Which structures are least likely to appear in the same eukaryotic cell?
A. mitochondria and chloroplasts
B. ribosomes and mitochondria
C. a cell wall and chloroplasts
D. small vacuoles and a cell wall
Answer:
D. small vacuoles and a cell wall
Explanation:
Small vacuoles are found in animals, while cell walls are found in plant cells. Although plant and animal cells are both eukaryotic, the question asks if they would appear in the same cell which they would not.

Which statement describes the best evidence that two species share a recent common ancestor?
A) The species are about the same size.
B) The species eat the same type of food.
C) The species live in the same ecosystem.
D) The species have similar DNA sequences.
Answer:
I hope this helps you :)
Explanation:
Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.
The statement that describes the best evidence that two species share a recent common ancestor is that the species have similar DNA sequences, which is present in Option D, as the DNA is the genetic material.
What role does the DNA sequence play in evolution?DNA sequence comparisons have become an increasingly important tool in determining evolutionary relationships between organisms, and after comparing the DNA sequences of different organisms, scientists can determine the degree of similarity between them such as similarities in size, diet, or ecosystem may indicate some degree of similarity between two species, but they do not necessarily provide evidence for a recent common ancestor.
Hence, the statement that describes the best evidence that two species share a recent common ancestor is that the species have similar DNA sequences, which is present in Option D.

Describe the flow of a river from beginning to the end
Use the following terms: headwaters, springs, tributaries, confluence, and mouth
The flow of river begins with the Headwater .
Springs are warmer water bodies compared to rivers,
The rivers connect to another river to form a confluence
Rivers flow into larger water bodies in the form of tributaries.
The mouth of the river flows from a larger source to a smaller body of water.
Describing the flow of a riverThe flow of river begins with the Headwater ( the beginning of the river ), springs are warmer water bodies compared to rivers, When the rivers flow they connect to another river ( confluence ) which flow into larger rivers in the form of tributaries while the mouth of the river flows form a larger source to a smaller body of water.

Which of the following types of power does not use a turbine to generate
electricity?
O A. Wind
B. Nuclear
C. Coal
O D. Solar
D. Solar
Explanation:
Solar converts sunlight directly into electricity without the need of a turbine
Solar does not use a turbine to generate electricity. Therefore, option (D) is correct.
What is Solar power?
Solar power is a renewable and sustainable energy source that generates electricity by harnessing the energy from the sun. It is a clean energy alternative to fossil fuels, as it does not produce harmful emissions or pollutants that contribute to climate change.
Solar power systems use photovoltaic (PV) cells, which convert sunlight into direct current (DC) electricity. An inverter then converts the DC electricity into alternating current (AC) electricity that can be used in homes and businesses.
Solar power is becoming more affordable and accessible, and many governments around the world offer incentives to encourage the installation of solar panels. The growth of solar power has the potential to reduce greenhouse gas emissions, create jobs, and provide energy access to remote communities.

What is the genetic make-up of an organism?
Answer:
Explanation:
In a broad sense,genetic makeup of an organism can be regarded as the
"genotype" . It gives description about
complete set of genes an organism.
If we narrow it, it can be reffered to as "alleles" , this is is variant forms of a gene which is been carried by an organism. For instance, Humans can be regarded as diploid organisms, i.e there are two alleles at their each genetic position along with one allele which is been inherited from each parent. genotype of a specific gene is been represented by "Each pair of alleles". Instance of this is of "sweet pea plants" the gene responsible for flowering color posses two alleles, One of the alleles is responsible for coding purple flowers, symbolized with
uppercase letter F, the other allele is responsible for coding of white flowers
symbolized with Lowercase letter" f "
There are three possible genotypes which could be featured for Different population of a sweet pea, which are
✓FF
✓Ff
✓ ff.
Genotype of each plant have some contribution to the phenotype, by saying this, we mean outward appearance of its flowers.

The genetic researchers at Bay Medical Company are interested in spiders with the trait for medium silk flexibility. They
think this sik can be used for medical purposes such as for making stitches and for creating artificial tendons. Why do
you think offspring B has the medium silk flexibility trait?
Answer:
Due to similar shape.
Explanation:
I think offspring B has the medium silk flexibility trait because this offspring B is identical to the spider that is responsible for medium silk flexibility trait. There are some offspring identical to male parent spider due to the presence of dominant allele whereas very littles number of offspring is similar in appearance with the female spider due to recessive allele. If the male spider has medium silk flexibility trait so more number of offspring has medium silk flexibility trait as compared to others.
The people at the Medical research bay company are researching on spiders. the trait for the medium silk flexibility. The silk can be used for medical purposes and creating other tendons.
