Answer:
A vertebrate is an animal with a spinal cord surrounded by cartilage or bone. The word comes from vertebrae, the bones that make up the spine. Animals that are not vertebrates are called invertebrates. Vertebrates are adapted to life underground, on the surface, and in the air. They feed upon plants, invertebrate animals, and one another. Vertebrate faunas are important to humans for food and recreation.Vertebrate Classes
Agnatha (Jawless Fish) Aves (Birds) Amphibia (Amphibians) Chondrichthyes (Rays, Sharks, Skates) Mammalia (Mammals) Osteichthyes (Bony Fish) Reptilia (Reptiles)

Explanation:
Darwin’s finches evolved on an island. What is the main reason that islands often provide good examples of evolution?
Answer:
They allow for automatic biogeographic isolation. In rock layers, jellyfish fossils are found lower than trilobite fossils, and trilobite fossils are found lower than ammonite fossils.

What does it mean to say science is a systematic process
write paragraph about digestion of food in brief
Answer:
Digestion is the breakdown of large insoluble food molecules into small water-soluble food molecules so that they can be absorbed into the watery blood plasma. In certain organisms, these smaller substances are absorbed through the small intestine into the blood stream.
Explanation:
according to wikipedia!
Digestion is nothing but breaking down of substances into simpler forms, which the body can use. We eat many things and they have very complex compounds, our body cannot use these compounds. So, different parts of our digestive system breaks down different compounds to simpler forms, so that our body can use it for different functions.
Describe sea turtle populations during the late 1400’s
Answer:
6.5 million sea turtles
Recent estimates show us that there are nearly 6.5 million sea turtles left in the wild with very different numbers for each species, e.g. population estimates for the critically endangered hawksbill turtle range from 83,000 to possibly only 57,000 individuals left worldwide.

what bond is broken when energy is released?
Answer:
Bonds are both broken and made in chemical reactions but many biology teachers and textbooks state that "Breaking ATP bonds releases energy." In reactions bonds are broken and made. If the strength of the bonds formed exceeds the strength of the bonds broken the reaction is exothermic.
Explanation:
Hope this helps. :)
A researcher crossed two plants, and informed an assistant researcher to determine the genotypes and phenotypes of the plants that were crossed by analyzing the offspring.

a. The researcher had selfed a true-breeding plant with green pods.
b. The researcher had crossed true-breeding plants of differing pod colors.
c. The researcher had crossed two heterozygous plants.
d. The researcher had crossed two plants with yellow pods.
e. The researcher had crossed a plant with green pods to a plant with yellow pods.
Answer:
c. The researcher had crossed two heterozygous plants.

Answer:
these r so many which one?
Explanation:
What are carbohydrates?
O Water is non-polar which is why other compounds will dissolve in it
O Macromolecules composed of amino acids
O Non-water soluble macromolecules with a high proportion of hydrocarbons
O Macromolecules composed of nucleotides
Answer:
O Non-water soluble macromolecules with a high proportion of hydrocarbons
Explanation:
Carbohydrates are one of the four biological molecules in nature (asides from proteins, nucleic acid, and lipids). Carbohydrates are a complex polymer consisting of several chains of carbon and hydrogen (hydrocarbons).
According to this question, carbohydrates are non-water soluble macromolecules with a high proportion of hydrocarbons.
Natural selection was acting on the population of radish plants. Which of the following DOES NOT satisfy a condition of natural selection as it relates to our radish populations?
a. there was a purple phenotype and a white phenotype
b. the R allele produced a white plant, and rr produced purple plants
c. competition was affecting the reproductive success of at least one of the morphs
d. our populations of radishes were small
e. all of the above are examples of conditions necessary and sufficient for evolution by natural selection
Answer:
d. our populations of radishes were small
Explanation:
Natural selection is a type of evolution that allows only individuals with favorable characteristics and better adapted to the environment to survive and reproduce offspring with the same favorable characteristics. In this case, to observe a population where natural selection is taking place, population sizes can be disregarded, as this is not a condition for natural selection to take place. However, the other conditions presented in the response options are necessary for natural selection, since it is necessary that there are different phenotypes and genotypes in the population and that competition between them promotes the survival of one group at the expense of the other.

Explanation:
Comb jellies are:____.
A. Bilaterally symmetrical.
B. Similar to a cnidarian polyp.
C. Distinguished by eight bands of cilia.
D. Colonial animals.
E. Carnivores that use nematocysts to capture prey.
Answer:
C. Distinguished by eight bands of cilia.
Explanation:
Ctenophora, also known as comb jellies, represents a phylum of transparent, mostly pelagic, invertebrate marine animals that live around the world. This group characterized by eight rows of cilia (singular cilium) that are used for locomotion. Cilia are organelles and/or structures that extend from the surface of eukaryotic cells, which can be used to move the surrounding fluid, resulting in cell movement. This phylum is divided into two classes: Tentaculata (with tentacles) and Nuda (without tentacles).

Ari drew a diagram to show organisms in an ecosystem.
A flowchart. Cycle 1: 1, Grass. 2, Grasshopper. 3, Shrew or Mouse. 4, Fox. Cycle 2: 1, Grass. 2, Mouse. 3, Fox or Snake. Cycle 3: 1, Grass. 2, Rabbit. 3, Fox.
What did Ari draw?
a food chain
a trophic chain
a food web
an energy web
Answer: Ari draw a food web.
Explanation:
A single ecosystem which contains all the food chains is called a food web.
In a food web each living thing present in a food web is a part of multiple food chains. Hence, food webs tend to represent the overlapping of food chains in that ecosystem.
The flow chart drawn by Ari represents that the living things present in cycle 1 are part of cycle 2 and cycle 3. Also, living things present in cycle 2 are part of cycle 1 and cycle 3.
A food chain is basically a single path where each organism is dependent of the other as a source of food without any overlapping.
Thus, we can conclude that Ari draw a food web.
