Why do humans have fewer chromosomes than chimps?

Chimpanzees have 48 (24 pairs) chromosomes while man has 46 (23 pairs). This is due to the fact that one pair of chromosomes fused during the course of human evolution. Chromosomes have end cap markers called "Telomeres" to protect them from damage. They also have a marker called "Centromeres" that shows where splitting (mitosis) happened in the center of the chromosome. Scientists found in 2004 that the center of human chromosome #2 had two connected Telomeres, meaning that the ends of two chromosomes had fused. For more, see:

Hillier et al (2004) "Generation and Annotation of the DNA Sequences of Human Chromosome 2 and 4," Nature 434: 724-731

Cancer cells undergo mitosis at an abnormal or decresed rate?

Cancer cells undergo mitosis at an increased rate and there can be a number of reasons for this. Either the receptors on the cell surface membrane of some cells have been permanently activated and so they continue to divide even in the absence of growth factors. Also, excessive amounts of growth factors can be coded for which will also lead to increased division. In addition, there could be a mutation in tumour-supressor genes which means that they are no longer able to inhibit cell division which then accelerates. Activated oncogenes can also directly cause cell replication by activating intracellular pro-proliferation pathways (ras, myc, etc.). You can say that cancer is due to abnormal cell division but you can't sat that it is at a decreased rate.

Give two examples of how cell structures relate to cell functions?

The mitochondria's structure, with its inner membrane folded into cristae, enables it to produce ATP efficiently through aerobic respiration, supporting the cell's energy needs. The endoplasmic reticulum's extensive network of membranes provides a large surface area for protein and lipid synthesis, aiding in the production and modification of biomolecules for cellular functions.

What structures do the two types of cells have in common?

If by "the two types of cells" you mean plant and animal, then:

Nucleus

Mitochondria Cell membrane

Endoplasmic Reticulum

Ribosomes

Vacuole

Golgi Bodies/Apparatus

Lysosomes (more common in animal cells)

Only plant cells have cell walls and chloroplasts.

If you mean Prokaryotes vs. Eukaryotes:

Eukaryotic cells contain what is shown above.

Prokaryotic cells contain nothing but nuclear information floating free (nucleoid) and ribosomes surrounded by a cell membrane and wall. They also have a flagellum to move about with.

All cells contain cytoplasm.

Do carnivores have warm or cold blood?

Carnivores, like all mammals, are warm-blooded animals. They can regulate their body temperature internally to maintain a stable and warm temperature regardless of the external environment. This ability allows them to be active and hunt for prey efficiently.

How does the water cycle impact the tropical rain forest?

The water cycle in tropical rainforests plays a crucial role in maintaining the ecosystem's biodiversity and supporting plant growth. The cycle helps regulate temperature, brings much-needed rainfall to the region, and enables plants to absorb water through their roots. This abundance of water also sustains a wide variety of flora and fauna in the tropical rainforest.

What are the characteristics of the stomach?

The stomach is a muscular organ located in the upper abdomen. It stores and breaks down food through muscular contractions and the action of digestive enzymes. The stomach also secretes acid and enzymes to aid in the digestion process.

The mass of cells that result from uncontrolled cell growth?

The mass of cells that result from uncontrolled cell growth is called a tumor. Tumors can be benign (non-cancerous) or malignant (cancerous). Malignant tumors have the ability to invade surrounding tissues and spread to other parts of the body.

Are hominids carnivores?

Hominids, including humans, are omnivores, which means they consume both plant-based and animal-based foods. Our ancestors likely adapted to eating a combination of plant and animal resources to meet their nutritional needs.

Where did Jane Goodall sleep when she was with the chimps?

Jane Goodall slept in a tent while she was studying chimps in the wild. She wanted to fully immerse herself in their environment and behavior, so she opted to live among them in the forests of Gombe Stream National Park in Tanzania.

Which of these was not a characteristic of hominids lived that lived before humans?

