➩Reproduction:

Reproduction is a process by which living organism produce new organisms of same species (of their own kind)

Reproduction is neccessary for the survival and increase in population of species. It ensures continuity of various species on earth. In simple words if organisms will not reproduce there population will decrease and species will become extinct.

➽Mainly there are two types of Reproduction

(i) Sexual reproduction

(ii) Asexual reproduction

➩Sexual Reproduction

→ In sexual reproduction two individuals are involved to produce a new individual (male and female)

→The entire reproduction process takes longer time and more energy.

→ Population increases relatively slowly.

→ It involves more variations.

→ Species can adapt to an environment which changes.

→This leads to evolution.

→ For example:Homosapiens(Human beings)

Answer: CONNECTIVE TISSUE is the most abundant tissue in the body which are widely separated from each other and intercellular substance (matrix) is present in considerably larger amounts. The principal cell of connective tissue are fibroblasts which makes fibres found in almost all connectiv tissues. Some are solid and strong (bone), while others are fluid and flexible( blood).

Explanation:

Connective tissues usually contain fibres present in the matrix which may be of semisolid jelly-like consistency or dense and rigid, depending upon the position and function of the tissue. There are three main types of connective tissue which include:

--> Loose connective tissue

--> Dense connective tissue and

--> specialised connective tissue.

The bone and the blood are considered to be an example of specialised connective tissue. This is so because they both contain a number of different tissues with specialized cells and unique ground substances.

The BONE consists of osteoblasts, osteocytes, and osteoclasts. It is considered to be a specialised connective tissue because the bone cells are surrounded by a matrix of collagen fibres strengthened by inorganic salts, especially calcium and phosphate.

The BLOOD consists of red blood cells, white blood cells, platelets. It is considered to be a specialised connective tissue because the blood cells are surrounded by fluid matrix known as plasma and connecta with other cells through its transport functions.

In COMPARING the concentration of connective tissue cells or bone and blood, the connective tissue cells of bone comsist of fibre and collagen which makes it dense and rigid while the connective tissue cells of blood does not contain any fibre, therefore it's flexible.

Answer: Proteins in the "tail" of the phage bind to a specific receptor (in this case, a sugar transporter) on the surface of the bacterial cell. Entry: The phage injects its double-stranded DNA genome into the cytoplasm of the bacterium.

Explanation:

Answer:

Una enzima es una sustancia, generalmente una proteína, en la célula de un organismo que acelera las reacciones químicas.

Durante el pardeamiento enzimático, una enzima llamada fenolasa y otro compuesto orgánico que se encuentra en las células de la fruta llamados fenoles pasan por una reacción de oxidación cuando se exponen al oxígeno. La fenolasa regula la reacción, convirtiendo los fenoles en melanina.

Por lo general, las enzimas de la fruta están encerradas en tejido. Las enzimas están metidas en sus células, trabajando para madurar la fruta. Pero cuando esas células se descomponen, ya sea por una causa externa como si alguien muerde o corta la fruta o por causas naturales como el envejecimiento, las enzimas se liberan y entran en contacto con el oxígeno, lo que desencadena la reacción química y hace que la fruta se vuelva marrón.

Answer:

b.Store water

Explanation:

Here we are looking at a vegetable cell. And specifically, the X letter is labeling a vacuole, which we can recognize by its size.  

We can find vacuoles either in animal or vegetable cells. They are essential to the correct functioning of the cell.

Now we are going to describe a vegetable cell vacuole.

Usually, they occupy a central place on the vegetable cells. They are big organules, representing almost 90% of the total cell volume. They are the biggest-sized organelle of vegetable cells.

Vacuole formation is thanks to the fusion of many vesicles release by the Golgi complex, and sometimes, with the RER intervention. There are different types of vacuoles according to their function, and many times, a single cell might carry different types of vacuoles. These organelles harbor diverse fluids, among which there are water and enzymes. Eventually, they can also contain solid substances such as proteins, salts, and sugars.

Vacuoles accomplish different functions. The main one is to keep turgor, store waste elements, and substance degradation. Here we are going to focus on the turgor function that involves water storage.

Turgor is a measure of hydrostatic pressure against the cell walls and controlled by these organelles. Vacuoles incorporate substances in their interior such as ions, creating an osmotic environment variable concerning the cytoplasmic one. This environmental variability produces a water flow from inside to outside and vice-versa. The capability of water storage is crucial for vegetable cells.

About the question:

You will find the completed strand in the attached files

Answer and Explanation:

First, we need to recognize each strand, the original one and the complementary one. We can recognize the original strand because bases are already given. So,

Now we need to recognize and pair the bases. Names are written with their letters.

Nitrogenated bases that form nucleic acids correspond to purines and pyrimidines. Adenine and guanine derive from purines, while Thymine and Citocine derive from Pyrimidines.  

In the DNA molecule, Adenine (Purine) forms pairs with Timine (Pyrimidine), while Guanine (Purin) pairs with Cytosine. Two hydrogen bonds join the A-T pair, and three hydrogen bonds join the G-C.

Once we drag the base labels to their targets, we need to recognize each of the strain extremes.

One of the extremes has a phosphate group, which is named 5´. The other extreme has a hydroxyl OH named 3´. Both of them are readen in the 5´to 3´ direction. The polymerase enzyme reads the original strand in 5´ to 3´ mode, and the molecule lecture goes from 3´to 5´.

So, by looking at the labels, we will recognize the phosphate extreme and the hydroxyl one. We will place in the superior extreme of the original strain the phosphate group 5´ and in the other extreme the OH 3´. These positions will give us the direction reflected by the arrow. The complementary strand will have the same extreme labels but in opposite places. So first we will place the OH 3´ label in the superior extreme, and the phosphate 5´label in the inferior extreme, defining the direction reflected by the arrow.

Answer:

Suspension feeding involves collecting food particles like small organisms, organic matter, detritus which are suspended in water, often using some form of filtration.

Suspension feeders catch food or organic material from the water using tentacles or spiny arms

where as

Deposit feeding involves feasting on detritus and organic matter that have settled on the ocean floor.

Deposit feeders pass sand, mud, water or sediment into their mouths using mucous-covered tentacles or arms etc.

Explanation:

Suspension feeding ingests the food particles which are suspended in water, while deposit feeding ingests sediments and aquire foods.

Deposit feeders may be defined as those aquatic organisms that forage on organic matter that settled down on the bottom.

Suspension feeding maintains the water quality in the aquatic environment, while deposit feeding enhances oxygen level and nutrient cycling.

Suspension feeding occurs similarly to filter-feeding that only ingests suspended particles. While deposit-feeding ingests the deposited particles like detritus, organic matter, etc.

Therefore, it is well described above.
