological systems in an variety of ways. For example, warming may constrain species to relocate to higher scopes or higher rises where temperatures are more helpful for their endurance.

Environmental change not just influences biological systems and species straightforwardly, it likewise communicates with other human stressors, for example, advancement. Although a few stressors cause just minor effects when acting alone, their combined effect may prompt emotional natural changes. For example, environmental change may worsen the pressure that land improvement puts on delicate water front zones. Also, as of late logged forested zones may get defenseless against disintegration if environmental change prompts increments in substantial down pour storms.
