Explanation:

Plants provide protective cover on the land and PREVENT soil erosion for the following reasons: Plants slow down water as it flows over the land and this allows much of the rain to SOAK into the GROUND. PLANT roots hold the soil in position and prevent it from being blown or washed away.

a unit of information inside a CELL which controls what a living thing will be like. Genes are passed from parents to children

Chemical structure of genes. Genes are composed of deoxyribonucleic acid (DNA), except in some viruses, which have genes consisting of a CLOSELY RELATED compound called RIBONUCLEIC acid (RNA). A DNA molecule is composed of two chains of nucleotides that wind about each other to resemble a twisted ladder.

ANSWER:

Yes , ENZYME production is realted to growth of bacteria.

Enzymes cannot REPRODUCE themselves. They speed up chemical reactions WITHOUT getting used up themselves. ... When the waste materials are very COMPLEX (such as pond sludge), bacteria actually produce enzymes to break down the complex waste into simple compounds that the bacteria can consume.

For detecting human genome mutations, SNPS, and rearrangements, publications often recommend from 10× to 30× depth of coverage, depending on the APPLICATION and statistical MODEL. For RNA sequencing, researchers usually think in terms of numbers of millions of READS to be sampled.

here is your answer:-

However, most carbon dioxide is transported as bicarbonate. As blood flows through the tissues, carbon dioxide diffuses into RED blood CELLS, where it is converted into bicarbonate. ... Additionally, hydrogen ION is released from hemoglobin, thus allowing oxygen to bind to hemoglobin as blood flows through the lungs.

ANSWER:

Answer:Milk is CONVERTED into CURD by the bacteria CALLED lactobacillus.It multiples in milk and creste a chemical called lactic acid which convert mik into curd. Milk is converted into curd or yogurt by the process of fermentation. During fermentation, the bacteria use enzymes to PRODUCE energy (ATP) from lactose.

ANSWER:

what's your QUESTION?????..........??????...

Answer:

Respiration in HUMAN beings takes place through a SPECIAL system called as respiratory system.This involves nostrils, nasal cavity, larynx, bronchi, bronchioles ending in alveoli inside the lungs. Lungs are designed in such a way that they are lined by a thin membrane to facilitate the exchange of gases.

Bronchi and bronchioles are the parts of respiratory system located in the lungs.

*Primary bronchi are the structures which arise by the bifurcation of the wind pipe before entering the lungs. Primary bronchi divide and give rise to secondary bronchi. Bronchioles are the small tubular extensions of REPEATEDLY dividing secondary bronchi inside the lung.

*Bronchi end in bronchioles. Each bronchi divides at least 20 times to form smaller bronchioles    Bronchioles end in small tubular structures called as alveolar tubes.Bronchi are made up of fibrocartilaginous layer. Bronchi serve as tubes of air conductors. Bronchi are larger in diameter  

*Bronchioles branch into many alveolar tubes. Bronchioles are lined by smooth muscles. Bronchioles are air conductors and others are respiratory GAS exchangers. Bronchioles are smaller in diameter.

*Alveoli are richly supplied by blood vessels which help in exchange of gases on the alveolar membrane.

Explanation:

phylum Porifera

1)These animals are with simplest body plan and are called as 'sponges'

2) These are aquatic animals most of them are marine and few are fresh water dwellers

3) they have assymetrical body

Phylum- Cnidaria

1) Body of these animals is cylindrical or UMBRELLA- like body . If it is cylindrical it is called as ' Polyp ' and if it is umbrella like it called as 'Medusa'

2) Most of these animals are marine . Only few are fresh water dwellers

Phylum Platyhelminthes

1) Body of these animals is slender and flat like a leaf or strip . HENCE they are called flatworms

2) Most of these animals are endo parasites

Phylum Aschelminnthes

1) Body of these animals is long THREAD like or cylindrical . Hence they are called as round worms

2) These animals are either FREE living or endoparasites. Free living animals are either aquatic or terrestrial

Phylum Annelida

1) Body of these animals is long , cylindrical , and metamerically segmented

Virus - They are a nucleoprotein particle, nucleic acid can be either RNA or DNA. They contain capsid covering .ie. a protein LAYER FOUND around the nucleus. They lack a true cell membrane. They are large-sized. They infect all types of organisms.

VIROIDS - are an infectious RNA particle. They are devoid of any capsid caoting. They contain only RNA. They are of SMALL size. They infect only plants.

PRIONS - They are proteinaceous infective particles. They do no contain any nucleic acid. They generally cause an infected individual's DNA to START producing an altered form of a protein that they would normally produce. Their protein is called a prion protein (PrP). They cause disease by infecting this protein in misfolded forms.

Hope this helps you.

Explanation:

Although it is happening every hour of every day, all over the world, the story of egg meeting sperm is still a tale worth telling. Millions of candidates set off on a long and perilous journey with a single target at the end, and if the candidates reach their target, something completely unique is created. But before we GET to the end, let’s take a closer look at the journey.

Hundreds of millions of sperm vie for a single egg cell. The sperm cells are streamlined in design for this purpose: a long tail to help them move, lots of mitochondria to power that movement, GENETIC information to pass on, and enzymatic PROTEINS to get into the egg cell. The proteins are stored in a cap at the front of the sperm known as an acrosome - this is the part that first contacts the egg. The tail is called a flagellum, and it uses the energy made by the mitochondria to move the sperm forward. Flagella use a lot of energy, so they’re kept dormant until sperm enter the vagina. Sperm are haploid; they contain one set of 23 chromosomes. They are created by the cellular division process known as meiosis, which creates 4 sperm from a single germ cell. They’re also very small, only about 50μm long. Sperm are ejaculated in semen, a basic fluid with a PH of about 7.4.

The sperms’ target, is the egg. Since it is so much bigger than sperm, the egg is the source of cytosol and organelles,particularly mitochondria, for the future zygote. Unlike sperm, the egg has not completed meiosis - it’s stuck in the Metaphase II stage of division. This means that the egg is haploid but with sister chromatids still attached to each other. Also unlike sperm, the meiotic division to create eggs, oogenesis, only makes one viable egg. The egg is covered in a thick outer coating known as the zona pellucida, a layer of carbohydrate-covered proteins that surrounds the plasma membrane. The zona pellucida helps protect the egg and is responsible for mediating the initial meeting of sperm and egg. Cortical granules filled with enzymes line the inside of the cell membrane, and will help make sure that only one sperm can fertilize the egg.
