Answer:
The answer would be D!
Explanation:
A hydrogen bond is one of the strongest molecular bonds.
I think its the c. archaebacteria because there are hundreds of species of archaebacteria living under the sea.....
and bacteria is harmful to all lifes of species..
Since IDK which two you would choose, I'll just list all of them: fish have developed a light, streamlined body to get through water quickly to evade predators with and swim with ease, owls have big eyes so their pupils can get enough light to see in the dark since they're nocturnal, their light bodies and special (Fluffy???) flight feathers let it fly with virtually no sound, allowing it to sneak up on prey, tortoises have a large, hard shell for protection from predators and provides a mobile home on their back! Bats may be practically blind but that doesn't stop them when using echolocation to detect prey and chase it no matter what moves they make or obstacles in the way, snowshoe hares have big feet to sit on top of the snow in the cold winters where they live, their fur also changes colors as the snow melts and the plants start coming back in the more warmer seasons, poison dart frogs, sorry, IDK, cacti have developed spines all over them as self defense, (from what IDK) and they can last a long time without water (I think, don't quote me on that ^^') hope this helps
Molecules brought in and used in the calvin cycle - Carbon dioxide 
, Ribulose bisphosphate (RuBP)
Molecules produced during the calvin cycle that leave the cycle - a few of the glyceraldehyde-3-phosphate (G3P), NADP+
Molecules used and regenerated within the calvin cycle - most of the Glyceraldehyde-3-phosphate (G3P) , NADPH
<u>Explanation:</u>
Calvin cycle is the light independent reaction that takes place in the stroma of the chloroplast. Calvin cycle uses ATP and NADPH produced during the light reaction. Calvin cycle occurs in 3 steps, they are:
1. Carbon fixation - combines with Ribulose bisphosphate (RuBP) to form 2 molecules of 3-phosphoglyceric acid (3-PGA).
2. Reduction - ATP and NADPH is used to convert 3-PGA into glyceraldehyde-3-phosphate (G3P).
3. Regeneration - some G3P molecule form glucose while other regenerates to form RuBP acceptor.
1. Answer;
It facilitates the movement of the fetus towards the pelvic girdle thus the child is born headfirst.
Explanation:
- During labor the pelvic floor facilitates movement of the fetus towards the pelvic girdle by resisting the descent of the presenting part. This makes the fetus to rotate forwards and therefore results in majority of the fetus being born headfirst.
2. Answer;
Purple pushing lead to development of pelvic floor problems.
Explanation
;
- Purple pushing involves the midwife instructing a woman to hold her breath for ten seconds while forcefully pushing down during a contraction.
- in the second stage instead of waiting for the mother to feel the instant urge of pushing which lead to development of pelvic floor problems.
3. Answer;
Exercise can help to strengthen the abdominal muscles and reduce the appearance of diastasis recti.
Explanation;
- By contracting transversal abs muscles they strengthen and pull the muscles inwards.
- The diastasis recti reduce with time due since the rectus muscles come close to each other enabling a human being to live a normal life because flexion, bending and stability becomes easy.
4. <u>Answer</u>
- Pelvic floor muscles
- Stomach muscles
- Abdominal muscles
- Perineal muscles
- Uterine muscles
<u>Explanation</u>
- Abdominal muscles are stretched to their limit by term. They greatly decrease the ability to perform strong contraction.
- Pelvic floor is vulnerable to muscular and neurological injury during labor and delivery.
- Perineal muscle tightening strengthens the pubococcygeus muscle and increases its tone.
5. Answer and explanation;
- Sports that can lead to falling down e.g. skating
- Sports that may involve altitude change
- Exercises that involve lying flat on your back
- Exercises that involve holding o breath
- Motionless standing
6. Answer
Yes
Explanation
;
- Exercise maintains physical fitness, health and wellness aiding growth to the unborn since the mother gains enough strength and energy and there is proper blood flow.
- Many pregnant women tend to gain weight which may lead to health difficulties for example struggling to breath. The pregnant lady is able to cope with labor and she is able to get back in shape after the baby is born.
7. <u>Answer</u>;
One is supposed to get up slowly and gradually to avoid dizziness.
<u>Explanation;</u>
- Dizziness happens after a tiresome activity done continuously for a period of time thus one should get up slowly and gradually to avoid other injuries like falling endangering the life of the unborn child.
