Answers
Answer:
The answer is C.
Explanation:
This is because the objects will exchange thermal energy, until thermal equilibrium is reached, i.e. until their temperatures are equal. We say that heat flows from the hotter to the cooler object.
Energy is transferred from a warmer to a cooler object through the phenomenon of heat. For instance, a large pan of lukewarm water will gain heat from a lit match (a higher temperature object) (lower temperature object). Thus, option C is correct.
What change in temperature when object are in contact?It feels warmer in your hands to hold a hot cup. The heat is moving from one object to another, which is what you are feeling. Your hands receive the hot chocolate's thermal energy.
Heat is exchanged when two objects are at different temperatures. Up until the two items are at the same temperature, the cooler object warms up. Always, heat energy moves from a hot object to a cooler one.
The colder end will get energy from the hot end as it passes through the rod. The temperature will eventually equalize across the entire rod. Wearing gloves is crucial when working with hot metal, for this reason.
Therefore, The warmer object transfer heat energy to the cooler object.

what are sex hormones?why are they named so? state their function.
Answers
Answer:
Sex hormones or hormones of the reproductive organs are certain cells in the reproductive organs that produce hormones.
The testis produces testosterone,the male sex hormone,and the ovaries produces oestrogen and progesterone, the female sex hormones.
In a sexually mature male,testosterone influences sexual behaviour, and together with FSH,regulates sperm production in the seminiferous tubules of the testes.
Sexually matured females undergo a regular 4-week reproductive or menstrual cycle during which a mature egg is released.This cycle is regulated by oestrogen and progesterone. During pregnancy, progesterone inhibits egg production (ovulation),brings about the development of the placenta and prevents the uterus from contracting....I hope this answers your question...

Differentiate between sub-cellular and acellular particles with examples
Answers
Answer:
Explanation:
Sub-cellular particles are particles smaller than the living cell and are found suspended in the cytosol (of a cell) like the nucleus, golgi complex and the mitochondria.
While acellular particles/organisms are particles that do not have a cell like the virsues, viroids and prions. They are not alive/inactive outside a living environment but become active immediately they are inside a living environment (like a cell).
Sub-cellular particles are structures that are found within a cell. These structures perform specific functions and are essential for the cell to carry out its biological processes.
Examples of sub-cellular particles include organelles such as the nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus, and lysosomes. These structures are composed of both proteins and lipids and are enclosed by a membrane.
Acellular particles, on the other hand, are particles that do not possess a cellular structure and are not alive. These particles are much smaller than cells and are unable to carry out any metabolic processes.
Examples of acellular particles include viruses, prions, and viroids. These particles are composed of either DNA or RNA and can replicate themselves only within a host cell. They do not have their own metabolism and rely on the host cell for replication and survival.

