A muscle cell's fundamental rod-shaped organelle is called a myofibril. They are made of several chains of myofibrils that are long, tubular cells known as muscle fibres.

What is myofibril and its function?

Sarcomeres, a muscle's functional units, make up myofibrils. The sliding-filament concept is used by the myofibril to produce muscle contraction. When tendons are at rest, the dense and thin filaments do not completely overlap, with certain regions having neither of the two types.

What are myofibrils are composed of?

The dense and thin myofilaments that make up the myofibrils are what give the muscle its rough appearance. Also with two other muscle regulating proteins, tropomyosin and troponin, the thick filaments are made up of strands of the protein myosin, while the thin filaments are made up of strands of the protein actin.

| Suggest two environmental factors that enable pine trees to photosynthesise in spring and summer in
Switzerland, but not in winter.

Answers

Answer: Temperature and light

Explanation:

In winter, day length is shorter than in spring/summer and the sun does not rise as high in the sky. There is also more cloud cover, fog and snow to reduce access and intensity of light.

Colder temperatures reduce metabolic activity, and at temperatures below zero, water uptake is prevented, which reduces transport of nutrients, and icing of needles and snow cover reduce access to carbon dioxide.

In spring/summer sunlight is more readily available, temperatures more conducive to carbon dioxide uptake and transpiration.

The  two environmental factors are Temperature and light

The following information should be considered:

In winter, day length is less than in spring/summer and the sun does not rise as high in the sky. There is also more cloud cover, fog and snow to reduce access and intensity of light. Colder temperatures decreased metabolic activity, and at temperatures below zero, water uptake should be prevented, which decreased transport of nutrients.

The pea aphid, a type of insect, contains light-capturing pigments in its exoskeleton. Scientists hypothesize the pea aphids gained the ability to synthesize these pigments from genes transferred from fungi during evolution. While pea phones do not have chloroplasts or fix carbon, researchers have found that pea aphids with more pigments have higher levels of ATP than those fewer pigments. Pea aphids also have been shown to increase production of ATP when exposed to sunlight.
Based on this information, is the pea aphid a true autotroph?

Answers

The pea aphid isn't a true autotroph because it is unable to use the energy from sunlight.

What is a true autotroph?

A true autotroph is an organism that produces biomass by a chemical process called photosynthesis.

Someone makes a loud noise and it scares you use complete sentences to put the following vocabulary terms in order to describe how the body processes the sound and reacts central nervous system, sensory organs, and sensory receptors

Answers

Answer:

When someone makes a loud noise and it scares you, your body goes through a series of processes to respond to the sound. I'll break it down using the terms you mentioned.

Explanation:

Sensory organs: These are specialized parts of your body that detect stimuli from the environment. In the case of hearing a loud noise, your ears are the sensory organs responsible for detecting sound waves.

Sensory receptors: These are specialized cells within your sensory organs that convert the stimuli, in this case, sound waves, into electrical signals that can be understood by your body. In your ears, tiny hair cells act as sensory receptors, converting the sound waves into electrical signals.

Central nervous system: This refers to your brain and spinal cord, which are the main components of your central nervous system. Once the sensory receptors in your ears convert the sound waves into electrical signals, these signals travel through nerves to reach your central nervous system.

So, in the situation where someone makes a loud noise, the sound waves are detected by the sensory organs (your ears), which then send the information to the sensory receptors (hair cells). The sensory receptors convert the sound waves into electrical signals, which are then transmitted through nerves to your central nervous system (brain and spinal cord).

Once the electrical signals reach your central nervous system, your brain processes the information and determines that the loud noise is something to be concerned about. It may trigger a response, such as a startled reaction or the feeling of fear. These responses are coordinated by your central nervous system, which sends signals to various parts of your body to react accordingly.

So, the order of the processes involved in how the body processes the sound and reacts to a loud noise is: sensory organs (ears) -> sensory receptors (hair cells) -> central nervous system (brain and spinal cord).

In the universal ABO blood grouping system, there are four phenotypes—A, B, AB, and O—which are determined by three different alleles. The presence of three alleles in the ABO blood grouping system is an example of ____.

Answers

Answer:

The correct answer is - autosomal codominant inheritance (due to multiple alleles).

Explanation:

Autosomal codominant inheritance or codominance is a pattern of inheritance where the alleles present of an autosomal gene express their character in the phenotype. In other words, in this type of pattern, no allele would be masked by other alleles and both will be expressed in the phenotype.

The human ABO blood group is an example of this pattern as there are three alleles A, B, and O. In the heterozygous case of AB blood group both A, and B alleles expressed together however, O is masked by both alleles A, and O.

The table shown below represents the number of species growing in an area that was logged using clear-cutting

Answers

No hablo inglés si me lo traduce lo ayudo

Here is an analysis of the changes in vegetation and species diversity based on the data:

In the first years after logging, the area was dominated by grasses, with 32 species present after 1 year. Shrubs and trees were initially absent. This indicates that grasses rapidly colonized the disturbed area after logging.

Over time, the number of grass species declined as shrubs and trees became established. Shrubs first appeared after 5 years and gradually increased, with 18 species present after 45 years. Trees were absent for the first 15 years but then increased to 24 species after 45 years.

The total number of species showed a steady increase over the 45 years, from 32 species initially to a maximum of 77 species after 45 years. This indicates that species diversity was low immediately following the disturbance but gradually recovered and surpassed the original diversity levels.

The pattern of changes suggests that after the initial disturbance of logging, grasses were the first vegetation to recover and colonize the open area. Then over time, shrubs and trees established and the plant community transitioned from grasses to shrubs to trees. This successional progression from early to later species resulted in an overall increase in species diversity as different types of plants colonized the area.

In summary, the key conclusions supported by the data are:

Grasses rapidly colonized after disturbance while shrubs and trees were initially absentShrubs and trees gradually established over time, replacing some of the grass speciesTotal species diversity increased as different vegetation types colonized, reaching maximum diversity after 45 yearsThe changes indicate a successional progression from early colonizers to later species that resulted in higher diversity.
