Answer:

Peristalsis Is the CONTRACTION of Muscle Tissue That Helps Move and Break Down Foodstuffs. The WALLS of the alimentary CANAL include layers of smooth muscle controlled by the autonomic NERVOUS SYSTEM. Alternating contraction and relaxation of these muscles is called peristalsis.

Answer:

GAMETE:

A gamete is a haploid cell that FUSES with ANOTHER haploid cell during fertilization in organisms that sexually reproduce. In species that produce two morphologically distinct TYPES of gametes, and in which each individual produces only one type, a female is any individual that produces the larger type of gamete—CALLED an ovum— and a male produces the smaller tadpole-like type—called a sperm.

FUCTIONS OF GAMETES:

The function of gametes is to combine with the other type of gamete and thus combine their single set of chromosomes to create a new complete double set of chromosomes. Sperm cells have a layer called the “acrosome” which is made up of enzymes that let the sperm penetrate the membrane of an EGG cell.

Explanation:

Digestion in amoeba is intracellular TAKING PLACE within the cell. The food taken in remains in a food vacuole or gastric vacuole formed by the cell membrane and SMALL part of the cytoplasm. The vacuoles are transported deeper into the cells by cytoplasmic MOVEMENTS. Here they fuse with lysosomes that contain enzymes.

Materials required:

5 slices of bread

5 transparent sealable bags

Gloves

mask

Sticky labels

marker

Magnifying glass

5 - 7 cotton swabs

Lemon juice/water/apple juice/salt/sugar (at least two of these items are required)

Procedure:

We take the cotton swabs and run them over areas which have dust.

We then rub the dust from cotton swab over the first bread slice. We do the same with the other bread slices.

We seal the three bread slices inside three transparent sealable bags and put a sticker on the three bags, and write down using a marker on them. On the first sticker we write "Sample #1 - Dark Closet"; on second write "Sample #2 - Refrigerator", and on the third write "Sample #3 - Under Light" and we keep the first sample in a dark closet, second in a CORNER of the refrigerator where it doesn't get disturbed, and the third ONE in an area of the house which is most of the time brightly lit.

Now, we take the REMAINING two samples. Before we seal them in the bags we add either lemon juice/water/apple juice/salt/sugar. We keep these two samples in a place where they don't get disturbed.

Observations:

We observe the five bread samples EVERY alternate day at a fixed time of the day (say 2 pm). It is important that we observe them every alternate day without fail, and note down the observations in a table. The observations can be their physical APPEARANCE like colour, shape, amount of growth per day, texture, etc. We can also observe the mold under the magnifying glass (usually thread-like structures are seen on top of which there is a circular shape).

Precautions:

We should use masks and gloves for safety.

We should properly dispose of the bags (without opening) after the experiment is over.

Answer:

Good question! Weather is important in people's lives in many DIFFERENT ways. Weather, including winds, thunderstorms, hurricanes, and tornadoes, is REALLY just the earth's way of redistributing heat around its surface.

Heat from the sun causes ocean surface waters to evaporate near the equator; the heat is carried in the water vapor and is released during big thunderstorms and hurricanes.

Winds are caused by pressure gradients, which are formed by hot air rising or cold air sinking.

Weather is important to people in many different ways, but several major examples come to mind:

1) Weather controls the distribution of rain water on earth. All living organisms on earth require liquid water to survive, and HUMANS require fresh (not salty) water for drinking and AGRICULTURE (growing crops for food). Droughts can have a major impact on humans and have killed millions of people throughout history.

2) "Severe" weather such as hurricanes, tornadoes, and floods have a huge impact on human civilizations. An obvious example of this was Hurricane Katrina, which impacted a huge are of the gulf COAST of the U.S., killed nearly two thousand people, and displaced over one million people from their homes.

3) The first two examples show some of the negative impacts of weather, but weather has also played an important role in the distributions of humans on earth and the development of different cultures. The climate (the long-term weather of an area) ultimately determines if an area will be nice for people to inhabit. Throughout history, climate has influenced migrations of humans over the earth. For example, there is a prevailing idea in archaeology that humans migrated into North America from Asia during a time of colder climate and lower sea level.There are many ways that weather is important in people's lives; these are just a few examples.

ANSWER:

Viable seeds are living entities. They must contain living, healthy embryonic tissue in order to germinate. All fully developed seeds contain an embryo and, in most plant SPECIES, a store of food reserves, wrapped in a seed coat. Seeds generally "WAKE up" and germinate when soil moisture and temperature conditions are correct for them to grow (Miles and Brown 2007). Each seed type has individual needs--take a minute and read about their specific germination requirements.

Seeds Need the Right Environment to Germinate

Temperature, moisture, air, and light conditions must be correct for seeds to germinate. All seeds have optimal temperature ranges for germination (Table 1). The minimum temperature is the lowest temperature at which seeds can germinate effectively. The maximum is the highest temperature at which seeds can germinate. Anything above or below this temperature can DAMAGE seeds or make them go into dormancy. At optimal TEMPERATURES, germination is rapid and uniform.

All seeds need correct moisture to initiate internal processes leading up to germination. In field soil this is generally about 50-75 percent of field capacity. A fine-textured seedbed and good seed-to-soil contact are necessary for optimal germination. Aeration in the soil media allows for good gas exchange between the germinating embryo and the soil. Seeds respire just like any other living organism. They need oxygen and produce carbon dioxide (CO2). This carbon dioxide needs to be able to move away from the seed. If the soil or media is not well aerated due to overwatering or compaction, the CO2 will not dissipate and seeds can suffocate

Explanation:

Amoeba is a unicellular ORGANISM found in fresh water. In amoeba CARBON dioxide and ammonia are the main waster materials. These waste materials are excreted out by the process of DIFFUSION through general BODY surface. In amoeba, CONTRACTILE vacuoles also play some role in the removal of waste materials.

AnswEr :-

1. Cell MEMBRANE ⇒ To be a gate allowing transport into the cell of essential nutrients and movement from the cell of WASTE products.

2. Cytoplasm ⇒ Acts as a buffer and protects the genetic MATERIAL of the cell and also the cellular organelles from damage caused due to movement and COLLISION with other cells.

3. MITOCHONDRIA ⇒ The powerhouse of cells.

4. Nucleus ⇒ Controls and regulates the activities of the cell

Answer:

1. water FORMS on the cover by transpiration

2. plant will die due to lack of carbon dioxide

Explanation:

1. Transpiration is the process of water movement through a plant and its evaporation from aerial parts, such as leaves, stems and flowers. Water is necessary for plants but only a SMALL amount of water taken up by the ROOTS is USED for growth and metabolism.

2.Stunted growth. Plants take up less water or nutrient solution than NORMAL. Cures: When carbon dioxide levels are low, plants are not able to photosynthesize efficiently and their growth slows.

Explanation:

The most important FUNCTION of chromosomes is to carry the basic genetic material – DNA. DNA provides genetic information for VARIOUS cellular functions. These functions are ESSENTIAL for growth, survival, and reproduction of the organisms.

Histones and other proteins cover the Chromosomes. These proteins protect it from chemical (e.g., enzymes) and physical forces. Thus, chromosomes also perform the function of protecting the genetic material (DNA) from damage during the process of cell division.
