which are the catalysts of reactions in living things

Answers

Answer 1
Enzymes are proteins that act as biological catalysts. They speed up chemical reactions that take place in cells. Enzymes act by lowering the activation energies, which has a dramatic effect on how quickly reactions are completed.

Mecayla harvests oysters from the shallow waters of the marsh near her home. She eats the shellfish almost every day. Her brother Kendis dislikes oysters but eats local predator fish from the river three times a week. Recent water quality tests show moderate levels of heavy metals in the river and marsh. What is the most likely result of this pollutant on Mecayla and Kendis if they maintain the same diet?
Mecayla will get sick first because she eats oysters every day.
Kendis will get sick first because of less bioaccumulation.
Biomagnification will cause Kendis to become ill first.
Bioaccumulation will cause Mecayla to become ill first.

Answers

Answer: Biomagnification will cause Kendis to become ill first.

Explanation: This answer is correct because Kendis is eating the predator fish and Mecayla is only eating some oysters from the shallow water. Biomagnification causes the concentration of toxins, specifically in the predator fish, therefore Kendis will become ill first.

Mecayla harvests oysters from the shallow waters of the marsh near her home. Biomagnification will cause Kendis to become ill first.

What is the ocean?

The existence of life on our planet is due to the oceans. Today, more than 230,000 marine species call the sea their home. Life began in the water.

Climate and temperature on Earth are governed by the oceans. They regulate temperatures and play a critical role in precipitation formation. The world's five oceans have a salinity that is around 3.5 percent on average.

The Mediterranean, the Atlantic, and the Bay of Bengal, on the other hand, have higher saline levels.

Therefore, Mecayla harvests oysters from the shallow waters of the marsh near her home. Biomagnification will cause Kendis to become ill first.

Known as the 'Pine Tree State; Maine's state tree is the Eastern white pine. Consider the model. Cärbon dioxide, water, and sunlight
are reactants of photosynthesis and are used to produce glucose and release water as a byproduct. What advantage does the pine tree
have in performing photosynthesis compared to deciduous trees such as oak or maple?
34)
A) Pine trees need less water to do photosynthesis.
B) Pine trees produce twice as much glucose as deciduous trees.
C) Pine trees do not lose their leaves and can photosynthesize all year.
D) Pine trees get more sunlight than oak trees due to their darker color.

Answers

Answer:

C) Pine trees do not lose their leaves and can photosynthesize all year.

Explanation:

In cold-temperate and Arctic regions, however, evergreens are typically cone-bearing shrubs or trees (conifers), such as pines and firs. Many tropical species of broad-leaved blooming plants are evergreen. Thus, option C is correct.

What are features of pine trees?

Pine trees may photosynthesize in the winter because they retain their needles all year long! Compared to trees that lose their leaves, this is a significant advantage.

Their leaves therefore stay green and stay attached for a longer period of time than their deciduous counterparts because they can preserve more water.

However, because of their tiny surface area, needles are not as effective at absorbing the sun's energy.

Therefore, Pine trees do not lose their leaves and can photosynthesize all year.

Which statement is a hypothesis that would best address the question "Are rainbow trout eating all the macroinvertebrates in streams and starving out other fish species?" If rainbow trout are eating all the macroinvertebrates, then keeping rainbow trout out of new river habitats will allow native species to recover. If rainbow trout are eating all the macroinvertebrates, then introducing them to other streams will help native species recover. Rainbow trout will eat a variety of macroinvertebrates and native fish species. Rainbow trout hunt and prey upon native fish species.

Answers

A possible hypothesis here is; "If rainbow trout are eating all the macroinvertebrates, then keeping rainbow trout out of new river habitats will allow native species to recover."

A hypothesis is a statement that is tentatively put forward to explain an observation. Usually, a hypothesis is an if .... then statement. This is one of the first things that we must look out for when considering each of the statements.

Since we have observed that rainbow trout eating all the macroinvertebrates in streams and starving out other fish species, it follows that  keeping rainbow trout out of new river habitats will allow native species to recover."

in yeast that has been genetically modified to be able to produce spider silk, the ________ is joined with the ________ .

Answers

A transgenic organism is an organism whose genome (DNA) has been altered by recombinant genetic engineering techniques. These techniques can be used to transfer exogenous genes within transgenic species.

In yeast that has been genetically modified to be able to produce spider silk, the spider silk CODING SEQUENCE is joined with the yeast REGULATORY SEQUENCE.

In this case, transgenic yeast has the spider silk coding gene sequence (i.e., the exons) that encodes for the spider silk protein, whereas a regulatory gene sequence (e.g., a promoter gene sequence) from yeast have been preserved in order to regulate the expression of the target exogenous gene.

The most important genetic engineering techniques used to create transgenic animals include DNA microinjection and retrovirus-mediated gene transfer.
