Explanation:
The box’s measurements are: length = 50 cm, width = 25 cm, and height = 25 cm. The measurements of the block are: length = 10 cm, width = 10 cm, and height is 5 cm.
Out of 100 marble drops or shots, the marble hit the block 32 times.
volume of the box = 50 × 25 × 25 = 31250 cm 3
volume of the block = 10 × 10 × 5 = 500 cm 3
Ratio = 500/31250 = 0.016 × 100 = 1.6%
The volume of the block is 1.6% of the volume of the box
Ratio = 32 hits/100 shots = 0.32 × 100 = 32%
The block was hit 32% of the time.
Percentages will be similar and both be small percentages

Describe the similarities between enzymes and receptors.
Answer:
Receptors and enzymes are both located in the cell membrane. Receptors and enzymes are both proteins that can cause a reaction or response. Receptors and enzymes both speed up chemical reactions. Receptors and enzymes do not have any similarities.
Explanation:
Enzymes are known as biological catalysts. They speed up a chemical reaction taking place inside the body. Receptors can be defined as the chemical structures that transduce and receive signals.
The similarities between enzymes and receptors are as follows:
Both are composed of proteins.Both contain specified sites for their substrates.Receptor causes a response and enzymes facilitates a reaction.Both are proteins and both are crucial for the completion of different functions in the body.

What causes cells to become specialized??? ✨
Answer:
Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.

PLEASE HELP :) What is the difference between Gross Primary Production and Net primary production in simple terms? (If you could also provide an example I would really appreciate it.) Thank you for your time!
Answer:
Gross primary production (GPP) is the total rate at which material is produced and net primary production (NPP) is the rate at which material is accumulated in excess of respiration. In other words, NPP is GPP minus respiration. ... Net primary production is directly related to ecosystem conditions.

If you poured the fluids below into a container, which would sink to the bottom?
-water with a density of 1.0 g/cm3
-vegetable oil with a density of 0.91 g/cm3
-honey with a density of 1.36 g/cm3
-air with a density of 0.00013 g/cm3
Answer:
Honey > Water > oil > air
Explanation:
Heavy density will sink and less heavy density will float
So,
Density of honey is highest so, honey will sink
than,
Density of water is higher so, vegetable oil will float
Density of oil is higher so, air will float
Honey > Water > oil > air
Which type of energy transformation is controlled by chloroplasts?
Why did the narrator use the phrase "fit together like puzzle pieces" to describe how the cells of a developing human
embryo form a human face?
Answer:
The narrator uses that phrase because the pieces of the skin and face feathers have to come together as one to create a human head so they would be fitting together like puzzle pieces.
Explanation:
Answer:
The human face doesn’t form all at once. It requires many divisions of cells. As the cells divide, they eventually piece together to form a human face.

a student needs to find the density of a cube. each side of the cube measures 3 cm and the mass of the cube is 12g. what is the approximate density of the cube?
A. 0.4g/cm3
B. 2.25g/cm3
C. 4.0g/cm3
D. 36g/cm3
Answer:
Density = 0.4g/cm³
Explanation:
Given
Mass = 12 g
Length = 3 cm
Required
Determine the density.
To calculate density, we need volume.
Volume of a cube is:
Volume = Length ³
Hence:
Volume = (3cm)³
Volume = 27cm³
Density = Mass/Volume
Density = 12/27
Density = 0.4g/cm³ --- Approximated

This organelle modifies and labels proteins so they will be working properly and arrive at the correct destinations? so whats the answer?
Answer:
[tex]\boxed {\tt Golgi \ apparatus}[/tex]
Explanation:
After a protein is produced on a ribosome it is sent to the endoplasmic reticulum. Here, proteins fold and then are sent to the golgi apparatus.
In this organelle, proteins are modified and labeled. Sugar groups (modifications ) and tags/signals (labels) can be added. From the golgi apparatus they are sent to different destinations or secreted.
So, the correct answer is Golgi apparatus.
Golgi apparatus
The Golgi apparatus, which is usually situated near the nucleus, receives proteins and lipids from the ER, modifies them, and then dispatches them to other destinations in the cell. Transport from the ER to the Golgi apparatus—and the Golgi can either move onward through the Golgi stack or, if they contain an ER retention signal, be returned to the ER; proteins exiting from the Golgi are sorted according to whether they are destined for lysosomes (via endosomes) or for the cell surface.

Which would best allow a species to survive environmental changes? (8.L.4.2)
similar physical
features
low mutation rate
genetic diversity
small population
Small population is the answer
Your welcome
According to the Charles darwin theory of natural selection, genetic diversity best allow a species to survive environmental changes.
What is the theory of natural selection?Natural selection is the procedure via which populations of living organisms acclimate and modify.
Individuals in a population are naturally variable, indicating that they are all distinct in some manner. This divergence means that some individuals have characteristics better suited to the environment than others.
Natural selection leads to evolution.
Thus, genetic diversity best allow a species to survive environmental changes.

Where does the water enter the plant in photosynthesis?
Answer:
The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. The roots have a type of cell called a root hair cell. These project out from the root into the soil, and have a big surface area and thin walls. This lets water pass into them easily.

Under certain external conditions, a person will perspire a great deal. For which internal condition does this response
primarily provide homeostasis?
water balance
electrolyte balance
temperature balance
energy balance
Answer:
Perspiration provides homeostasis to the internal condition of temperature balance.
Explanation:
Perspiration occurs as a consequence of the increase in environmental temperature, which at the same time produces an increase in body temperature.
The high body temperature produces a stimulus that reaches the thermoregulation center of the central nervous system, which produces a response transmitted through the sympathetic nervous system, causing the sweat glands to increase the production of sweat.
The sweat that covers the skin is capable of acting as a physical agent to lower the temperature, a mechanism of thermal regulation that contributes to temperature balance.
The other options are not correct because:
Water and electrolyte balance is done at the renal level. The energy balance depends on the food intake and the amount of energy used.Answer:
temperature balance

In what type of climate do trees produce narrower rings?
cool and dry
warm and wet
cool and wet
warm and dry
Answer:
Cool and dry
Explanation: Trees tend to be sensitive to climates, so when the conditions are good the trees grows faster which results in wider growth rings and in poor conditions the tree grows slower which results in it laying down less tissue and therefore a narrower ring size. Drought and a blizzard can also cause narrower ring too. Actually, a cool way to find out if the climate conditions were good is to measure the rings of a tree every month each year. If the rings were consistently the same then you know the climate stayed pretty much the same and etc.
