The ancestral species that fossil record indicate was the earliest habitual hunter is Homo erectus.
When did Homo erectus appear in the fossil record?Fossils from Southeast Asia show that H. erectus populations is one that has survived until close to the end of the Pleistocene, after making its first appearance in the fossil record from places in the region of Lake Turkana Basin, Kenya, circa about two million years ago.
Homo erectus, which is said to have a comparatively extended legs as well as shorter arms, is said to be the oldest species that is ever known to have a body that resembles a person.
Note that It is one that is often standing straight. Scientists have determined that H. pylori that lived in the Turkana Boy skeleton, a remarkably complete skeleton. Therefore, habitual hunters are know to be evidence of Homo erectus.

Which structures does a single cell organism need for movement? question 3 options: cilia and flagella mitochondria and cytoplasm ribosomes and nucleus cilia and cytoskeleton
The structures that a single-cell organism need for movement include cilia and flagella (Option A).
What are cilia and flagella?Cilia and flagella are subcellular structures that cells use to move in the surrounding media. These structures are composed of monomers that connect each other and they can suffer polymerization-depolymerization cycles in order to maintain a movement in response to environmental stimuli. For example, cilia are composed of microtubules that link to the plasma membrane.
Therefore, we can conclude that cilia and flagella are structures of the cytoskeleton that help microorganisms to move in their surrounding environment.

I have a plate that hangs in my house on our wall with a picture of him and that is how he looks.

Which component could be added to complete this chemical equation?
light energy
ATP and NADPH
chemical energy
rubisco
Answer: Light energy is the element that may be included to complete this chemical equation. The correct answer is A.
Explanation:
Photosynthesis: The process of producing food by plants and other organisms that possess chlorophyll is known as photosynthesis. As a byproduct of the process, oxygen is released along with glucose.
Water and carbon dioxide are required for photosynthesis, which can only occur in the presence of sunlight. Upon completion, glucose is produced as an energy source and oxygen is released as a byproduct.
Only creatures that contain chlorophyll can carry out the process because chlorophyll helps to catch sunlight to complete it. Chlorophyll is found in plant leaves.

Mammals have a large amount of parental care, where one or both parents assist with the nurture of the newly-born offspring. Female wolves nurse and protect their pups for months. Chimpanzee offspring are cared for by the parents for several years. Although mammals have fewer offspring per reproductive event than fish, reptiles, and amphibians, their survival throughout their juvenile period is much higher. However, there are a few species of tropical frogs that lay eggs, but both parents tend to care for the offspring after they hatch. The male frog guards the eggs while the female frog assists in feeding the larvae after they hatch. Based on the passage, what makes a researcher infer that the survival rates are higher for tropical frogs than other frog species in general?
Answer:
Biparental care allows the energetic demands to be shared between both parents, which can improve the number of surviving offspring

in addition to epinephrine, your body also releases a steroid that responds to stress. epinephrine wears off quickly, but the steroid, corticosterone, can last hours. where we would predict that corticosterone (the signaling molecule) would bind to its receptor?
The glucocorticoid receptor (GR, or GCR) also known as NR3C1 (nuclear receptor subfamily 3, group C, member 1) is the receptor to which cortisol and other glucocorticoids bind.
By interacting with mineralocorticoid and glucocorticoid receptors in the brain, corticosteroid hormones help the body adapt to stress (MR and GR). These receptors serve as important transcription factors in considerable part.
The glucocorticoid receptor controls how the body will react to stress, even though cortisol is a blatant indicator that stress is there. A mechanism that affects the production of specific stress-response proteins is activated when cortisol binds to the glucocorticoid receptor.

How many cells are there are each of the beginning of the cell cycle?
There is just one cell at the start of cell division or the cell cycle.
A mother cell divides twice, once through mitosis to produce two daughter cells and once through meiosis to produce four daughter cells.
What are cell division and cell cycle?The cycle of a cell's growth and division entails a variety of processes. A cell spends the majority of its time, known as interphase, developing, duplicating its chromosomes, and preparing to divide. The cell continues its division process through mitosis after exiting interphase. Each of the freshly produced cells, known as daughter cells, enters its own interphase and initiates a new cycle of the cell.
The two different cell division processes are meiosis and mitosis.
During the mitotic cell cycle phase, which is also known as division, replicated chromosomes are split into two new nuclei. Cell division known as mitosis creates genetically identical cells with a conserved chromosome number.
In sexually reproducing mammals, meiosis is a special type of germ cell division that produces gametes, such as sperm or egg cells. After two rounds of division, four cells with a single copy of each chromosome are created.

4. Recessive genetic trait = necessary for both parents to carry the gene, whether or not they themselves are redheaded
Explanation:
Hope this helps.
Answer:
Explanation:
1. Lighter colored eyes like blue, hazel and green
2. Lighter colored eyes like blue, hazel and green have less of a pigment called 'melanin' than brown eyes do. Melanin helps protect the retina from UV damage and blue light, putting those with blue eyes at a higher risk of developing UV-related eye damage.
3. Natural red hair
4. Natural red hair is the rarest hair color in the world, only occurring in 1 to 2% of the global population. Since red hair is a recessive genetic trait, it is necessary for both parents to carry the gene, whether or not they themselves are redheaded. Due to this there are more people who carry the redhead gene, than there are people with red hair.

The correct answer is option D: ribosomes translate DNA code to RNA code.
During protein synthesis, ribosomes translate DNA code to RNA code.
Universally, ribosomes are responsible for the synthesis of proteins through the translation of genetic information with the help of mRNA as they code particular amino acids which are the key units of protein synthesis.
These are manufactured as a result of the processing of genetic code into messenger RNA i.e. mRNA through triplet RNA basis known as codons.
Moreover, ribosomes also function as catalysts to accelerate the process of protein formation by continuously supplying amino acids to the polypeptide chain.
During this reaction, transfer RNA i.e. tRNA server as a carrier of amino acids to ribosomal sites where translation of DNA code to RNA code occurs for protein synthesis.
