Answer:

C The sarcomere is contracted, and the actin and myosin filaments are completely overlapped.

Explanation:

In rest, the tropomyosin inhibits the attraction strengths between myosin and actin filaments. Contraction initiates when an action potential depolarizes the inner portion of the muscle fiber. Calcium channels activate in the T tubules membrane, releasing calcium into the sarcolemma. At this point, tropomyosin is obstructing binding sites for myosin on the thin filament. When calcium binds to troponin C, troponin T alters the tropomyosin position by moving it and unblocking the binding sites. Myosin heads join the uncovered actin-binding points forming cross-bridges, and while doing so, ATP turns into ADP and inorganic phosphate, which is released. Myofilaments slide impulsed by chemical energy collected in myosin heads, producing a power stroke. The power stroke initiates when the myosin cross-bridge binds to actin. As they slide, ADP molecules are released. A new ATP links to myosin heads and breaks the bindings to the actin filament.  Then ATP splits into ADP and phosphate, and the energy produced is accumulated in the myosin heads, which starts a new binding cycle to actin. Finally, Z-bands are pulled toward each other, shortening the sarcomere and the I-band, producing muscle fiber contraction.

In the sarcomere, which is the contractile unit of skeletal muscles, there are

When the muscle contracts, the muscular fiber gets shorter and thicker due to the reduction in the length of the sarcomere. The H line and the I band get shorter. The Z lines get closer to the A band, meaning that they get closer to each other. A band keeps constant in length. This change is produced by movement mechanisms that involve a change in the relative position of actin and myosin filaments.

Answer:

Basically an Anti-Condon is a sequence of three nucleotides forming a unit of genetic code in a transfer RNA molecule, corresponding to a complementary codon in messenger RNA.

Explanation:

Codons are trinucleotide units that present in mRNA and codes for a particular amino acid in protein synthesis. Anticodon is trinucleotide units that present in tRNA. It is complementary to the codons in mRNA.

Answer:

What is this?????????????????????????

Answer:

DNA segments are exchanged between two non-sister chromatids during meiosis I.

Explanation:

An exchange of chromosome segments or parts between non-sister homologous chromatids occurs which is also called crossing over. This crossing over occurs in the meiosis I that is responsible for the variation in the offspring produced. The formation of hybrid species occurs due to this exchanged of DNA segments between two non-sister chromatids.

Answer:

C

Explanation:

The water won't be able to penetrate the ground so can't become ground water and reservoirs are usually above ground not underground so it will become run off.

Permeability is the ability of the substances to get diffused easily across the surface. The concrete ground results in the rainwater becoming runoff. Thus, option C is correct.

Permeability is the capacity of the water or any fluid to pass and diffuse across the substances or any membrane to get from the higher to lower concentration.

The concrete ground and roads are not permeable and do not allow water to pass through the material and effects the collection of the rainwater through infiltration.

The rainwater is unable to filter into the groundwater and becomes runoff. This runoff gets accumulated on the roads and can even lead to floods and drain blockages.

Therefore, option C. the less permeable roads cause rainwater to become runoff.

Answer:

It's A

Explanation:

Had it on a test

Humans are considered animals because as in animals zygotes after cell division turns into a blastula, hence option a is correct.

More than any other species, humans are capable of learning new things. Indeed, the majority, but not fully, of what distinguishes us from other animals is anchored in language.

In addition, because we have a backbone, humans are considered to be members of the chordate animal phylum.

The zygote is split into the blastula after fertilization, three germ layers develop in the blastula, which in some species is a hollow ball of cells, during a process known as gastrulation.

Therefore, humans are classified as members of the primate order within the animal group and having the blastula stage, hence option a is correct.

Methods of waste disposal are :-

Biogas plant: - Biodegradable material is used to produce biogas and manure.

Sewage treatment plant: The drain water is treated at plants before adding it to river.

Land filings: - The waste are buried in low-lying areas and compacted with bulldozers.

Composting: - Organic waste are filled in compost pit to make compost for plants.

Recycle: - This means that you collect plastic, paper, glass and metal items and recycle these materials to make required things instead of synthesizing or extracting fresh plastic, paper, glass or metal. In order to recycle, we first need to segregate our wastes so that the material that can be recycled is not dumped along with other wastes.

Reuse: - This is actually even better than recycling because the process of recycling uses some energy. In the ‘reuse’ strategy, you simply use things again and again. Instead of throwing away used envelopes, you can reverse it and use it again. The plastic bottles in which you buy various food-items like jam or pickle can be used for storing things in the kitchen.

Refuse: -This means to say No to things people offer you that you do not need. Refuse to buy products that can harm you and the environment, say No to single-use plastic carry bags.

Repurpose - This means when a product can no more be used for the original purpose, think carefully and use it for some other useful purpose. For example, cracked crockery, or cups with broken handles can be used to grow small plants and as feeding vessels for birds.

Organic compounds contain carbon atoms bonded to other atoms. The correct option is A.

Any of a wide area of chemical compounds in which one or many carbon atoms are covalently connected to atoms of other elements, most commonly hydrogen, oxygen, or nitrogen.

Carbides, carbonates, and cyanides are among the few carbon-containing compounds that are not classified as organic.

The main distinction between organic and inorganic compounds is that organic compounds always contain carbon, whereas most inorganic compounds do not.

Furthermore, almost all organic compounds contain carbon-hydrogen or C-H bonds.

Organic foods are grown without the use of synthetic pesticides, fertilizers, or herbicides.

Organic meat, eggs, and dairy products are derived from animals that have been fed natural feed and have not been given hormones or antibiotics.

Thus, the correct option is A.
