What kind of features would you expect to find in a transitional
fossil between Ichthyostega and Eusthenopteron?
Answer:
hope that help you
Explanation:
Fossils or organisms that show the intermediate states between an ancestral form and that of its descendants are referred to as transitional forms. There are numerous examples of transitional forms in the fossil record, providing an abundance of evidence for change over time.
What are the two most important driving forces of metamorphism?
A. High heat and pressure
B. Melting and cystallization
C. Deposition and lithification
D.Weathering and accumulation
E.Magma and lava
ne questions
Answer:
Heat and pressure
Explanation:
Metamorphic rocks are found deep underground
The two most important driving forces of metamorphism are high heat and pressure (option A).
These two factors play a significant role in transforming rocks into metamorphic rocks. When rocks are subjected to high temperatures and pressures, the minerals within them undergo changes in their composition, structure, and texture. This process leads to the formation of new minerals and the recrystallization of existing minerals, resulting in the development of distinct metamorphic textures and structures.
The course of transformation doesn't dissolve the stones, however rather changes them into denser, more conservative rocks. Rearrangements of mineral components or reactions with fluids that enter the rocks produce new minerals.

Which of the following is a renewable source of energy?
O A. Solar energy
O B. Nuclear power
C. Coal
D. Natural gas
Answer: A. Solar energy
Explanation:
Hope this helps :)
Solar energy is the renewable source of energy. So, the correct option is A.
What is Renewable resources?A natural resource that can be replenished to replace the portion used up by usage and consumption is known as a renewable resource, furthermore known as a flow resource. This replenishment can occur naturally through reproduction or through other recurring processes in a limited amount of time on a human time scale.
Renewable energy is generated by renewable resources that replace themselves more quickly than they are used up. Examples of these sources that are continuously replenished are the sun and the wind.
Solar energy, wind, falling water, geothermal heat from the soil, biomass from plants, waves, ocean currents, temperature variations in the oceans, and tide energy are all examples of renewable resources.
Therefore, the correct option is A.

What is the name of the process that plant cells use chloroplast to create their own food?. Single choice.
access the capabilities of animal and plant cell types owing the presence or absence of chloroplast and cell wall
Answer:At this point, it should be clear that eukaryotic cells have a more complex structure than do prokaryotic cells. Organelles allow for various functions to occur in the cell at the same time. Despite their fundamental similarities, there are some striking differences between animal and plant cells (see Figure 1).
Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.

Which of the following best compares the functions of the ovaries and the uterus? (1 point)
Embryos are formed in the ovaries and zygotes are produced in the uterus during fertilization.
Zygotes are fertilized in the ovaries and develop into fetuses in the uterus.
Eggs are produced in the ovaries and zygotes implant in the uterus.
Eggs are fertilized in the ovaries and mature in the uterus.
Answer:
C. Eggs are produced in the ovaries and zygotes implant in the uterus.
Explanation:
The egg cells are formed in the Ovaries through the process of Ovulation. The sperm and the egg cell (ovum) fertilize together in the Fallopian Tubes or Oviducts. After fertilization, the zygote formed slowly moves to the uterus, and implants itself into the walls of the uterus. Then, it starts dividing itself into an embryo and later into a complete fetus.

A rock sitting on the surface of the Earth is pushed down deep into the Earth over time and is exposed to tremendous heat and pressure over time. Although the rock does not melt, it does change into a new type of rock. How would the new rock be classified? Igneous Igneous Magma Magma Metamorphic Metamorphic Sedimentary
Answer:Metamorphic
Explanation:
Sedimentary rock is from sand or gravel. Igneous rock is melted rock. Metamorphic rock is rock that has been exposed to high pressure and heat but did not melt
Metamorphism refers to the change in structure and mineral composition of rocks when exposed to extreme temperatures and pressure. The correct option is metamorphic rocks.
What are metamorphic rocks?
Metamorphic rocks are one of the three types of rocks, product of subduction events, melting and transformation.
What is metamorphism?
Metamorphism provokes several changes in an original preexisting rock concerning its structure and mineral composition. The main factors causing these changes are temperature and pressure.
These physic-chemical processes usually occur in deepness and are related to plates movement and subduction processes.
The rising sharped temperature might be caused by magma injection or by a deep placement of the original rock in a subduction zone.
Pressure generates alignment of materials (foliation and schistosity) and mineral rotation
According to the metamorphism processes, there are different kinds of metamorphic rocks.
The correct option is metamorphic rocks.

Antimycin A Antimycin A is used in catfish farming: added to the water at 10 ppb, it kills small fish but does not harm catfish. Thus, small fish die out, and catfish get all the resources. When Antimycin A is added to isolated mitochondria, NADH and succinate both accumulate. However, if ascorbate, an artificial redox mediator that transfers electrons to cytochrome c, is added, oxygen consumption is still observed. Which step in the respiratory chain is antimycin A likely to inhibit (1 pt)
Answer:
Inhibits electron transport chain in mitochondria.
Explanation:
Antimycin A inhibits electron transport chain which leads to the complete halt of electron transport in mitochondria. due to this inhibition of electron transport chain in mitochondria leads to the killing of the fishes except catfish and so the catfish increase in population due to more resources and no competition. this Antimycin A is highly toxic for fishes and kill all fishes if used at the amount of 10 ppb.

A television works by transforming electrical energy into what other kinds of energy?
a) light thermal and sound
b) thermal chemical and solar
c) sound mechanical and electrical
d) light chemical and mechanical
Answer: It is A
Explanation: It is A because the television gives off light and sometimes that could heat up the tv and it is sound because obviously television makes sounds because of the volume :) hopefully that helps.
Option A, which is light heat and sound, is the right response. Electrical energy is converted into different forms of energy by a television to operate. Thermal energy, sound, and light are produced using this energy.
What is the first step of the mechanism ?The power supply unit first changes electrical energy into alternating current (AC). The image tube, which has a vacuum and an electron gun, receives this AC after that. Electrical energy is transformed into thermal and optical energy by the electron cannon.
The thermal energy is subsequently lost while the light energy is focused onto the screen. The speakers produce the sound by transforming electrical energy into sound waves. The other choices are inaccurate because they do not adequately depict how a television converts energy.
Option B uses energy sources other than televisions, such as chemical and solar energy. The mechanical and electrical energy found in the television is included in Option C. Option D also uses chemical and mechanical energy, which a television cannot produce.
As a result, choice A is the right response.

what are the steps in the digestion of protein
Explanation:
Protein digestion begins when you first start chewing. There are two enzymes in your saliva called amylase and lipase. They mostly break down carbohydrates and fats. Once a protein source reaches your stomach, hydrochloric acid and enzymes called proteases break it down into smaller chains of amino acids.
