Answer:
A. Many fossils of Shark teeth have recently been found that are all the same size and color compared to modern sharks.
Explanation:
Evolution is the change in characteristics of a species over time and it relies on the process of natural selection.
The theory of evolution states that all species are related and gradually change over time.
Since all options except A show a change in the characteristics of shark teeth in the fossils found in relation to modern sharks, option A is the answer. Since, there is no change in characteristics between the Shark teeth in the fossils and that of modern sharks.
So, option A is the answer.

Pretend that you are writing a letter to the president proposing ways that the US can reduce its contribution to climate change. In your letter, include at least three facts you learned today.
Answer:
Dear Mr. President,
Your strong voice has called attention to the risks of human-induced climate change and the need to take timely and effective steps to address it. We are pleased to report further progress in our efforts to advise you on climate policy options that could help encourage these steps.
- (Explain what you learned in class today ) I don't know what you were taught in class so you have to figure what to put here.
Mr. President, our temperatures are consistently rising while moisture is increasingly evaporating. Forest management is merely one piece of the puzzle — something our own firefighters would be quick to remind you. Since 2009, our state has spent more than $130 million on forest health and fire preparedness. These events still overwhelm our residents and resources, because these fires are unlike anything people have seen before.

Let's say your name is Gilligan, you've survived a shipwreck and you're stranded on a desert island. You happen to have been stranded with a medical doctor that has a limited stock of medical supplies. One of your shipmates is in desperate need of a blood transfusion but doesn't know his blood type. You do know your blood type. How could you type his blood with your knowledge and limited medical supplies?
Answer:
In order to find the blood type of the shipmate, Gilligan mixes a little blood of the shipmate with himself firstly and than with individual blood types to simplify the data by process of elimination.
Explanation:
There are a total of four types of blood groups which are as follows:
A blood grp has anti B antibodies, has A antigen B blood group has anti A antibodies, has B antigen AB blood group has no antibodies, has A and B antigen O blood group has no antigens, has anti A and anti B antibodiesIn order to find the blood type of the shipmate in the deserted needs of a blood transfusion, mixing of your blood with some of his blood is carred out:
if no clumping seen then the shipmate has same type of blood group as you or has AB blood group (AB has no antibodies). If clumping is seen then person has O blood group(has both anti A and anti B antibodies) or the other type of blood group (that is if Gilligan's blood group is type B, if clumping is seen then the other person's blood group is O or A type because he has anti B antibodies in both of them)PLEASE HELP!!

Which kingdom would a species be classified in if it has a nucleus, cell walls and
chloroplasts, gets energy through photosynthesis, and is an autotroph?
A.Protista
B.Fungi
C.Plants
D.Animals
Answer:
C. Plants
Explanation:
Taxonomy can be defined as the process of naming, classification and description of living organisms such as plants and animals, based on similarities or characteristics e.g eyes, number of legs, etc.,
The eight (8) biological classification (taxonomy) used for grouping and organizing organisms are; Kingdom, Domain, Phylum, Family, Order, Class, Species and Genus.
Additionally, the three (3) domain in which living organisms can be classified are: Bacteria, Eukaryote, and Archaea.
Thus, taxonomy helps scientist to have a good understanding and knowledge when studying various organisms.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In Biology, producers are the living organisms that are capable of manufacturing their own food and as such can provide energy or food for the other living organisms (consumers) in a food chain.
A producer gets energy from the sun and converts it into food. The cells found in producers are capable of converting the energy received directly from the sun into food through a process generally referred to as photosynthesis, converting carbon dioxide from the air, water from the soil, minerals and energy from the sun into organic nutrients.
In the ecosystem, producers are autotrophs or self-feeders such as plants.
Hence, the kingdom in which a species would be classified in if it has a nucleus, cell walls and chloroplasts, gets energy through photosynthesis, and is an autotroph is the plant kingdom (Plantae).
Answer:
C. Plants
Explanation:
Plants are multicellular and most don't move, although gametes of some plants move using cilia or flagella. Organelles including nucleus, chloroplasts are present, and cell walls are present. Nutrients are acquired by photosynthesis (they all require sunlight).

Nombra de forma ordenada el camino que recorre el CO2 desde el capilar sanguíneo que rodea el alveolo hasta salir del cuerpo.
Answer:
El aire ingresa al cuerpo a través de la boca o la nariz y se mueve rápidamente hacia la faringe o la garganta. Desde allí, pasa a través de la laringe o laringe y entra en la tráquea.
La tráquea es un tubo fuerte que contiene anillos de cartílago que evitan que se colapse.
Dentro de los pulmones, la tráquea se ramifica en un bronquio izquierdo y derecho. Estos se dividen aún más en ramas cada vez más pequeñas llamadas bronquiolos.
Los bronquiolos más pequeños terminan en diminutos sacos de aire. Estos se llaman alvéolos. Se inflan cuando una persona inhala y se desinflan cuando una persona exhala.
Durante el intercambio de gases, el oxígeno pasa de los pulmones al torrente sanguíneo. Al mismo tiempo, el dióxido de carbono pasa de la sangre a los pulmones. Esto sucede en los pulmones entre los alvéolos y una red de pequeños vasos sanguíneos llamados capilares, que se encuentran en las paredes de los alvéolos.
Aquí puede ver los glóbulos rojos que viajan a través de los capilares. Las paredes de los alvéolos comparten una membrana con los capilares. Eso es lo cerca que están.
Esto permite que el oxígeno y el dióxido de carbono se difundan o se muevan libremente entre el sistema respiratorio y el torrente sanguíneo.
Las moléculas de oxígeno se adhieren a los glóbulos rojos, que viajan de regreso al corazón. Al mismo tiempo, las moléculas de dióxido de carbono en los alvéolos salen del cuerpo la próxima vez que una persona exhala.
El intercambio de gases permite que el cuerpo reponga el oxígeno y elimine el dióxido de carbono. Hacer ambas cosas es necesario para sobrevivir.
