Name three different cells in a leaf that contain chloroplast. Please help
The LEAF as a photosynthetic organ includes the following cells which contains CHLOROPLASTS
• the palisade mesophyll
• the spongy mesophyll and
• the stomatal guard cells
The LEAFS are the main organ of photosynthesis. Photosynthesis is the process by which green plants manufacture their food in the presence of sunlight. This takes place in the CHLOROPLASTS of these plant. CHLOROPLASTS are structures that contains chlorophyll which traps in energy from the sunlight.
The mesophyll tissues are located between the upper and the lower epidermis of the leaf. The palisade mesophyll, which is found at the upper part, contains numerous CHLOROPLASTS and is the main site of photosynthesis in the leaf.
The spongy mesophyll is located at the lower part of the epidermis. They are irregularly arranged with air spaces between them which are linked to the stomatal openings. They also contain CHLOROPLASTS.
The stomatal guard cells are a pair of bean-shaped cells which controls the opening and closing of stomata. These cells contains CHLOROPLASTS which contributes to the movement of stomata.
Therefore the three different cells of the leaf that contains CHLOROPLASTS are the palisade mesophyll, the spongy mesophyll and the stomatal guard cells.

A pea plant is heterozygous for both seed shape and seed color. S is the allele for the dominant, spherical shape characteristic; s is the allele for the recessive, dented shape characteristic. Y is the allele for the dominant, yellow color characteristic; y is the allele for the recessive, green color characteristic. A pure bred plant with green spherical shaped seeds is crossed with a pure bred plant with yellow dented shaped seeds. State the phenotype and genotype for the parent plants p1 and p2
Answer:
The correct answer is -
P1: SSyy
p2: ssYY
Explanation:
In the given question it is given that S is the allele for the dominant trait of spherical shape over s allele of dented shape and similarly Yellow pea seed is dominant over y green seed.
It is given that parent 1 or p1 is true breeding for green spherical shaped seeds which means it has two alleles of the same gene that are SSyy (S for spherical and y for green) and parent 2 or p2 is a pure bred plant with yellow dented shaped seeds that would be ssYY.

Currently, two of the living elephant species (X and Y) are placed in the genus Loxodonta, and a third surviving species (Z) is placed in the genus Elephas. Assuming this classification reflects evolutionary relatedness. Draw the most accurate evolutionary tree.
Answer:
Explanation:
The evolutionary tree is composed of,
Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches ⇒ Elephant species X, Y, Z Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor ⇒ The red spot in the graph shows the location o the most recent ancestor between species X and Y Root → This is the older common ancestor that all lineages share. The first one in the tree ⇒ The blue spot in the graph show the oldest common ancestor shared by the three speciesTwo or more lineages are more related to each other if they share a recent common ancestor -In this example, X and Y are more related to each other-. This means that they all diverge from the same node.
Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.

3-facilitated diffusion: ions move through the
membrane facilitated by transport/carrier proteins
Suggest why most plants die very quickly if their roots are cut off
Answer:
because plants are living things, and so if someone cuts you in half, then you're most likley gointnto die pretty quick. HOWEVER.... ur body will still most likley be moving because of adrenaline and left over energy.
Answer:
They wouldn't be able to absorb water and other nutrients from the ground if their roots were cut off.
Microbes vary in their tolerance of and requirements for oxygen. While obligate aerobes require oxygen to survive, other microbes can be killed by oxygen. H. pylori is considered a microaerophile as it grows best in a low oxygen environments, which is consistent with the environment in the stomach. What type(s) of microbe is/are likely to be found in the following locations of the body
Hi. Unfortunately, you did not submit the parts of the body to which the question refers, which makes it impossible for it to be answered. However, I will try to help you as best I can.
Microorganisms can be aerobic or anaerobic. Aerobics are those that survive in the presence of oxygen and therefore may be present in parts of the cup that have contact with oxygen. Anaerobic organisms are those that do not survive in the presence of oxygen and therefore can only be present in places in the body that do not come into contact with oxygen.
In this case, to answer your question, you need to identify if the parts of the body, that your question presents, come into contact with oxygen or not. This way it is possible to inform if the microorganisms that these parts of the body have are anaerobic or aerobic.

¿Cuál es el rol de la genética microbiana en el contexto de la Biología?
¿Qué aplicaciones tiene la Genética Microbiana hoy en día?
¿En qué consiste el protagonismo de la Genética microbiana en el devenir histórico de la Biología?
Answer:
- La genética microbiana ha sido fundamental para la comprensión de diferentes mecanismo genéticos y evolutivos
- Los microrganismos son ampliamente utilizados en medicina y procesos biotecnológicos
- La microbiología ha permitido descartar la teoría de la generación espontanea (anteriormente aceptada en biologia) como así también formular nuevas teorías (hoy en día ampliamente aceptadas por la comunidad científica)
Explanation:
La genética microbiana juega un papel fundamental en biología, ya que los organismos microscópicos (por ejemplo, bacterias) poseen características únicas para el estudio de mecanismos genético/moleculares tales como, por ejemplo, 1-un corto tiempo generacional y 2-la capacidad de manipulación de un número de organismos muy alto (N muestral) en un laboratorio. En consecuencia, los microrganismos permiten estudiar mecanismos genéticos y evolutivos con mayor grado de precisión y versatilidad al ser comparados con organismos pluricelulares. La microbiología ha permitido el desarrollo de técnicas esenciales en el campo de la biología molecular: la técnica de edición genómica CRISPR-Cas9 se basa en el sistema adaptativo que poseen ciertas bacterias para hacer frente a infecciones virales. La biotecnología microbiana ha permitido también desarrollar diferentes tipos de alimentos y procesos biotecnológicos (por ejemplo, la cerveza y ciertos productos lácteos requiere la utilización de microrganismos para llevar a cabo el proceso de fermentación). Por otra parte, mediante técnicas de recombinación genética podemos explotar las características de los microrganismos para producir a gran escala ciertos productos biotecnológicos y medicinales (por ejemplo, producir insulina para uso humano). La microbiología emergió en la segunda mitad del siglo XIX y desde entonces ha posibilitado el desarrollo de importantes avances para el tratamiento y cura de enfermedades infecciosas, como así también descartar teorías tales como la generación espontánea y generar nuevos conocimientos en el campo de la biología y la genética (por ejemplo, el descubrimiento que el ADN se replica de manera semiconservativa fue realizado utilizando cepas de E. coli).
Describe the biome in which you currently live, or one in which you want to live, or have lived. What are the atmospheric conditions (wind pattern, humidity level, etc), solar intensity, and geographic/oceanographic features that have produced this unique ecosystem
Answer:
Southern Texas
Explanation:
The Wind pattern often is represented by the westerlies, which are the winds that flow in the northern latitude of the world. The humidity level in this zone varies from 10-20%, since we are in the desert we do not have much humidity, the solar intensity is high, often found in the 9-10 uv range, it is not advised to spend more than 10 minutes on direct sun without solar protection. We have the Rio Grande to the south and some spare mountains.
Answer:
Southern Texas
Explanation:
wich of the following processes takes place during prophase
Answer:
