Why do identical twins separated at birth show DIFFERENCES as seen in the pictures?

A. Their DNA changed because of the different environments they lived in.

B. Different genes were turned on or off because of he different environments they lived in.

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.

Answer:

Eukaryotic cells have a membrane-bound nucleus.

Prokaryotic cells do not. The nucleus is where Eukaryotic stores their genetic information.

2

Explanation:

Though the effect of ships disappearing over the horizon is due to its spherical shape, it could also be used evidence for objects falling off the "edge" of a flat, planar-shaped earth.

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

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.

Answer:

Hi friend..are we still on for tonight?

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.

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.

Answer:

Minimise water usage

Weather doesn't affect the crops

Explanation:

Answer:

Oceans

The oceans are a massive carbon sink, and part of the positive reinforcement of the greenhouse gas cycle is that, as the oceans become warmer, then tend to release more carbon dioxide dissolved in the water which in turn drives temperatures warmer.

Answer:

Utility: The Nguni cattle are used for milk and meat; their socio-cultural functions are also important. The body conformation of the Nguni is more of a dairy than beef type but it is principally used for beef production and for work.
