During the second trimester, a pregnant woman needs an additional _______ kcal per day.

1 answer:

4 0

I believe that during the second trimester, a pregnant woman need an additional 350 kcal per day. Dietary intake during pregnancy must provide energy that will ensure the full term delivery of a healthy newborn baby of adequate size and appropriate body composition. A pregnant women requires additional energy for the fetus and that explains the reason for the additional energy requirement.

1. MUSCLE TISSUE : allows the heart to contract
2. CONNECTIVE TISSUE : insulates the body
3. EPITHELIAL TISSUE : forms the outer, most protective layer of the body
4. NERVOUS TISSUE : allows the brain to respond to stimuli. Others include sensory input, integration, control of muscles and gland, homeostasis, & mental activity.

After differentiation, the various types of cells become specialized for a specific function. Their ______ relates to this _____

kykrilka [37]

Explanation:

The structure relates to their function

Their structural components (i.e. their makeup) determine their function (what they do). In specific cell types, collected proteins may function as a unit called an organelle.

Further Explanation:

In all eukaryotic cells mitochondria are small cellular organelles bound by double membranes make most of the chemical energy required for powering the biochemical reactions within the cell. this chemical energy is stored within the molecule ATP which is produced.

Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they

may increase metabolic reaction efficiency;
they allow cells to concentrate smaller fractions of enzymes and solutes separate proteins and molecules that may harm the cells by parceling them into membrane-bound organelles
for example, hydrolytic enzymes concentrated within vacuoles may degrade macromolecules like DNA and RNA within the cytoplasm.

Which of the following enzymes listed below are responsible for cancer cells ability to prevent aging of the cells and contribut

umka2103 [35]

Answer:

Telomerase

Explanation:

Repetitive regions at the ends of Chromosomes are known as telomeres and these are crucial for chromosomal stability. There is no gene present and they provide protection to internal parts of chromosome. The telomeres are eaten up slowly by ‘DNA REPAIR MECHANISM’ after many division cycles, which is considered as ageing. That why, a cell can divide only certain number of times.

Some cells have ability to express an enzyme telomerase that maintain the length of telomere. The telomerase enzyme contributes to cell immortality by rebuilding the damaged telomere. Thus telomerase enzyme is necessary for cancer initiation and survival of tumor. Telomerase enzyme can make its own DNA by using its RNA as template . It extends the overhang strands of DNA by using a comlementary DNA.
