Answer:
Neanderthals
Explanation:
Homo sapiens encountered neanderthals in europe and had offspring.
The prior species of hominids that Homo sapiens encounter in Europe approximately 40,000 years ago is Neanderthal.
What is species?
Species is the term that is used to classify different organisms. Species is the second last classification, which means most similar organisms are present in this classification. The traits are mostly similar in these organisms.
While the form of the head and face was not significantly different from that of current humans, there were still quite a few distinctions. Most notably that of the modern human head, which is shorter and has a less prominent facial front. Neanderthal was a former human.
Therefore, the Neanderthals are the ancestors of Homo sapiens, who first encountered them in Europe some 40,000 years ago.

If a srna is bound to the ribosome binding sequence of a mrna coding for an enzyme in a bacteria, what effect will this have on the amount of enzyme in this cell?.
If an sRNA is bound to the ribosome binding sequence of an mRNA coding for an enzyme in a bacteria, it will reduce the amount of enzyme.
What is an sRNA?A small RNA (sRNA) is a short sequence that binds to target mRNAs by base complementarity and thus reduces gene expression.
These sequences (sRNAs) can efficiently block prokaryotic translation in order to reduce the amount of protein.
The sRNAs have fundamental regulatory roles both in bacterial translation and protein production.

Earthquakes also produce transverse waves that move more slowly than the p-waves. These
waves are called secondary waves, or s-waves. If the wavelength of a s-wave is 2.3 x104 m, and
its speed is 4.5 km/s, what is the frequency?
The frequency of the wave is 0.196 Hz
Speed of a waveThe speed of a wave is given by v = fλ where
f = frequency and λ = wavelengthFrequency of the waveMaking f subject of the formula, we have
f = v/λ
Since
v = speed of wave = 4.5 km/s = 4.5 × 10³ m/s and λ = wavelength = 2.3 × 10⁴ m.Substituting the values pof the variables into the equation, we have
f = v/λ
f = 4.5 × 10³ m/s ÷ 2.3 × 10⁴ m.
f = 1.957 × 10⁻¹ Hz
f = 0.1957 Hz
f ≅ 0.196 Hz
So, the frequency of the wave is 0.196 Hz

Is this animal a carnivore or an herbivore? How do its teeth help it obtain food?
Answer:
This animal is a herbivore. The front teeth help it tear off vegetation, and the back teeth help it chew the plants.
Explanation:
A herbivore's back teeth are adapted to help it chew its high fiber plant diet. The front teeth, however, help it actually put the food in its mouth. The picture below shows a typical goat skull (herbivore), and as you can see, it is similar to the one in your problem. So, that skull is one from a herbivore.

How does a comparison of bone structures of two animal provide evidence of an evolutionary relationship
Answer: Comparative Anatomy
Both provide evidence for evolution. Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. These structures may or may not have the same function in the descendants.
Explanation: hope it helps
mark me as brainliest ^_^
Over the course of evolution, the bones of the animals undergo a gradual change in shape as well as in size. But still, two closely related animals have an identical overall layout of the bone.
What do you mean by Evolution?Evolution may be defined as a gradual process that involves changes or modifications in the members of the same or different species over a long period of time.
The bones of descent common ancestors reveal the evolutionary relationships among the animals. In relationship involves homologous and analogous structures.
The homologous structure reveals the structural similarity between the animals, while the analogous structures reveal the functional similarity.

Which statement describes one way that roots and leaves interact to transport water through plants?
The flow of oxygen out of the stomata of leaves
stimulates the roots to absorb more water for
photosynthesis.
Wilting leaves send chemical signals to the roots,
causing them to take in water at a faster rate.
The evaporation of water through the stomata of
leaves creates a pull that draws water in through the
roots.
Changes in sugar concentration in the phloem of
leaves causes water to move into the roots by
osmosis.
The statement that describes one way that roots and leaves interact to transport water through plants is: evaporation of water through the stomata of leaves creates a pull that draws water in through the roots.
What is transpiration?Transpiration is the process whereby water is lost from the surface of the leaf into the atmosphere.
A process called transpiration pull facilitates the absorption of water by the root hairs of the plant.
The water then moves via the conducting vessel called xylem to other parts of the plant.
Therefore, the statement that describes one way that roots and leaves interact to transport water through plants is: evaporation of water through the stomata of leaves creates a pull that draws water in through the roots.

All statements are true about the energy and trophic levels. So, the correct option is D. None of the above.
What are trophic levels?Trophic levels are the levels of energy transfer from lower to higher levels.
There are five levels of trophic level.
The lower level contains autotrophs or producers. And the uppermost level contains big animals or tertiary consumers.
The energy level decreases on going to the higher levels because some amount of energy always lapses as entropy.

How is this unlike making a photocopy of the original dna molecule
Answer:
The process of DNA replication results in a copy of the original DNA molecule. True or false: DNA does not have to break apart to be copied. After DNA replication is complete, there are two new DNA molecules; one molecule has both of the original strands and one molecule has two new strands of DNA.

6. Multiple genes interact to determine the phenotype.
7. Two alleles are dominant, resulting in offspring that show both phenotypes.
8. One gene has several different forms, resulting in more than two phenotypes.
9. Two alleles are neither completely dominant nor completely recessive, resulting in a phenotype that is a combination of the two
Answer:
6.polygenic traits
7.codominance
8.multiple alleles
9.incomplete dominance
Explanation:
because i did it in savvas and i got it right.
The phenotype of an organism is influenced by the interactions of several genes. This implies that the organism's physical traits are governed by the interplay of several genes that it received from its parents.
When two alleles, or gene forms, are dominant, the dominant allele determines the phenotype of the progeny. This means that even if the other gene is recessive, the progeny will exhibit both traits if one of the alleles is dominant.
Sometimes a gene can take on several forms, producing more than two phenotypes. It is referred to as polygenic inheritance when more than one allele of a single gene affects the phenotype. Other times, two alleles are neither fully dominant nor fully recessive.

During light detection in a photoreceptor, light directly causes what molecular change?.
During light detection, the light causes a retinal change from cis to trans conformation in regards to the opsin protein.
What is a photoreceptor?Photoreceptors are the name we use to refer to a specialized form of neuron cells. These cells are crucial in our ability to see, they allow vision. Their job is to receive and interpret light as information. They do this using a protein named opsin, as well as specific conformations of the retina, such as cis or trans, which change with the light.
Therefore, we can confirm that during light detection, the light causes a retinal change from cis to trans conformation in regards to the opsin protein.
