Recent discoveries in a cave at Pinnacle Point, South Africa, suggest that humans had achieved behavioral modernity as early as 164,000 B.P. All of the following were found at this site EXCEPT evidence of:_______
a. a diet that included shellfish and other marine resources.
b. the very early use of pigment, likely for symbolic behavior.
c. animal butchery for the first time.
d. bladelet stone-tool technology, previously dating to 70,000 years ago.
e. the human capacity to exploit coastal environments.

Answers

Answer: C. Animal butchery for the first time

Explanation: The discoveries in the cave suggest that humans were harvesting food from the sea (including shellfish and other marine resourses), the use of complex small stone tools and using red pigments in symbolic behavior 164,000 years ago.

A paleoanthropologist (with the Institute of Human Origins at Arizona State University); Curtis Marean, who was the Lead of the research team expressed the aforementioned discoveries while presenting their reports on the research.

He further indicate that these discoveries translates that humans must have been living along this coastal environment at that early time while exploiting it resourses.

1⁄4 cup fat free sour cream.

Pinto beans are added to tacos, burritos, and soups that are high in fiber.

What are fibers and their types?

The body is unable to digest fiber, which is a form of carbohydrate. While fiber cannot be converted into glucose, the sugar that results from the breakdown of most carbs, fiber travels through the body undigested.

The solubility, viscosity, and fermentability of dietary fibers, which have an impact on how they are metabolized by the body, can be used to classify them in general. Dietary fibers have a wide range of chemical compositions.

Fibre comes in two varieties: soluble and insoluble. Both are crucial for good health, digestion, and illness prevention. Thus, Pinto beans are added to tacos, burritos, and soups that are high in fiber.

what must be true about two objects if heat is flowing between them​

Answers

Answer:

The objects must be the same temperature.

Explanation:

if heat is flowing between two objects, so both ​the objects must have the same temperature because the heat in object 1 passes to the object 2 due to the conduction property present in these objects. The heat flows from one body to another body until both have the same amount of heat energy as well as temperature so that's why we can say that both objects must be the same temperature.

Should we clone animals that are going or have gone extinct (in other words bring them back

No, God gives and takes away, the world is heartless and kills entire species to extinction but it’s nothing that God didn’t already know would happen. Dinosaurs are no longer here there extinct for a reason, nowadays extinction comes from man but everything that happens in this world is Already written out in Gods book

Answer:

I think we should but people are preventing this though

Explanation:

I think we should because it might benefit the world and let scientists to discover this animal. But then I don't think so because animals that are/were extinct could perhaps be from climate change. Nowadays, people don't take this matter seriously causing habitats to be destroyed and animals to be extinct :) Like icebergs are melting that mean penguins are at risk of being extinct,if we did something then this situation will be prevented. However dinosaurs did become extinct and they did not come back so its probably just life and this is how god planned it:)

The 2 strands are copied differently. The [D] strand is made continuously, while the [E] strand is synthesized in small sequences called Okazaki fragments. The main enzyme involved in DNA replication is [F]. This enzyme can only add nucleotides to an existing strand, so short sequences of [G] made by the enzyme [H] are needed for the process of elongation. In the [U] strand, the enzyme DNA polymerase one removes the short tj sequences and fills the gaps, while [K] joins the fragments.

During the process of DNA replication, the whole molecule gets copied in the synthesis or S phase of the cell cycle. The DNA strands are separated by the enzyme helicase while topoisomerase keeps it from overwinding. The 2 strands are copied differently. The leading strand is made continuously, while the lagging strand is synthesized in small sequences called Okazaki fragments. The main enzyme involved in DNA replication is DNA polymerase. This enzyme can only add nucleotides to an existing strand, so short sequences of nucleotides (primer) made by the enzyme primase are needed for the process of elongation. In the lagging strand, the enzyme DNA polymerase one removes the short tj sequences and fills the gaps, while DNA ligase joins the fragments.

what can happen during the cycle of photosynthesis with increasing concentrations of Atrazine?

Answers

Answer:

By inhibiting photosynthesis, Atrazine kills plants. Photosynthesis, which is unique to living green plants, occurs when light energy becomes the chemical energy required for food production.

Simply stated, plants eventually die of hunger when food production stops. Atrazine selectively kills unwanted plants (weeds) competing with suitable plants for water and nutrients (crops, turfgrass). It is thus a beneficial tool for both farming and urban plants.

Explanation:

In Texas maize and grain sorghum production, Atrazine is the most often used herbicide. In several "weed and feed" preparations for domestic plowing and commercial turf-grass weed control, it is also often found as an active ingredient.

With its broad use, atrazine has been identified in minute concentrations in Texas ground and surface waterways. Because of this, it is crucial to understand atrazine behavior in the environment and the potential for harmful impacts on human and animal health and on other non-target organisms.

Toluene crosses pure lipid bilayers many hundreds of times faster than a related compound, phenylalanine. Suggest two different properties of these molecules that would account for this difference.

Answers

Answer:

The lipid bilayer is hydrophobic that is hydrophobic and it can easily cross the lipid bilayer.

Toulene is a hydrophobic and neutral molecule compound so it can easily pass through the bilayer. It is an aromatic compound with a methane group attached to the benzene ring. It is smaller in comparison to Phenylalanine.

Phenylalanine-- It is an amino acid with a benzene ring attached to it. This amino acid is less hydrophobic than the aliphatic amino acids. Because of its less hydrophobic nature, it travels slowly compared to Toluene. It is also larger and has amino and carboxyl groups attached to it. On the other hand, Phenylalanine is a polar compound which has -COOH and -NH2 group. which prevents its delay in its transport across the lipid bilayer.

What is Species?

A species is defined as the basic unit of classification. This is also taxonomic rank of an organism, as well as a unit of biodiversity.  These are the group of organisms which can reproduce with one another in nature and produce fertile offspring.

Species can be divided further on the basis of concept like

1. Typological or Essentialist Species Concept

2. Nominalistic Species Concept

3. Biological Species Concept

4. Evolutionary Species Concept

The species designation which originated in taxonomy, where the species is the basic unit of taxonomy is recognized by the International Commission on Zoological Nomenclature. Every species is have a standard two-part name of genus and species.
