Answer:

Carbon Dioxide(CO2)

Explanation:

Plants undergo a process called photosynthesis. This is carried out by plants in the manufacture of their food such as sugar. The plants trap sunlight through a green coloring matter called chlorophyll and then uses Carbon Dioxide from the atmosphere and Water in the manufacture of Sugar.

6CO2+ 6H2O= C6H12O6+6O2

Answer:

<h2>Carbon Dioxide</h2>

Explanation:

Very Good Question

Plants absorb carbon dioxide from the atmosphere during photosynthesis . A small amount of carbon dioxide is released during leaf respiration , but it is quickly reabsorbed during photosynthesis.

(c) Based on the data in Table 1, describe why the dominant alleles for body color and wing shape are the alleles that produce a

Brrunno [24]

Answer:

Check the explanation

Explanation:

Consider the below table of F2 data of phenotypic flies: we can reconstruct the table as seen in the second attached image below:

From the above observations it is clear the Gray body long wings and Ebony body vestigial wings are the parental combinations and that the Gray body vestigial wings and Ebony body long wings are the recombinants.

Also the ratio indicates that Gray body is dominant over ebony body and that long wings is dominant over vestigial wings.

here the genes for the two characters have shown independent assortment which means that the genes are unlinked if located on the same chromosome or are located on different chromosomes.

Now F1 hybrid= GgLl (G for Grey and L for Long)

Cross between F1 hybrid and true breeding Gray vestigial (GGll)

GgLl x GG ll

Gametes-----------> GL Gl gL gl Gl

GL Gl gL gl

Gl GGLl GGll GgLl Ggll

(Gray long) (Gray vestigial) (gray Long) (Gray vestigial)

Therefore the probability of getting the flies with gray body vestigial wings= 2/4= 50%

b) The reason why the students obtained the above given F2 results involving a cross between true breeding Gray body and long wings with true breeding Ebony body and vestigial wings is that the genes for the two charcters asssort independently in F2 generation and that the genes are not linked as:

Parents------------------> GGLL x ggll

Gametes -----------------> GL gl

F1---------------------> GgLl (Gray long but in heterozous condition)

Now GgLl x GgLl

Gametes GL Gl gL gl GL Gl gL gl

Here gametes assorted independently and hence in F2 generation we got the above results (U can show the results in the form of punnett square.

Over the last few decades, scientists have noticed that lobsters, which obtain heat from the environment rather than generating

Setler79 [48]

Answer:

Lobsters are adapting to cooler temperatures.

Explanation:

Adaptation may be defined as the phenomena that involves the physical, physiological and chemical changes in the organisms that helps to adapt themselves in their environmental condition.

The adaptation may bring genetic changes in the next generation as well. The lobsters movement per year demonstrates that they are trying to adapt in their environment. The cooler temperatures is favorable for the growth and adaptation of Lobsters.

Thus, the answer is Lobsters are adapting to cooler temperatures.

Could producers survive without consumers? explain why or why not

arlik [135]

Producers could not survive without consumers. Produces rely on consumers to purchase their product, if no one buy their product, then the producer has no money to even produce anything. This like a car, the car is the producer, and the gas is the consumer, the car will not work unless there is gas. So a producer will not survive without the consumer.

The sea snails in tidal marine areas feed on the dominant species of algae. What kind of interaction takes place between the sea

jasenka [17]

Sea snails help to keep the algae's population from growing to high. And the algae provides the sea snails with energy from the snails eating it as a food source.
