Answers
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.

Pleaseeee help!!! (psychology edge) Androgens and estrogens are hormones that impact the sexual response cycle. Write about the four phases of that cycle and explain how the two types of hormones are involved.
Answers
Answer:
Females and males each have some amount of the sex hormones, androgens and estrogens. In males however, androgens like testosterone is more dominant and in females estrogens like estradiol are more dominant. The hormones both affect the sexual response cycle. The sexual response cycle has four phases: desire, arousal, orgasm and resolution. The desire phase can last anywhere from a few minutes to hours and includes physical changes like an increase in muscle tension, heartbeats quickening, flushed skin, and an increased flow of blood to genitals. The arousal phase extends to the brink of the orgasm phase, during this phase the changes experienced in the desire phase are intensified along with blood pressure increasing. The orgasm phase generally only lasts a few seconds and is the climax of the sexual response cycle, some characteristics include: Involuntary muscle contractions and spasms, blood pressure, breathing, and heart rate at their highest point, a release of built up sexual tension, and flushed skin. During the resolution phase the body returns to normal, often a sense of wellbeing and fatigue is achieved. To begin the cycle a male need a certain amount of the androgen, testosterone, but high levels in females tend to lead to more sexual thought and desires, typically though, women have relatively low levels of testosterone. In women, estrogens, such as estradiol are more common. Estrogens are produced when a girl starts puberty and helps her reproductive cycle begin. A high level of estrogen in men can lead to a reduced sex drive, loss of hair, or trouble focusing, but a normal level in men is crucial to proper erectile function.

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
Answers
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.

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)
Answers
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.

Explanation:
easch couplet presents the user with 2 alternatives and exclusive sets of character's.
10 couplets should your key have. If you are building a dichotomous key, and you have 10 species to identify. Hence, option D is correct.
What is dichotomous key?A dichotomous key, a crucial piece of scientific gear, is used to discriminate between diverse species according to their visible traits. Users must choose one of two possibilities to answer a series of questions that make up dichotomous keys.
A dichotomous key in the identification of trees, for instance, would ask whether the tree has leaves or needles. The key then leads the user down one set of questions if the tree has leaves; if the tree has needles, a different set of questions is shown.
The three most prevalent types of dichotomous keys are nested, connected, and branched. Each sentence has the appropriate response written next to it in nested type.
Thus, option D is correct.

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.
Answers
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
Answers
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.