Independent variable: _______ Dependent variable: _______ If the amount of milk a person drinks increases, the strength of his or her bones will stay the same. Independent variable: _______ Dependent variable: _______
Answers
Complete Question:
Part A: Identifying Variables
Read the following hypotheses and identify the variables.
If the number of cigarettes smoked increases, then the risk for lung cancer increases.
Independent variable: _______
Dependent variable: _______
If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase.
Independent variable: _______
Dependent variable: _______
If the amount of milk a person drinks increases, the strength of his or her bones will stay the same.
Independent variable: _______
Dependent variable: _______
Answer/Explanation:
Dependent variables are variables that is dependent on the independent variables. That is, it is the variable that changes as the independent variable changes.
Depedent variable is the main interest if a researcher. It is the variable that is measured in a research work.
In the above given hypotheses, the dependent and independent variables are shown below:
1. "risk for lung cancer" is dependent on the "number of cigarettes smoked".
"Risk for lung cancer" => dependent variable
Number of cigarettes => independent variable
2. "number of shark attacks on humans" is dependent on "number of sharks swimming".
Dependent variable => number of shark attacks on humans
Independent variable => number of sharks swimming
3. Dependent variable => strength of bone
Independent variable => amount of milk a person drinks
Answer:
Lab: Heart Rate
Part A: Identifying Variables
The dependent variable happens as a result of values/changes associated with the independent variable.
Independent variable: number of cigarettes smoked
Dependent variable: risk for lung cancer
Independent variable: number of sharks swimming in a coastal region
Dependent variable: number of shark attacks on humans
Independent variable: amount of milk a person drinks
Dependent variable: the strength of his or her bones
Part B: Heart Rate
Hypothesis: If I hold my breath for 30 seconds, then my heart rate will
(choose 1) increase/decrease.
Independent variable: holding my breath
Dependent variable: heart rate
Part C:
The heart rate decreases because oxygen exchange in the lungs decreases.
This depends on what you chose for heart rate in the hypothesis. If you said the heart rate decreases after holding your breath, and the results showed the heart rate decreased, then the hypothesis is supported. If you said the heart rate decreases after holding your breath, and the results showed the heart rate increased, then you refuted the hypothesis.
Heart rate can change due to an increase or decrease in activity, moving positions such as sitting and standing, and emotions.
Example: Increase in activity—jumping jacks
Hypothesis: If I do five jumping jacks, then my heart rate will increase.
Test hypothesis. You can use the average resting heart rate from the previous experiment. If you do an experiment with an increase in physical activity like jumping jacks, then your data will reflect an increase in heart rate because the body requires more energy, which requires more oxygen, increasing the overall flow of blood in the body.
Support or refute the hypothesis based on the results. The hypothesis is supported if it aligns with the observed results. The hypothesis is refuted if the results don’t match the statement based on the variables.
Testing more than one variable at a time makes it difficult to interpret the results and support or refute the hypothesis. With one variable, the results can be associated with changes to that variable. To get the most reliable data to support or refute a hypothesis, an experiment should be completed several times to see if the results show the same trends.

Explanation:
A Detritivore is a heterotrophic organism that feeds on dead plant and animal materials. They could also feed through coprophagy which is nutrition obtained by feeding on feces. Worms that dwell on the soil, insects, and mollusks are examples of detritivores. Detritivores can also be found residing in aquatic environments. Crabs and Lobsters are examples of these organisms.
Detritivores have no teeth. So, they tend to suck in their food, and this food, through peristaltic actions, moves directly into the digestive tract where it is acted upon by digestive enzymes. From the observations, I made about the organism at the mudflat at the ocean, I can conclude that it is a detritivore.

Explanation:
In order to determine whether you have hypoxia, your doctor will need to check the amount of oxygen in your blood. Therefore, option (C) is correct.
What do you mean by hypoxia?Hypoxia is low levels of oxygen in your body tissues. It causes symptoms like confusion, restlessness, difficulty breathing, rapid heart rate, and bluish skin.
Moreover, hypoxia is a state in which oxygen is not available in sufficient amounts at the tissue level to maintain adequate homeostasis; this can result from inadequate oxygen delivery to the tissues either due to low blood supply or low oxygen content in the blood (hypoxemia).
Hence, heart and lung function issues can lead to five categories of conditions that cause hypoxemia: ventilation-perfusion (V/Q) mismatch, diffusion impairment, hypoventilation, low environmental oxygen and right-to-left shunting.

Help? You are studying an outcrop where the lower layer is limestone and the layer directly on top of the limestone is sandstone. Near the bottom of the sandstone layer are small, weathered pieces of limestone entirely contained within the sandstone. Explain how these pieces of limestone came to be contained within the sandstone.
Answers
Answer:
Due to mixing of particles present in the upper layer of limestone with sandstone during deposition.
Explanation:
The parent layer was limestone layer which is older than sandstone layer. This sandstone layer spreads on the limestone layer because of wind. The wind moves these sandstone from other region and their deposition occurs on the limestone layer. During deposition of sandstone, some particles of limestone which are present at the surface mixes with the sandstone so that's why in sandstone layer, small and weathered pieces of limestone are present.
