Answer:
During convection, cooler water or air sinks, and warmer water or air rises. This movement causes currents. These currents move water all around the earth, bringing warm water to cooler areas and vice versa. This redistributes thermal energy and causes changes in the weather.

A beneficial association between coral and algae is an example of
a. commensalism
b. mutualism

The corals and algae have a mutualistic relationship. The coral provides the algae with a protected environment and compounds they need for photosynthesis. In return, the algae produce oxygen and help the coral to remove wastes.
When is the adaptive immune system active?
A All the time
B Only when there's a repeat infection
C Only after pathogens start to multiply
D Only when a person acquires autoimmunity
Explanation:
Adaptive immunity is an immunity that occurs after exposure to an antigen either from a pathogen or a vaccination. This part of the immune system is activated when the innate immune response is insufficient to control an infection

If a population grows by 3 percent each year, the growth of the population is
A. exponential
B. linear
c. cubic
D. logarithmic
Answer:
A. (exponential) population
If a population grows by 3 percent each year, the growth of the population is exponential. Hence, option A is correct.
What is exponential growth?A function called exponential growth depicts an expansion within a population that happens at the same pace across time. If a population doubles or triples in size, you can assume that the data grows exponentially. Exponential decay is the inverse of exponential growth, in which data contracts rather than expands.
Bacteria are one of the best illustrations of exponential growth. Prokaryotic fission is a method of bacterial reproduction that takes around an hour. The population size of 100 bacteria would increase exponentially if we measured it every hour in a certain environment.
The population growth is exponential. Hence, option A is correct.

What can scientists assume about individuals with similar anatomy?
I
Answer:
Scientists compare the anatomy, embryos, and DNA of living things to understand how they evolved.
Explanation:
Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor. Other evidence for evolution is provided by analogous structures
Scientists use anatomy for the study of the evolution of DNA other organs and how they are modified.
Similar anatomy means homologous structure as they provide the information for evolved structure. They provide evolutionary evidence.
What is an analogous structure?
Organisms that have developed alongside special paths may also have analogous systems—that is, anatomical functions which can be superficially just like one another (e.g., the wings of birds and insects). Although such systems serve comparable functions, they have got pretty special evolutionary origins and developmental patterns.
Thus it is clear that scientists assume individuals with similar anatomy for evidence of evolution.

How can pollution reduce the rate of photosynthesis? Research work (60-90 words) unnecessarily,useless answers will be reported
[tex] \huge\mathcal\green{answer}[/tex]
Air pollution has become an extremely serious problem. Air pollutants affect both plants and animals. Under polluted conditions, plants develop different physiological, morphological and anatomical changes. Pollutants cause damage to cuticular waxes by which then they enter the leaves through stomata. This further leads to injury to plants which can be either acute or chronic. Changes in stomata due to air pollutants which seem to be small can be of great consequence with respect to survival of the plant during stress. These effects can further lead to disturbing the water balance of leaf or whole plant. Respiration also gets affected because of the exposure of plants to air pollutants. The present paper deals with the effect of air pollutants on stomata as well as on respiration leading to affect gaseous exchange.

Horticulture 20 points!!!!!A landscape Blank provides organization and labor to install the plants and hardscape elements of a landscape, and may also provide the original design.
Answer:
Explanation:
En su texto, “General Elements and Principles of Landscape Design”, de Melvin Wong, miembro del Departamento de plantas tropicales y ciencias del suelo de la Universidad de Hawai en Manoa, dice que el diseño de paisaje “difiere de otras formas de arte tridimensionales” porque se basa, principalmente, en el uso de formas vivas de color verde que cambian a lo largo del tiempo según su “adaptación, estado nutricional y problemas de plagas”. (1)
Sin embargo, la manera de crear un diseño de paisaje correcto sí combina una serie de elementos de diseño tradicionales como masa, forma, línea, textura, color y otros. En el paisaje, estos elementos se utilizan para transformar el espacio y crear una experiencia única. Si bien el color y la textura agregan interés y riqueza a un diseño, la masa, la forma y la línea son fundamentales para organizar el espacio y proporcionar estructura.

What are the three differences between sugars in DNA and RNA?
De acuerdo al siguiente enunciado, responda: "sus funciones son similares; difieren en su origen embrionario y en su plan de construcción".
Answer:
el enunciado hace referencia a estructuras análogas
Explanation:
La estructuras análogas (por ejemplo, órganos, tejidos, etc) son aquellas que cumplen la misma o similares funciones pero que poseen un origen evolutivo distinto (es decir, no comparten un antepasado común) y son producto de la convergencia evolutiva. Por el contrario, estructuras homólogas son aquellas que se caracterizan por tener un origen evolutivo común (comparten un antepasado común), independientemente de la función que cumplan. Las estructuras análogas se caracterizan por tener diferentes orígenes embrionarios y planes de construcción distintos (es decir, las células que dan origen a este tipo de estructuras son de linajes diferentes). Un ejemplo bien conocido de estructuras análogas son las alas de mariposas y murciélagos, las cuales cumplen la misma función pero no derivan de un antepasado común.
What is the difference in the number of chromosomes found in each cell produced in meiosis compared with mitosis?

b- Cells produced during mitosis have half the number of chromosomes as cells produced in meiosis.
c-Cells produced during meiosis have the same number of chromosomes as cells produced in mitosis.
The cells in our bodies contain 23 pairs of chromosomes - giving us 46 chromosomes in total. Sperm cells and egg cells contain 23 single chromosomes, half the normal number, and are made by a special form of cell division called meiosis. ... Meiosis II divides each chromosome into two copies (much like mitosis).
The packing of chromatin can be regulated by either the acetylation or deacetylation of DNA.

Explanation:
an organisms haploid number if its diploid number is 32?
Answer:
The haploid (n) number would be 23 chromosomes found in the gametes, reproductive cells of sperm and ova. For the organism in this example the diploid (2n) number is 12 making the haploid (n) number would be half of that or 6 chromosomes
Answer:
16
Explanation:
This is because the diploid number of an organism is double the haploid number, therefore 32/2=16
