During a lab investigation a scientist heats a solid substance. The scientist observes that the solid has two different melting points. The scientist is able to separate the two resulting liquids. Which statement best classifies the original solid substance
Answer:
This question is incomplete; the options are:
A. It was an atom.
B. It was a mixture.
C. It was an element.
D. It was a compound.
The answer is B. It was a mixture.
Explanation:
A mixture is a substance which contains two or more different substances (with differing properties) that can be easily separated from each other. Each component of a mixture retains their individual properties, hence, they can be separated via physical means.
According to this question, a scientist is conducting an investigation where it was observed that the solid involved has two melting points. After heating the solid, the scientist is able to separate the two resulting liquids. This suggests that the original solid substance was a MIXTURE because it could be separate using heat.

2. What influence does the FBP1 protein have on the cell cycle and how can this proliferate the cancer
Answer:
FBP1 promotes cancer by accelerating the transition of cell cycle from G1 to S and G2 stages
Explanation:
The far-upstream element (Fuse)-binding protein 1(FBP1) is an oncoprotein that is overexpressed in different types of cancers such as, for example, hepatocellular carcinoma, ovarian cancer, etc. It is known that FBP1 binds to the tumor suppressor gene p53 and thus suppresses its transcription. Moreover, in ovarian cancer, it has been shown that the inactivation or 'knockdown' of FBP1 inhibits cell cycle transition from G1 (the first phase of the cell cycle during cell division) to S and G2 phase. The cyclin D1/E and c-Myc proteins which are required for the progression of cells through the cell cycle were found to be inhibited in FBP1-knockdown cells.

Why did the Rocky Planets form closer to the Sun than the Gas Giants?
Answer: High Temperatures from the sun
Explanation:
Due to the high temperatures radiating from the sun, only materials that had high melting points could survive around it as opposed to those with low melting points that became vaporized into gas. These materials with higher temperatures were then pulled by the gravity of the sun and kept colliding till they formed the inner planets closest to the sun being Mercury, Venus, Earth and Mars.
The other materials that were with low melting points which became gas spread to the outer part of the solar system and as they became ice, they came together and formed cores with gravities that pulled other gases till they formed the gas giants as we know them today.

1. A closer look - The food environment and food choices Some foods are nutrient-rich, while others are energy-rich yet nutrient-poor. Whole foods are the most nutrient dense because nutrients are left intact, which supports the best satiety cues (for example, an orange vs. orange juice), and overall confer the best outcome physiologically. Three-day diet records are often used to get an idea of an individual’s overall dietary habits to determine average daily caloric intake and how nutrient-rich the diet is. For the next three days, select the items that are richest in nutrients. Choose three items for each day’s lunch.
Answer:
Explanation:
Below is the diet of 3 days launch
Day 1:
Bacon
Peanut Butter (contains only peanuts) with bread
Day 2:
Plain Greek yogurt
Variety pack of Quaker instant oatmeal
Day 3:
Fruit on the bottom regular yogurt
Nature Valley granola bars
Since three day diet records can be used to assess an individual’s dietary habits, the food items consumed within this three days can then be thoroughly looked into to check the nutrient rich diet and the nutrient poor diet.
The nutrition rich diet should be maintained as they supply the body some important nutrients needed for its activities while the nutrients poor diet should be replaced with nutrient rich diet. Having fruits juice, yoghurt are good but can be supplement with whole food like cereals, vegetables, whole fruits for better body performance.
Important nutrients elements needed for the body should be checked and sought out from the daily intake when they are lacking diet containing such nutrient should be added.

Hope this helps
Pistil and stamen are the reproductive organs of the plant. Stomata and guard cells are responsible for the gaseous exchange in plants and the xylem and phloem are responsible for conduction in plants. Thus, the correct option is D.
What are the different parts of plant?The different parts of plant consist of roots, shoots, leaves, flowers. All these parts contain different tissues and cells which are responsible for a specific function in the plant body.
The pistil and stamen are the reproductive structures in the plant cell. Pistil is the female part where stamen is the male reproductive part which are responsible for the production of new plants.
Stomata and guard cells are the specialized cells which are present on the surface of leaves. These cells are responsible for the exchange of gases and transpiration of water through the surface of leaves of plants.
Xylem and phloem are the vascular tissues which are responsible for the conduction of water and minerals in the plant body. These are made up of different types of cells hence, are known as complex tissues.
Anther and stigma are the parts of the male and female gametophyte. Anther contains pollen which have the male gamete whereas stigma is the part of the female reproductive structure on which the pollens land by pollination for the fertilization of the flower to form zygote.

A 42-year-old male reports pain in his lower back for the past month. The pain sometimes radiates to his left leg. In determining the cause of the back pain, based on your knowledge of anatomy, what nerve roots might be involved
Answer:
Sciatic nerve.
Explanation:
The sciatic nerve is the longest and thickest in the anatomy and it originates from the sacral plexus. The sciatic nerve and its nerve branches allow movement and sensation (motor and sensory functions) in the thigh, knee, calf, ankle, feet, and fingers. When the pain exceeds the lumbar area and reaches the lower limbs, we speak of radiating lumbar pain. If the pain spreads from the lower back to the heel or foot, down the back or side of the thigh, we call it lumbosciatica (or just sciatica). Its presence suggests injury to the nerve roots that come out of the lumbar spine and carry the sensation or orders to contract the muscles to the lower limbs through the sciatic nerve.

Which two processes are most directly represented in this diagram?
ATP synthesis and the diffusion of water
molecule transport and energy use
homeostasis and ATP synthesis
homeostasis and the diffusion of water
Answer:
B) molecule transport and energy use
Explanation:
Glucose is being transported into the cell, and it requires energy. This is the only right answer, I know this from seeing my graded Cell Membrane quiz.
The transport of molecule and energy use are the two processes that is represented in the diagram.
The movement of glucose across a cell membrane represents the transportation of molecule to produce energy in the form of ATP molecules. Glucose is used in the mitochondria of the cell in order to produce energy in the form of ATP which is used by the cell in different activities carried out by the cell so we can conclude that the diagram shows us the transportation of molecules and energy use during this process.
