The arrows in a food chain show: a Who eats who b Heat energy being lost c The movement of energy between organisms d The route of food to the shops
Answer:
c The movement of energy between organisms
Explanation:
Pyramid of energy is a model used to depict the flow of energy from one trophic level or feeding level to the next in an ecosystem. It's a diagram that compares the energy used by organisms at each trophic level of the food chain. The pyramid of energy must never be inverted or turned upside down.
The units used in the construction of pyramids of energy is kilocalories (kcal) or energy per area per time (Jm-²year-¹).
This ultimately implies that, the arrows in a food chain show the movement of energy between organisms such as from producers which are autotrophs or self-feeders such as plants to the tertiary consumers.
Furthermore, a list of the types of organisms in an eco pyramid are;
I. Producers: these are autotrophs or self-feeders such as plants.
II. Primary consumers: these are herbivores that typically feed on plants such as a goat or deer.
III. Secondary consumers: these consists of carnivores that typically feed or eat flesh such as lion, tiger, cheetah, etc.
IV. Tertiary consumers: these are higher predators such as humans that aren't normally fed on by other organisms in the ecosystem.
Answer: The arrows in a food chain show (The movement of energy between organisms). The correct option is C.
Explanation:
In an ecosystem, a food chain shows the transfer of energy and nutrients ( food) from organisms to organisms in a feeding pathway. Instead of giving functional group names such as primary producer, primary consumer and so on, in a good chain, the organism at each step is identified. Thus,
Grass-------> Zebra ---------> lion
(Primary (Primary ( secondary
producer). consumer) consumer)
this is an example of a simple food chain in a grassland ecosystem. This ARROWS represented above shows the direction of energy flow through an ecosystem.
Furthermore, the grass traps solar energy and stores it as chemical energy in the food made during photosynthesis. When eaten by Zebra, which is the primary consumer, the energy stored in the grass is transferred to the consumer. This transfer is inefficient as some of the stored chemical energy is lost as heat. When the zebra is eaten by a Lion,which is the secondary consumer.
The acceleration of an object is measure by its change in velocity per unit time. The equation for acceleration is: a =v/t. Acceleration is represented by 'a'. Velocity is represented by 'v'. Time is represented by 't'. Rearrange the equation to solve for time.
Answer:
t=v/a
Explanation:
To solve for Time
Since acceleration is change in velocity/time
a=v/t
Cross multiply
a×t=v
at=v
Divide both side by a since we want to find Time
at/a=v/a
t= v/a
3) In order for an ecosystem to thrive, it needs to exist in a form of harmony and balance between its biotic and abiotic factors. Describe how small changes to both biotic and abiotic components can have major effects on an ecosystem.
Answer:
Changing temperature causes extinction or removal of organism from that place.
Explanation:
Small changes to both biotic and abiotic components can have major effects on an ecosystem because these are the factors on which the ecosystem depends. For example, if the temperature of the ecosystem increases from its limit, it makes the environment unfavourable for the organism so due to this change, the organism migrated to other location otherwise they will die due to unfavourable environment.
Proteins secreted by Gram-negative cells face multiple obstacles, including _____. Multiple choice question. moving across the periplasmic space underlying the thick peptidoglycan layer of the cell wall moving across the plasma membrane moving across the plasma membrane and the thick peptidoglycan layer of the cell wall moving across both the plasma membrane and the outer membrane
Answer:
moving across both the plasma membrane and the outer membrane
Explanation:
Gram-negative bacteria are bacteria that have a plasma membrane, a thin peptidoglycan layer, and an outer membrane (the space between the plasma membrane and the outer membrane is known as periplasm). Moreover, Gram-positive bacteria exhibit neither outer membrane nor periplasmic space and are surrounded by thick layers of peptidoglycan. Gram-negative bacteria have developed different protein secretion systems (types I–VI and type VIII) in order to secrete proteins into the extracellular space. For such purpose, the XcpQ protein (which is an outer membrane protein from the secretin family) participates in different transport processes in Gram-negative bacteria.

HELP ME PLEASEEEE:(((
Answer:
C. Red
Explanation:
Red colour on the map shows the Mid Atlantic Ridge. The Mid-Atlantic Ridge is also called as a mid-ocean ridge. It is an underwater mountain system formed due to plate tectonics. It is created due to a divergent plate boundary that started from 87° N about 333 km to the south of the North Pole which is 54 °S, which is north of the coast of Antarctica. In the picture, the red colour is the line that shows Mid Atlantic Ridge.

Why are enzymes important?
1. They contain the genetic material.
2. They speed up chemical reactions.
3. They bring water into the cell.
4. They help the cell maintain its shape.
Why do you think genetic orders do not completely disappear from the human population, even though there are great researchers and excellent health care? PLS HELP
Answer:
Because we have not yet figured out to successfully remove/change genes on a large scale. Once we do, genetic disorders will no longer be as prevalent.
Explanation:
Braintliest please.
Which of the following does NOT affect the flow of groundwater through an aquifer ? a. porosity C. gradient b . chemical weatheringd. permeability
Answer:
b . chemical weathering
Explanation:
Chemical weathering is not affected the flow of groundwater through an aquifer but affect by the porosity and permeability. The rate of groundwater flow is controlled by two properties of the rock which are porosity and permeability. Porosity is the percentage of void space in a rock while on the other hand, Permeability is the quality of being permeable means able to be penetrated or passed through by a liquid or gas.

A. The same genes are expressed because of their environment.
B. Different genes are expressed due to their environment.
C. Their DNA is different.
Answer:
B. Different genes are expressed due to their environment.
Explanation:
I think it's this one because it makes the most sense, but I'm still not sure sorry
Answer:
B. Different genes are expressed due to their environment.
Explanation:
Some identical twins can have different heights and weights. This is because height and weight are controlled by what you eat as well your DNA. Differences in diet can start earlier than you might imagine. When the twins are growing inside the uterus, there can be differences in how well they connect to the placenta.

What is the microscopic nature of a cell ?
Why nucleus is said to be the controller of cellular activities ?
How is a cell adapted to its small size?
Answer:
No 1 answer They require sophiscated tools. The microscopes help in the study of cells. The molecular study of the cells are performed by the help of electron microscope. So, we can say that cells are microscopic in nature.
Explanation:
No 2 answer The nucleus is the largest and most prominent of a cell's organelles (Figure 3.7). The nucleus is generally considered the control center of the cell because it stores all of the genetic instructions for manufacturing proteins.
No 3 answer Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.

A.adaptive radiation
B.coevolution
C.mass extinction
D.punctuated equilibrium
Answer:
A
Explanation:
In evolutionary biology, adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available, alters biotic interactions or opens new environmental niches.
