Answer:

A change in the integrin proteins from the cell's surface.

Explanation:

Integrin proteins' principal function is to attach the cell to the basal lamina. Also, they transmit signals from the extracellular matrix to the interior of the cell. A change in the integrin could result in loss of connection between the mutated cell and the basal lamina.

Cadherin proteins connect one cell to another. A change in these proteins will not result in the loss of connection between the metastatic tumor cell and its extracellular matrix. It most likely will affect the communication and adhesion of cells.

A change in connexins will disrupt the communication between cells but not the connection to the lamina basal. Connexins are transmembrane proteins that connect one cell to another with gap junctions that allow the passage of different components from cell to cell.

Answer:

C. Uterus

Explanation:

Uterus is the female reproductive system.

The female reproductive system serves a number of purposes. It aids in sexual reproduction in addition to enabling sexual activity.

You make eggs using your ovaries. During ovulation, these eggs are subsequently moved to your fallopian tube where sperm fertilization may take place. The fertilized egg is then transferred to your uterus, where the lining of the uterus has expanded due to the typical hormones produced during your menstrual cycle, also known as your reproductive cycle.

The fertilized egg can implant into the thicker uterine lining once it's within your uterus and continue to grow there. Your menstrual period causes the uterine lining to shed if implantation doesn't occur.

Therefore, Uterus is the female reproductive system.

Answer: An invasive species is the one which compete for resources with the native species.

Explanation:

Wild Parsnip is an invasive species of plant in Europe and Asia. It grows on the roadside and the seeds of the plant disperse very easily by wind and water agents. It spreads easily and compete with native species for resources like soil nutrients, water, and others. It produces a chemical that causes rash in the human skin and the human skin becomes sensitive to sunlight resulting in development of blisters and rashes on the skin.

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.

QUESTION :::::

Which gas is most necessary for plants to do photosynthesis?

A. carbon dioxide

B. nitrogen

C. oxygen

ANSWER ::::

carbon dioxide

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight. for photosynthesis. Carbon dioxide enters through tiny holes in a plant's leaves, flowers, branches, stems, and roots. Plants also require water to make their food.

CAN I GET THE CROWN PLEASE I HOPE IT HELPS THANKS

Answer:

The correct answer is - tend to lose water by osmosis since their internal salt concentration is lower than that of seawater.

Explanation:

In freshwater fishes, the body of fishes has a higher salt concentration inside their body than the surrounding water, water enters through the osmosis process. Without any active regulation of this process, fishes would swell and get bigger and bigger. They have specialized cells called chloride cells in gills to take ions from water as they do not have kidneys.

In contrast, the marine fishes have a lower salt concentration in their body than surrounding water of sea or ocean and they lose water continuously and to compensate for this they need to drink water regularly.

Answer:

D. A nitrogen base has been added to the DNA molecule.  

Explanation:

You can see that the sequence for the nitrogen bases are in the exact same order after the exposure, this rules out A.  You can count how many bases there are, 7 before and 8 after so it cannot be B. Lastly, given that they are in the same order as were before and that a base has been added, you can see that no bases were replaced (so not C) and that D is your 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.

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.
