Consider a cube with length 3cm and another with length 4cm,which of the two cubes will have a a greater surface area volume ratio
Answer:
Cube with length 4cm.
Explanation:
The surface area of cube is 6a^2.
For cube with length 3
A= 6a^2
A= 6 ×(3×3)
=6(9)
= 54cm
For cube b.
A=6(a^2)
= 6×(4×4)
6(16)
= 96cm

Qué es el fotoperiodo y que los ritmos circadianos? y explica cómo afectan a las plantas
Answer:
El fotoperiodo es el fenómeno por el cual las plantas regulan procesos fisiológicos y/o desarrollo de acuerdo a la cantidad de horas luz diarias
Los ritmos circadianos refieren regulación de las funciones vegetales de acuerdo a un reloj interno configurado por la actividad biológica del organismo dentro de un período de 24 horas
Explanation:
El fotoperiodo vegetal refiere a la regulación de los procesos fisiológicos en función de las horas de luz diarias. Por citar un ejemplo, el trigo posee mecanismos fisiológicos los cuales especifican cuando la inflorescencia o espiga debe emerger en función del fotoperiodo, es decir, de la cantidad de horas luz diarias. Por otra parte, un ritmo circadiano es un reloj biológico que marca el ritmo en el cual se desempeñan las funciones biológicas del organismo dentro de un período de 24 horas. En ausencia de estímulos ambientales, las células poseen un reloj biológico/circadiano el cual especifica que actividades metabólicas debe desarrollar en un periodo de 24 horas. Los ritmos circadianos se encuentran en todos los organismos vivos, desde procariotas (por ej., bacterias) hasta eucariotas (por ej., plantas y animales). Por ejemplo, en vegetales, el ritmo circadiano controla la velocidad de la división celular y el crecimiento celular en función de la hora del día (ciclos diurno y nocturno).

The answers to the blank spaces are numbered as follows:
1. Function
2. Nucleus
3. Mitochondria
4. ATP
5. Chloroplast
6. Glucose
7. Ribosomes
Explanation:
This question is describing the organelles found in a cell. An organelle is a structure that performs a specific FUNCTION (1) in a cell. There are different kinds of organelles with each possessing its own peculiar function. Some of them are as follows:
- NUCLEUS, which is regarded as the brain of a cell because it directs or controls a cell's activities just like the brain of an organism does.
- MITOCHONDRIA is an organelle that produces the energy storing compound called ATP (adenosine triphosphate), hence, it is called power house of the cell.
- CHLOROPLAST is an organelle found in plant cells that functions in the conversion of light energy (from sun) into GLUCOSE (chemical energy) in a process called PHOTOSYNTHESIS.
- RIBOSOMES is an organelle found in both prokaryotic and eukaryotic cells that serves as the site of PROTEIN production in a cell.

if you were traveling to a tropical country, why do you think its good to understand about protozoans?
Answer:
Protozoans can be parasitic. Malaria is the most significant of the protozoan parasites that infect humans. Malaria is found in tropical and sub-tropical regions of the world. In addition, tropical countries are often affected by poverty, poor sanitation, and inadequate medical facilities. These factors often increase the transmission of parasitic diseases.

Answer:
1. Non-living
2. Reproduce
3. Nucleic acid
4. RNA
5. Protein
6. Capsid
7. Burst
8. Lytic
9. Lysogenic
Explanation:
Viruses are set of organisms classified as NON-LIVING (1) because they do not exhibit the characteristics that living things exhibit. Viruses are incapable of REPRODUCING (2) on their own, and hence, need a living host to infect in order to replicate itself.
In the structural composition of a virus, it is made up of only one type of NUCLEIC ACID (3), which can either be DNA or RNA (4). The nucleic acid is surrounded by a PROTEIN (5) coat called CAPSID (6).
There are two ways a virus can infect its host. First, it can replicate itself causing the host cell to BURST (7) or lyse in a process called LYTIC CYCLE (8). Also, the virus can remain dormant in the host cell and continually replicate with the host cell in a process called LYSOGENIC CYCLE (9).

How does the entire nervous system allow our bodies to interact with our world? Your response must include the following terms:
peripheral nervous system
central nervous system
sensory neurons
motor neurons
Thank you
Answer:
The nervous system takes in information through our senses, processes the information and triggers reactions, such as making your muscles move or causing you to feel pain. For example, if you touch a hot plate, you reflexively pull back your hand and your nerves simultaneously send pain signals to your brain.
Explanation:
Answer:
I found that on the web hope it helps
Explanation:
"The central nervous system includes the brain and spinal cord, while the peripheral nervous system includes all of the nerves that branch out from the brain and spinal cord and extend to other parts of the body including muscles and organs. Each part of the system plays a vital role in how information is communicated throughout the body."

Which cross section best shows the formation of sedimentary rock?
Answer:
Option 1
Explanation:
The way the layers stack on each other is a obvious example of sedimentary rock.The sediments form layers on top of each other over time that hardens into rock creating layers. Geologists use these layers to determine how old something is or what time period a fossil was from. The sediments form layers on top of each other over time that hardens into rock creating layers.

how many body openings do comb jellyfish have A 0 B 1 C 2 D3
Answer:
C 2
Explanation:
They have two (2) holes. While true jellies have a sealed bell with only one opening (like the one opening of an anemone), comb jellies have a small opening at the top of their body and one at the bottom so that water can flow through them. - They often have plates for protection on the outside of their bodies.

20. A specific aphid is known to infest spinach, peppers, and tomatoes. How could a farmer use biological control to reduce aphids on these crops?
O A. Apply neem oil to the crops
O B. Introduce ladybugs to eat the aphids
O C. Introduce honeybees to pollinate the crops
D. Only plant crops that produce the Bt toxin
Answer:
O B. Introduce ladybugs to eat the aphids
Explanation:
In crop production, there are certain pests known to categorically affect a particular crop plant. Hence, there are ways devised to tackle this issue of pest attack on crops. One of those ways is the "BIOLOGICAL CONTROL METHOD".
The biological control method involves the use of natural enemies to combat pest organisms. The natural enemies are living organisms that prey on the so called pest organism. This is the case in this question, where a specific aphid is known to infest spinach, peppers, and tomatoes.
The farmer will employ biological control method in stopping these aphids by introducing ladybugs to eat the aphids.

How are traits passed from generation to generation? Explain how dominant and recessive alleles interact to determine the expression of traits.
Answer:
Genes come in different varieties, called alleles. Somatic cells contain two alleles for every gene, with one allele provided by each parent of an organism. ... However, an allele that is hidden, or not expressed by an organism, can still be passed on to that organism's offspring and expressed in a later generation.
The traits are passed from generation to generation through genes. The process is called heredity.
What is the passing of traits?Heredity refers to the specific ways by which features or traits are passed down through generations via genes. Genes contain the instructions for producing certain proteins, which are responsible for an individual's unique characteristics.
Alleles are distinct variations of genes. Somatic cells contain two alleles for each gene, one from each parent of an organism.
An allele that is hidden or not expressed by an organism, on the other hand, can be passed on to that organism's descendants and expressed in a subsequent generation.
Therefore, traits are passed down from generation to generation via genes. The process is known as heredity.
