Use the picture to explain how CONVECTION heat transfers could be responsible for the weather in our atmosphere.
Answer the question in 2-3 complete sentences.
Answer:
The sun's waves heat the ground, causing it to warm (radiation). The energy flows from the warmer ground to the cooler air (conduction), causing it to rise (convection). When the rising air reaches a certain point, it expands, cools, and the cooler expanded air can no longer hold as much water vapor so it rains.

Suppose if all the bones of the skull (facial bones) are fused together, which function would you not be able to carry out?
Answer:
to masticate food
Explanation:
In adults, all the bones of the skull, except one, are fused together by immovable joints referred to as sutures. The sutures are fibrous joints which hold the bones of the skull together to form a rigid and strong structure that protects the brain. Skull bones fuse around two-years (18 to 24 months after birth). The only skull bone that is not fused by sutures in adults is the mandible, which is used to masticate food.

In the female human reproductive system, eggs are created in an ovary, and implanted in the uterus. For the embryo to grow, it must receive nutrients and oxygen. This problem is solved through an organ called the A. Amniotic sac B. Placenta C. Uterus D. Umbilical cord
Answer:
The correct answer is D. Umbilical cord
Explanation:
The umbilical cord connects the fetus to the placenta and through it exchanges nutritional substances as well as oxygen-rich blood. The umbilical cord is maintained throughout gestation until the moment of birth, when it is cut and leaves a permanent scar, the navel. The umbilical cord is responsible for breathing and feeding the fetus until the moment it is born, so any failure or blockage in the circulation of oxygen and nutrients through the cord can lead to injury or even death of the embryo. It also serves to remove waste and carbon dioxide (CO2).

How does the operator region of DNA work to regulate gene expression?
Answer:
Explanation:
Operator region are region of DNA (deoxyribonucliec acid) that repressors protein binds to prevent transcription.
Repressor is an example of regulatory protein they regulate the rate at which transcription of operon occurs . A repressor functions when its bounded to the operator and it prevent enzyme RNA (ribonucliec acid)polymerase from moving to DNA to transcribe the nitrogenous bases by placing a complementary base pair.
Activators are other regulatory proteins that bounds to its DNA binding site and increases transcription of the operon.

C. Fires are beneficial to the growth of many species.
Explanation:
Got it on study island
The forest fires impact the long term growth of plants and animals because the fire always cause species to become extinct. That is option D.
The effects of forest fires on speciesForest fire is an uncontrolled burning of plants in a natural habitat such as forest, grassland or bushes. This can be caused by:
Nature such as lightning strike,products of technology defects, or by unintentional negligence.The effect of fire on plants is a reduction in the vegetation density which inturn affect the food, water, and shelter of animals species.
Therefore the long term of uncontrolled burning of forest can lead to extinction of species that makes up that habitat.

B: energy pyramid
C: ecosystem
D: niche
Energy plays a important role in the propagation of life in ecosystems. Food chain shows the amount of energy that moves from one feeding level to another in a food web. Thus, the correct option is A.
What is food chain?A food chain is defined as the order of events in an ecosystem, where one living organism eats another organism, and later that organism is consumed by another larger organism.
The flow of nutrients and energy from one organism to another at different trophic levels forms a food chain. A system of interlocking food chains is called a food web.
