Why does the law of conservation of energy only apply to closed systems

Answers

The Law of conservation of energy only applies to closed systems that can't exchange energy with their environment.

The law of conservation of energy, also known as the first law of thermodynamics states that the energy in a closed system must remain constant and cannot increase or decrease without outside influence. In an open system, both energy transfer and mass transfer take place. Therefore, both the law of conservation of energy and the law of conservation of mass is taken into account.

Storage rights cannot be applied to open systems because by definition things can be put into and taken out of open systems. So you can always add charge momentum energy etc. to open systems. Non-insulated and insulated systems, energy conservation. To solve the work and energy problem, we need to identify the systems we work with.

Answers

Despite the fact that humans (and all other diploid species) can only have two alleles for a given gene, a population can contain multiple alleles and thus a large number of combination of two alleles of can be observed.

What are alleles?

Alleles are variations of the same nucleotide sequence at the same position in a long DNA molecule, as described in major textbooks on genetics and evolution.

In humans, when a sperm cell fertilizes an egg cell, the fertilized egg cell inherits her 23 chromosomes from each parent. Each pair of matched chromosomes contains the same set of genes, but each locus has a unique allele for each gene.

This inheritance means that an individual has two copies of the gene for a particular trait. one from her mother and one from her father. These are said to be the maternal and paternal alleles. These allelic interactions are responsible for their unique trait.

______ is the cell division process that occurs in diploid germ cells and gives rise to haploid cells.

Answers

Answer:

Meiosis

Explanation:

In human, there are somatic cells and germ cells. Sperm and egg are called as germ cells or gametes which can be found in gonads (testis and ovarium).

In beginning, the gametes are diploid or have 46 chromosome (23 pairs). Diploid means contain two sets of chromosome.

To maintain the homestatic in terms of quantity of chromosome, each gamete, either sperm or egg must be haploid or only have one set chromosome (23 chromosome).

To make it happen, each gametes undergo a process named spermatogenesis and oogenesis. After the gametes (diploid) are duplicated through mitosis, the gamete will be divided through meiosis for producing gametes (haploid). Meiosis is a type of division cell that reduce the number of chromosome, from diploid to haploid.

As the gametes, sperm and egg (haploid) fuse together in sexual reproduction, it can back into the double chromosome (diploid).

During prophase, a stage in the cell cycle, Option C.  the nuclear envelope breaks down.

At some stage in prophase, the complicated DNA and proteins contained in the nucleus, called chromatin, condenses. The chromatin coils and will become increasingly compact, ensuing in the formation of seen chromosomes.

Throughout prophase, chromatin condenses into chromosomes, and the nuclear envelope, or membrane, breaks down. In animal cells, the centrioles close to the nucleus start to separate and move to contrary poles (facets) of the mobile.

A cell's genetic DNA condenses, spindle fibers start to shape and the nuclear envelope dissolves. What occurs all through Metaphase? The duplicated chromosomes line up and spindle fibers connect with the centromeres.

Which two hormones regulate calcium levels in the blood?

Answers

Explanation:

Both parathyroid harmone and calcitonin help regulate the level of calcium in your blood.

Calcitonin and parathyroid hormone work together to control blood calcium levels, which are crucial for a number of vital biological processes.

When the blood calcium level is high, calcitonin is released. It subsequently reduces the levels by preventing bones' release of calcium ions. Contrarily, the parathyroid hormone raises the blood calcium level by enhancing intestinal calcium absorption and moving calcium from bones into the blood.

A hormone called calcitonin works to control the amount of calcium in your blood by lowering it. Your thyroid gland's C-cells generate calcitonin. It doesn't seem that having abnormally high amounts of calcitonin in your body has any immediate drawbacks.

Your parathyroid glands produce a hormone called parathyroid hormone (PTH) that regulates the amount of calcium in your blood. It also regulates the amounts of vitamin D and phosphorus. Parathyroid hormone over- or under-production might result in symptoms linked to abnormal blood calcium levels.
