Answers

A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. In contrast, animal cells have many, smaller vacuoles. Plant cells have a cell wall, as well as a cell membrane. Animal cells simply have a cell membrane, but no cell wall.

Answer:

A difference between plant cells and animal cells is that most animal cells are round whereas most plant cells are rectangular

Plant cells have a rigid cell wall that surrounds the cell membrane

Place the phases of a stem cell into the correct order.

A.differentiation, mitosis, specialization

B.gene expression, differentiation, mitosis

C.mitosis, gene expression, differentiation

D.mitosis, specialization, gene expression

Answers

Answer:

C. Mitosis, Gene expression, differentiation

Explanation:

Stem cells are referred to as undifferentiated cells which has the ability to develop into new specialized cells via cellular differentiation. The stem cell initially undergoes MITOTIC division to form new stem cells.

This stem cells then undergo GENE EXPRESSION by turning off some genes and turning on some in order to specialize the cell type. After this, the cell becomes DIFFERENTIATED i.e becomes another type of cell

Place the phases of a stem cell into the correct order.

The correct order would be mitosis, gene expression and then differentiation.

Stem cells can be defined as undifferentiated cells that possesses the ability to develop into many other different cells of the body. Before a stem cell becomes differentiated, the stem cell undergoes growth, mitosis and then information from the gene (DNA) in the cell will be needed to determine the type of cell it will become and be expressed before differentiating and becoming specialized to give rise to a particular type of cell.

Answers

the dry biomes are desert and tundra

Answer:

The desert and tundra biomes have very different temperatures as well as extremely different plants and animals. The desert can get very hot during the day, but cool off quickly at night. It has sandy soil and supports very little plant life. Animals found in the desert include lizards, javelinas, Gila monsters, coyotes, bobcats, scorpions, and kangaroo rats. The tundra is cold, dry, and often dark. The average temperature is about 10°F. The soil below the surface is permanently frozen, and is called permafrost. A few types of plants grow during the short summer season. Animals found in the tundra include caribou, foxes, wolves, and Arctic hares.

3. Reproducing more slowly would be a good way to take advantage of plentiful resources.

4. Reproducing more rapidly would be a good way to take advantage of plentiful resources.

Answers

Answer: 3. Reproducing more slowly would be a good way to take advantage of plentiful resources.

Explanation:

Hydra reproduce by both sexual and asexual modes of reproduction. In the case of asexual reproduction the bud develops on the parent body and derives nutrition from parent body, matures and finally get detached from the parent body. During asexual reproduction many buds will develop and live as an individual organism this will reduce the availability of resources like habitat, food, and others. Thus if the organism reproduces slowly then it will take advantages of many resources without experiencing the scarcity of resources.

The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.

Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.

In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour  at cellular, tissue, organs and organ system level.

Unicellular organism has simple body organization and multicellular organism have complex body organism.

Answer:

A and C

Explanation:

The sun itself is light energy and the heat that you feel from the sun is thermal energy.

Light and Thermal energy is used when air is warming in the sunlight.

Energy is emitted by the sun some of which is radiated back and some enter the earth.Solar energy is created by nuclear fusion that takes place in the sun.

What is energy?The capacity or power to do work, such as the capacity to move an object of a given mass by the application of force. Energy can exist in a variety of forms, such as electrical, mechanical, chemical, thermal, or nuclear, and can be transformed from one form to another. Energy is a conserved quantity.The law of conservation of energy states that energy can neither be created nor destroyed only converted from one form of energy to another.

What will happen if ATP and NADPH are already used up at night?​

Answers

Answer:

If ATP and NADPH are already used up at night , the production of glucose will stop.

Explanation:

IMPORTANCE OF ATP AND NADPH -: To temporarily store energy, the light-dependent reactions generate ATP and either NADPH or NADH. In light-independent reactions, these energy carriers are used to drive the energetically unfavorable mechanism of "fixing" organically inorganic CO2.

ATP is the molecular energy "currency" in biological systems. All energy produced by living organisms' cellular respiration must end up being used as ATP to power it. NADPH is a hydrogen carrier molecule reduced by NADP (Nicotinamide Adenine Dinucleotide Phosphate). While the light-dependent reactions take place, energized electrons hop on to electron carriers excited by photon energy from the sun (On Photosystem 2) and finally get to Photosystem one.

If ATP and NADPH are already used up at night, the fixation of carbon dioxide into glucose will halt. In other words, the light-independent reaction of photosynthesis will stop.

There are essentially 2 reactions in photosynthesis:

light-dependent reactionlight-independent reaction

In the light-dependent reaction, radiant energy is used to excite electrons chlorophyll molecules while electrons in water replace the excited electrons. ATP and NADPH are generated in the process.

The ATP and NADPH produced during the light-dependent reaction of photosynthesis are essential for the reduction of carbon dioxide into glucose in the light-independent reaction.

Hence, unless the light-dependent reaction takes place to make ATP and NADPH available, there is no other way to produce the precursors for the fixation of carbon dioxide into glucose.