One characteristic that was not common among early hominids was the ability to create complex tools and technology. This advanced cognitive ability is considered a defining feature of the Homo genus, which includes modern humans.

A seesaw has a 20ft board if you weigh 120 pounds and the fulcrum is 15ft from your end how much should your seesaw partner weigh for easy ups and downs?

To balance the seesaw, your partner should weigh 144 pounds. This is because the weight of each person multiplied by their distance from the fulcrum should be equal. So, 120 pounds × 15ft = Partner's weight × 20ft, which amounts to 144 pounds.

This ecosystem is hot and humid all year longchameleons toucans and chimpanzees all live here?

It sounds like a tropical rainforest ecosystem. This type of ecosystem is characterized by high temperatures and humidity year-round. Chameleons, toucans, and chimpanzees are all species commonly found in tropical rainforests due to the abundant vegetation and diverse habitats they provide.

Does Jane Goodall have a pet chimp?

Jane Goodall is a renowned primatologist who is known for her work with chimpanzees in the wild. She does not have a pet chimpanzee; her interactions with them have been primarily for scientific research purposes.

Why are echinoderms closely related to chordates?

most chordates are vertebrates, but some are not. invertebrate chordates belong to two of the subphylum of chordates. Cephalochordata and Urochordata. both invertebrate and vertebrate chordata have a dorsal nerve cord, a notochord, pharyngeal pouches and a postanal tail.

Does metaphase of mitosis meiosis 1or meiosis2 have the haploid number of chromosomes at the equator of the spindle?

In metaphase of meiosis 1, the haploid number of chromosomes is present at the equator of the spindle. Each chromosome is made up of two chromatids.

Is Jane Goodall lesbian?

There is no public information or evidence to suggest that Jane Goodall is a lesbian. Her personal life and sexual orientation have not been a focus of her work or public profile.

Jane Goodall why discovery important?

Jane Goodall's discoveries about chimpanzee behavior in the 1960s were important because they revolutionized our understanding of primates and helped bridge the gap between humans and animals. Her work showed that chimpanzees possess complex emotions, intelligence, and social behaviors previously thought unique to humans. Goodall's research continues to influence conservation efforts and our approach to studying and protecting wildlife.

What is some actions of Jane Goodall?

Jane Goodall is a renowned primatologist and conservationist known for her extensive research on chimpanzees in Tanzania's Gombe Stream National Park. She is also a prominent advocate for animal welfare, environmental conservation, and sustainable practices. Through her work and activism, Goodall has raised awareness about the importance of protecting wildlife and habitats.

What is another name for meiosis because the number is reduced from haploid to diploid?

Another name for meiosis, which results in the reduction of chromosome number from diploid to haploid, is reduction division.

What enzyme is produced by cells transformed with plasmid lux that is not produced by cells transformed with pUC18?

The enzyme produced by cells transformed with plasmid lux that is not produced by cells transformed with pUC18 is luciferase. This enzyme is responsible for the bioluminescent properties of animals like fireflies and glowworms. Cells transformed with plasmid lux will emit light in the presence of the substrate luciferin, whereas cells transformed with pUC18 will not.

What is used to make body cell's meiosis or mitosis?

In the process of meiosis, specialized cells called germ cells undergo two rounds of cell division to produce four haploid daughter cells. In mitosis, somatic cells undergo one round of cell division to produce two identical diploid daughter cells. Both processes involve complex molecular machinery, including proteins like cyclins and enzymes like kinases, to regulate the orderly progression of cell division.

What condition would result if mitosis is uncontrolled in the body?

Uncontrolled cell division occurs whenever a cell is incapable of responding to growth regulators that are released within it. This uncontrolled growth is cancer.

When cells begin to divide uncontrollably, your white blood cells come and destroy them before they form a tumor. However, sometimes your body fails to recognize these cells as a threat, or some of them get separated from the others and enter your bloodstream, which causes the cancer to spread. In cases like these medical help is needed to help kill the cancerous cells.
