Explanation:
they had to adapt to be able to survive to the new environment survival of the fittest
The correct answer A
This is in part due to carbon's ability to readily form bonds with other atoms, giving flexibility to the form and function that biomolecules can take, such as DNA and RNA, which are essential for the defining characteristics of life
If a woman takes HIV medicines during pregnancy and childbirth and her baby receives HIV medicines for 4 to 6 weeks after birth, the risk of transmitting HIV can be lowered to 2% or less. Most HIV medicines are safe to use during pregnancy, and don't increase the risk of birth defects.
In general, the infected mother should simply stay healthy and intake HIV medicines while she is pregnant.
Answer:
Three factors that affect my daily food choices include:
1. Taste
2. Length of time for preparation
3. Method of preparation.
Explanation:
When making choices for food, I tend to take several factors into consideration. Some of these factors include;
1. The taste of the food: If the food tastes good and is not too spicy I am more inclined to choose such food.
2. Length of time for preparation: Especially on stressful days, I tend to consider the length of time required to prepare a healthy meal. If it takes so much time I am more inclined to eat fast food which is not a good choice.
- To change this negative outcome, I hope to plan my affairs for the day and prepare healthy meals beforehand, which could be stored in the refrigerator and reheated when I need it.
3. Method of Preparation: Some foods require paying attention to details. For example, food that uses up, a lot of vegetables would require thorough washing to prevent particles in the food. Busy days also get me exhausted with no strength to pay attention to these protocols.
- To turn this around, I hope to employ the help of a family member to make the process easier.
- I also hope to process most of my ingredients and keep them ready for use so that I would not have to do a lot of processing while cooking.
(1) volume is given by
Volume=length*width*height=10cm*5cm*3cm=150 cm^3
(2) Density = mass/volume = 180 g / 150 cm^3 = (180/150) g / cm^3 = 1.2 g / cm^3
(3) Mass is independent of gravity, so the solid will have the same mass on the moon, on mars or any other planet.
Weight is the product of mass and acceleration due to gravity. Acceleration due to gravity on earth is 9.8 m/s^2, while on the moon, it is 1.62 m/s^2. Therefore the solid has a different weight on the moon than that on earth.
(4) If an object sinks in (pure) water, the density must be greater than one, since (pure) water has a density of exactly.1.0.
(5) Not all solid with he same dimensions have the same density, which depends on the nature of the material. Wood is lighter than water, while iron has a density of 7.8, gold has a density of 19.3, etc. However, all objects having the same dimensions have the same VOLUME.
(6) SI (Système International) is a unit based on metre, kilogram and second for length, mass and time measurements.
(7) Remaining definitions can be looked up in your textbook. If you need further definitions, please post.
