Answer:
A - It allows for genetic variation among organisms.
Explanation:
Its basically sex or sexual reproduction. Which later allows for genes to spread and vary. Which create families in animals and humans.
Because Meiosis is Sexual Reproduction

Explanation:
The given question is incomplete, the complete question is:
Steroids are cholesterol based hormones. Nerve Growth Factor (NGF) is a water-soluble signaling molecule. Both have essential roles in cell function and organismal development. How are they received by the cell? A) Receptors for steroids are located in the plasma membrane and receptors for NGF are located in the cytosol. B) Receptors for steroids and NGF are located in the plasma membrane, C) Receptors for steroids and NGF are located in the cytosol, D) Receptors for steroids are located in the cytosol and receptors for NGF are located in the plasma membrane
Answer:
The correct answer is option D, that is, for steroids the receptors are situated in the cytosol and for NGF the receptors are situated in the plasma membrane.
Explanation:
NGF or the nerve growth factor is the water-soluble signaling molecule, and steroids are the cholesterol-based hormones. Both possess important functions in cell activities and the development of organisms. They are attained by the cells with the help of receptors for steroids situated in the cytosol, and the NGF receptors situated in the plasma membrane.
The plasma membrane permits the hydrophobic molecules, that is, water-insoluble molecules to pass through it. The water-insoluble molecules are the steroids, therefore, it can easily go through the plasma membrane and thus possess receptors within the cytosol. On the other hand, the water-soluble or the hydrophilic molecules are the NGF, they fail to pass through the plasma membrane, and thus, possess receptors on the plasma membrane.
Answer: Malignant tumor-
cancer cells are contained within their tissue.
Maglinant tumor-- Cells of this type of tumors have the potential to , escaping their tissue and spreading to other locations within the body.
Benign tumour-pre-cancerous cells highly disorganized metastasize.
Explanation: Tumor is an abnormal growth in the cell.
Benign tumor is a tumor that do not spread within the cell and are not cancerous. The can grow to very large and are removed by operation. It can be very dangerous when its big and press other tissues especially when located in the brain. It may not require any treatment when it is not threatening. Example of benign is fibroid
Malignant tumour are tumour that are cancerous and can spread to other tissues. They can be transported via the blood stream to other tissues. Malignant tumour grows fast and can spread to nearby tissues example is breast cancer when not diagonize earlier can spread to other tissues. They required medical attention and can be removed through operation, some require chemotheraphy. Some malignant tumour grows back even after removal.
