__plants important adaptation of the seed allowed plants to__
A. Non vascular, grow in underwater environments
OB. Angiosperm, attract pollinators
C. None of these
D. Gymnosperm, spread quickly across the land

Answers

Answer:

C

Explanation:

Non vascular plants reproduce by spores or other asexual means

Attraction of pollinators is not an adaption of the seed. In angiosperms the colorful petals attract pollinators.

adaptations of seeds is their ability to store food, be dormant for preservation. They do not adapt to spread across the land via Gymnosperms. seeds can spread around via animals who eat the fruit and move from place to place. Gymnosperms do not produce flowers, so they don't have fruits. Though wind may blow their seeds, it's still not an adaptation.

Gymnosperm plants important adaptation of the seed allowed plants to spread quickly across the land.

So, option D is correct option.

Non vascular plants reproduce by spores or other asexual means.Attraction of pollinators is not an adaption of the seed. In angiosperms the colorful petals attract pollinators.The seeds spread around via animals who eat the fruit and move from place to place. Gymnosperms do not produce flowers, so they don't have b.

what do you mean by bacteria?​

Answers

Answer:

Bacteria is a type of micro-organism and is also a prokaryote. These organisms can only be seen using a microscope. Some bacterias are harmful while some are helpful for human daily lives, such as probiotics, and are necessary for life. They have simple cell structures as there is no nucleus or membrane-bound organelles. Bacterias can be found in soil, water, plants, animals, etc. They can cause diseases such as Tuberculosis etc. Due to some diseases being caused by bacterias, doctors prescribe Antibiotics which has the ability to stop the activities in bacterial cell that causes it to lose its protective outer covering and completely stops it from multiplying.

Answer:

Bacteria are among the smallest living things. A single bacterium consists of just one cell, and is called a single-celled, or unicellular organism.

Even though it is just a single cell, it can carry out all seven life processes (movement, respiration, sensitivity, growth, reproduction, excretion and nutrition).

D. The Brachiopods must be older than the plante

Answers

Answer:

Explanation:

because the plants are farther down lol

Paleontology establishes the geological age of the organisms. Based on the height of the fossils discovered at the Grand Canyon, it can be concluded that plants were older than the Brachiopods. Thus, option C is correct.

What are fossils?

The dead remains and decaying materials of the plants and animals stored and preserved under the sediments and rock layers over a period of many years are said to be called fossils.

The fossils are evidence of the evolution as well are used to determine the geological age of the species based on their occurrence of them in the rock layers.

The fossils of plants like horsetails and ferns were found 300 ft above the Canyon while Brachiopods at 10 feet above Canyons that tell that plants were found earlier than the former species.

Therefore, option C. the plants existed prior to the Brachiopods.

D. Lemurs isolated to the island of Madagascar

Answers

Answer:

D. Lemurs isolated to the island of Madagascar

Explanation:

Endemic is to be native and restricted to a certain place.

Endemic species are organisms that are limited and confined to a particular region. Lemurs show endemism as they are isolated to the island of Madagascar. Thus, option D is correct.

What is Endemism?

Endemism is a biological term used to depict the distribution of the organism in an area that becomes its habitat. It is shown by species that are limited and bounded to one geographical location.

Endemism is shown by the species due to genetic isolation that separates the population or the species in a geographical area and does not allow the genetic material to exchange by reproduction.

Koalas and Kangaroos in Australia, Lemurs in Madagascar, lion-tail macaque and Nilgiri blue Robin in India, and camellia plant in Japan are some endemic species.

Therefore, option D. the Lemurs in Madagascar are an example of endemic species.

Why are NADH and FADH2 necessities in the electron transport chain?


They power the electron transport chain.



They remove electrons from the electron transport chain.



They move down the electron transport chain.



They move electrons to the electron transport chain.

Answers

Answer:

D). They move electrons to the electron transport chain.

Explanation: Just took the quiz

NADH and FADH₂ are necessities in the electron transport chain because: They move electrons to the electron transport chain. (Option D)

NADH (nicotinamide adenine dinucleotide) and FADH₂ (flavin adenine dinucleotide) are molecules that play a crucial role in the electron transport chain (ETC) of cellular respiration. These molecules are electron carriers that are generated during earlier stages of cellular respiration, such as glycolysis and the citric acid cycle.

In the electron transport chain, NADH and FADH₂ donate the electrons they have gained from the breakdown of glucose and other molecules. These high-energy electrons are then passed along a series of protein complexes embedded in the inner mitochondrial membrane. As the electrons move through these protein complexes, their energy is used to pump protons (H+ ions) across the inner mitochondrial membrane, creating a proton gradient.

The proton gradient generated by the movement of electrons is used to drive the enzyme ATP synthase, which synthesizes ATP (adenosine triphosphate) from ADP (adenosine diphosphate) and inorganic phosphate. This process is known as oxidative phosphorylation.

In summary, NADH and FADH₂ are essential in the electron transport chain because they provide the high-energy electrons needed to establish the proton gradient, which ultimately powers the synthesis of ATP through oxidative phosphorylation.
