Answers
Answer:not you cheating on the bsa but she doesn’t have a control group
Explanation:
A dependent variable is missing in her experiment. Therefore, the correct option is option C among all the given options.
What is experiment?The scientific method is a methodical approach to learning about the world around you, and the experiment is its cornerstone. Even while some experiments are conducted in labs, you may conduct an experiment anytime, anyplace.
You contrast an intervention design with only a control group in a controlled experiment. With the exception of the independent variable, these two groups should be identical. Christina wanted to know whether the eating behavior of goldfish is affected by music. She set up a fish tank. Every day, she played music for the fish an measured how much the fish ate.

Suppose you are determining the growth rate of two species of plants. Species A is 25 cm tall and grows 3 cm per month. Species B is 10 cm tall and grows 8 cm per month. Which system of equations models the height of each species H(d) as a function of days d. H(d) = 25 + 3d H(d) = 10 + 8d H(d) = 3 + 25d H(d) = 8 + 10d H(d) = 25 + 3d H(d) = 8 + 10d H(d) = 2 + 8d H(d) = 25 + 10d
Answers
Answer:
H(A) = 25 + 3m and H(B) = 10 + 8m
Explanation:
Let H(A) is the height of species A as a function of months m while H(B) is height of species B as a function of months m.
For Species A,
H(A) = 25 + 3m
For species B,
H(B) = 10 + 8m
Hence, this is the required solution.
Mr. Shepherd is at a football game on a cold day. How does his body maintain a relatively constant body temperature? What is this process called?
Answers
Answer:
1. Mr. Shepherd maintain a relative constant body temperature by preventing loss of heat.
2 This process is called HOMEOSTASIS
Explanation:
Homeostasis is the process whereby living organisms maintain a stable internal environment despite changes in conditions to the external environment. It is necessary that the body undergoes this process in order to guarantee survival.
According to this question, Mr. Shepherd is at a football game on a cold day. This means that in order to maintain a stable internal temperature, the body must preserve heat in the body and prevent its loss via sweating.
The regulation of body temperature is maintain fundamentally by the thermoregulatory center located in the preoptic region of the hypothalamus, this process is called homeostasis, which is the balance that occurs in the internal environment.
The main thermoregulatory mechanism is the increase or decrease in blood flow to the skin, through vasodilation and vasoconstriction.
Thermal sensing cells or thermal sensors for heat and cold are located on the skin surface (peripheral receptors), in the pre-optic region of the anterior hypothalamus (central receptors) and in other parts of the body.When it is hot, blood circulation to the skin increases (it becomes red) and when it is cold it decreases (the skin becomes paler).In addition to blood flow, the body also uses sweat to regulate temperature, sweating evaporates water on the surface of the skin and heat is lost, thereby lowering body temperature.Therefore, we can conclude that the maintenance of body temperature is closely related to another important indicator, the internal environment (homeostasis).

The number of penguins can be used to monitor changes in temperature of the environment. Temperature readings could also be taken using a thermometer. What is the advantage of using penguins, instead of a thermometer, to monitor changes in temperature of the environment?
Answers
Answer:
Living organisms show long-term changes
Explanation:
The changes in climatic conditions can be evidenced by monitoring populations of wild species which are forced to adapt to survive. Penguin populations can help us not only to monitor but also to predict climatic fluctuations (e.g., temperature changes associated with Antarctic warming) in a whole context. Fluctuations in penguin populations in the Antarctic region show structural changes in the food chain, thereby population monitoring provides a means of assessing climate change as a whole, in the long term.

B. Transports the medium
C. Travels with a vacuum
D. Carries Solids
Answers
Answer:
A?
Explanation:
All waves carry energy from one location to another, but they do not move any physical objects. The energy is transferred from one particle to the next, which then oscillates as well. Thus, option A is correct.
What is the energy transport property of wave?The vibration of particles, which transfers energy in waves, causes the particles to travel perpendicular to the wave's horizontal movement. As the particles transition from rest to movement and back to rest, energy is changed between potential (stored) and kinetic (moving) energy.
However, waves do not move mass. By colliding with one another and exchanging energy, the particles “participate” in the wave. Because of this, energy can be transferred even when the particles' average positions remain unchanged.
Therefore, The thing that makes a wave is that it transport energy from one place to another.

Bacteria are responsible for carrying out
the process of nitrification. How are
bacteria classified?
A. Detritivores
B. Decomposers
C. Scavengers
D. Producers
Answers
Answer:
D
Explanation:
Hope this helps!!!!
Nitrification is a process that is carried out by a distinct group of bacteria that convert, which later adds it into soil hence decomposers.
A small group of aerobic bacteria makes use of the inorganic components. These microscopic organisms play a crucial role in the formation of soil and help in nitrogen fixation.
These bacteria convert the soil ammonia to nitrates and then dilute them into soil that otherwise would be toxic for the plants. As they convert the freely available nitrogen they are thus known as decomposers. Such as nitro-bacteria, nitro-spina.Hence they are classified as decomposers. Thus option B is correct.

Kendra wonders what would happen if the oceans did not exist on Earth. Based on her understanding of the oceans and the water cycle she predicts that Earth would become warmer, with less rain, more clouds, and that living things would not survive. Which part of her prediction is incorrect?
Answers
Answer: More clouds
Explanation:
Just like Kendra's prediction, if oceans did not exist, the Earth would become warmer with less rain and living things would not survive.
The prediction that there would be more clouds is wrong. Clouds are formed when water vapor in the air turns into ice crystals or liquid water droplets. It usually happens when the air contains more water vapor than it can hold.
And we know that oceans are the major sources of water on earth as they make up 70% of the earth's surface. So if oceans did not exist, other smaller bodies of water will cease to exist too within a short period of time because they would not be able to cater for the whole earth. Therefore, there would not be enough water to accumulate in the air to aid cloud formation.
Answer:Just like Kendra's prediction, if oceans did not exist, the Earth would become warmer with less rain and living things would not survive.
Explanation: That living things would not survive
