Stone tools are found on their own because they do not decompose and stay as they are.

In the broadest definition, a stone tool is any tool that is manufactured totally or mostly of stone.

Some stone tools were used for chopping fruits and roots as well as for cutting flesh and bone, removing bark from trees, and cutting into hides, or animal skins. A few of them served as handles. Some were used to create hunting spears and arrows.

Early human creations, such as stone tools and other artifacts, provide information on how people lived, interacted with their environment, and changed over time. Thousands of archaeological sites have been investigated, excavated, and dated during the last 2.6 million years.

Answer:answer is b and d

Explanation:

Birds with larger bills (on average) specialize in cracking hard, thick-walled seeds and Birds with smaller bills (on average) feed on seeds with softer seed coats, but if climate change results in most of the seeds in the area becoming thick-walled, then only birds with larger bills will survive.

Natural selection selects the best and fittest individuals so that the population or species can grow further, as in this case, where both types of finches are present, but due to climate change, only the seeds with thick walls survived, and the birds that can eat these will survive, while the rest will be removed from the environment.

Hence, birds with larger bills (on average) specialize in cracking hard, thick-walled seeds and Birds with smaller bills (on average) feed on seeds with softer seed coats, but if climate change results in most of the seeds in the area becoming thick-walled, then only birds with larger bills will survive.

Answer:

I think option B is right answer

Answer:

B) Image 1 -> Image 3 -> Image 4 -> Image 2

Explanation:

The pictures of the ecosystems are needed to be put into the simplest -> complex order.

Image 1 could be the simplest as it only has one organism.

Image 3 would be the next simplest as it has only a group of the same organism.

Image 4 would come next as it has aqua life and surroundings but the same fishes!

Image 2 would be the most complex, as it has various biodiversity and surroundings!

The order would go as Image 1 -> Image 3 -> Image 4 -> Image 2.

Answer:

As an embryo develops, identical cells give rise to specialized cells that perform different functions.

Explanation:

As an embryo develops, the cells divide, giving new ones. As the cells grow and continue to reproduce themselves, they differentiate, becoming specialized cells. These cells will be located in a particular part of the embryo and will perform a specific function. The shape, size, and organelles vary according to their role.

Answer: G. Horses slowly developed over time

Explanation:

Answer:

The correct answer is -

A. genotype ration = 1/1 or 100% of Aa.

B. phenotype = all smooth-seeded.

Explanation:

According to the question, in this experiment, the smooth seed is the dominant trait over the wrinkled seed. The wrinkled seed is recessive, therefore, represented by aa and dominant is represented by AA

gametes: A and A from smooth seeded parent and a and a from the wrinkled-seeded parent.

Punnett square:

       A          A

a      Aa       Aa

a      Aa       Aa

In this cross of F1 generation, all the offsprings are Aa in genotype 4/4 or 1/1 or 100 percent chances.

And phenotypically 100% chances of the smooth seed plants.

Answer:

c

Explanation:

it uses percentages, like 50% Aa, 25% aa and 25% AA

Answer:

Variation occurs in species with the genes resulting in the traits and physical characteristics that make it possible for them to be among the fittest for a number of reasons:

1. Mutation

2. Recombination and

3. Migration

Explanation:

Mutations:  A mutation is a deviation from the norm in a DNA sequence. It can be stimulated by errors during the DNA replication process which happens as the cell is dividing, or by exposure to ionizing radiation, chemicals, or viral infection (whether artificial or natural).

It is noteworthy that naturally, without any human intervention, the possibility of a spontaneous mutation is very low.

Recombination: This refers to the creation of new fusion of genes in the offspring that did not occur in the parents by the processes of crossing-over and independent assortment. Independent assortment meaning that the allele the gamete received for one gene was not influenced by the allele received for another gene.

Migration: Variation by migration here refers to the introduction of new genes from into one population by another. This could happen when a new population arrives at an existing one or when an existing one migrates to another population.

We can say for example that, genes from Americans have “migrated” into the population of African origin in America given the continuous immigration of Africans into America.

So in both populations, there are very fit species, but when their genes are mixed during cross-reproduction, variation arises.

High CO2 levels cause plants to thicken their leave ,which could worsen climate change effect researchers says.

plant scientists observed that when CO2 levels increase in the atmosphere most plants do unusual , they thicker their leave

germination increase in high temperature up to the point

Increased CO2 levels and temperatures affect plant growth by bringing about a corresponding increase.

This the process in which plants manufacture their food through the presence of sunlight.

other compounds such as CO2 and water are used which is why increase in the CO2 levels and temperatures will increase the growth of plants.

Biome that receives a lot of rain, moderate temperatures, and a long growing season is grassland. Thus, option D is correct.

Ecosytem is defined as a community that is biological by nature and the organism in that community attract with each other as well as their physical environment. Ecosystem is consist of both biotic as well as abiotic factor. The living components of ecosystem comes in category of biotic factor and non living components of ecosystem comes in category of abiotic factor.

Biodiversity is all the different kinds of life living in a particular area like the varity of animals, plants, fungi and microorganisms like bacteria and virus that plays a major role in framing of natural world usually three levels of biodiversity are observed and these are genetic species, and ecosystem diversity.

Biodiversity is very important for the process that's support all life present on earth including human.

Answer:

Natural Selection & Fitness

Explanation:

Horses have evolved to run as fast as possible because they are prey animals.

The hooves give advantages to the predecessors to the modern horse rather than the foot-bearing horses.

Thus when somebody inevitably becomes a snack, the hoof bearing horses lived longer. (Natural selection)

Because they've lived longer, they've had more babies. (Fitness)

Their babies are more likely to pass on the genes they've inherited from their successful parents, and the population of hooved-horses begins to exceed the population of footed-horses.

In this circumstance, all the footed-horses are gone. The population has evolved.
