Where does the energy & phosphates come from to create ATP?
Answer:
Most of the ATP in cells is produced by the enzyme ATP synthase, which converts ADP and phosphate to ATP. ATP synthase is located in the membrane of cellular structures called mitochondria; in plant cells, the enzyme also is found in chloroplasts.
Explanation:
Answer:
When the cell has extra energy it stores that enrgy
by reattcaching a free phosphate molecule to ADP, turning it back into ATP. The ATP molecule is just lile a rechargable battery.

Mark as brainliest:D
Answer:
The cytoplasm (also known as cytosol) is the protoplasm of a cell outside the cell nucleus. It is the jelly-like material plus the organelles outside the nucleus, and inside the cell membrane.
Many important functions of a cell take place in organelles, which are like bits of machinery for doing many jobs. The cytoplasm is highly structured: it is not some kind of soup, even though it is made out of 75–80% water.
The cytosol contains a complex mixture of cytoskeleton filaments, including the endoplasmic reticulum and the Golgi apparatus. It includes dissolved molecules, and water that fills much of the cell. Due to this network of fibres, membranes and the many dissolved macromolecules such as proteins, the cytosol does not act like a simple liquid. The main function of the cytoplasm is to hold the organelles in place

Explain how oxygen gets to your cells and waste gets out through the circulatory and respiratory systems.
Answer:
The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell. When oxygen passes into the bloodstream, carbon dioxide leaves it.

Brown-eyed alma has a blue-eyed mother and a brown-eyed father. In this case, her brown eyes were determined by a _____ allele.
In this instance, a dominant allele was responsible for her brown eyes.
Dominant alleles: what are they?A dominant allele is a gene variant that, even in the presence of other alleles, will cause a certain phenotype.Usually, a dominant allele codes for a protein that functions. One copy of the allele generates enough enzyme for a cell to have an abundance of a certain product, which is why the allele is dominant.What makes a gene a dominant allele?Because it hides the recessive trait and manifests in the phenotype of a heterozygous creature, a dominant allele is referred to as dominant. It takes just one allele to express the characteristic.learn more about dominant allele here

comparative profile for covid-19 cases from china and north america: clinical symptoms, comorbidities and disease biomarkers
Different people are affected by COVID-19 in various ways. The symptoms experienced by infected individuals have ranged widely, from little discomfort to serious sickness.
The susceptibility to and prognosis of severe acute respiratory syndrome caused by coronavirus 2 or coronavirus disease 2019 (COVID-19) have been found to vary greatly amongst individuals and populations. Intervention in public health must take into account these variations and how they affect susceptibility to infection and the severity of disease. The distinctions between the COVID-19 case profiles from China and North America may be due to regional variations in host, environmental, and healthcare-related factors. These inter-population variances, together with intra-population variability, highlight the need to identify how health inequities and inequalities affect the public health response to COVID-19 and can help with preparing for the epidemic's resurgence.Learn more about the COVID-19 with the help of the given link:

Mitosis as well as meiosis are both types of division of the nucleus in the eukaryotic cells. The complete diagram shows that Meiosis comprises of two nuclear divisions which lead to the formation of four nuclei which are generally divided resulting in the creation of four new haploid cells.
The nuclei that are formed by the process of meiosis are not genetically identical unlike mitosis. During Meiosis I, the synapsis of homologous chromosomes occurs, chiasmata formation and crossing over takes place. The sister chromatids also align along the Metaphase plate in tetrads.

(2) We cannot see or observe the blackhole.
A stellar nursery was a sort of nebula where young stars were created by the pressure and heat of colliding energy. Blackhole.
Why do we can not see blackhole?
A black hole is an area in space where gravity is so intense that not even light can escape. The gravity is very strong since the stuff is compacted into such a small space. This might occur when a star ages. Humans cannot see black holes because light cannot escape from them.
This suggests that from a distance, the gravitational field of a black hole like this one is identical to the gravitational field of any other spherical object with the same mass.
