Proceed though meiosis to anaphase 1 . Which chromosomes went up and which went down?
Up : Down :
Answer:
The upper chromosomes went up and lower chromosomes went down.
Explanation:
Anaphase 1 of meiosis, the chromosomes that are present at the upper side went up and move towards the pole while on the other hand, the chromosomes which are located at the lower side went down moves toward another pole. Both chromosomes remain attached to one another in anaphase 1 while in telophase I, the chromosomes arrive at opposite poles of the cell.

When two molecules of glucose (C6H12O6) are combined to form a molecule of maltose (C12H22O11), the formula of the maltose molecule is not C12H24O12 because __________ is formed in this reaction.
Answer:
water(H2O)
Explanation:
2C6H12O6-->C12H22O11+H2O
you can see that the difference between C12H24O12 and C12H22O11 is 2hydrogen atoms and an oxygen atom which are found in the water molecule also through hydrolysis you can bring that molecule of water back and restore two molecules of glucose
C12H22O11+H2O-->2C6H12O6

Which statement about identical twins and fraternal twins is correct in regards to DNA?
A. Identical twins have different DNA, and fraternal twins have different DNA.
B. Fraternal twins share the exact same DNA, but identical twins do not.
C. Identical twins and fraternal twins share the exact same DNA.
D. Identical twins share the exact same DNA, but fraternal twins do not.
Answer:
D. Identical twins share the exact same DNA, but fraternal twins do not.
Explanation:
Identical twins are the twins formed from one egg provided by their mother and one sperm provided by their father. In contrast, fraternal twins are formed from two different sperms and two different eggs from the same father and mother.
Due to the fact that identical twins are as a result of one fertilized egg dividing into two, they share the same exact DNA. On the other hand, fraternal twins do not share the same exact DNA because they are formed from separate eggs and separate sperms.

the amazon rainforest and basin has long been a pristine environment Technology has allowed mankind to reap the natural resources of this area . The removal of these resources has caused what phenomenon to occur
(a) tundra
(b) deforestation
(c) biodiversity
(d) wasteland
Answer:
(b) deforestation
Explanation:
The "Amazon Rainforest" has long been facing a destruction from deforestation. It is even expected to rise in the future because of the advancement in technology. Many deforesters destroy forests in order to promote large-scale agriculture, thereby hastening illegal logging for future projects such as roads and canals. This drives away many animals and put their health and people's health at risk.

construct a process by which rocks may change forms. Rock melts. Sediments deposit into a basin. Magma cools and solidifies underground. Weathering occurs. Intrusive igneous rock forms. Sedimentary rock forms.
Answer:
Las rocas ígneas (del latín ignis, fuego) también nombradas magmáticas, son todas aquellas que se han formado por solidificación de un de material rocoso, caliente y móvil denominado magma; este proceso, llamado cristalización, resulta del enfriamiento de los minerales y del entrelazamiento de sus partículas. Este tipo de rocas también son formadas por la acumulación y consolidación de lava, palabra que se utiliza para un magma que se enfría en la superficie al ser expulsado por los volcanes.
Cuando la solidificación del magma se produce en el seno de la litósfera, la roca resultante se denomina plutónica o intrusiva; si el enfriamiento se produce, al menos en parte, en la superficie o a escasa profundidad, la roca resultante se denomina volcánica o extrusiva y estos, a su vez, se subdividen en familias a partir delas diferentes texturas, asociaciones minerales y modo de ocurrencia. Las formas que adoptan los cuerpos ígneos durante su cristalización delimitan diferentes estructuras ígneas.
Existen diversos criterios para clasificar una roca ígnea, cada uno de ellos con objetivos definidos, como la ocurrencia de las rocas, el tamaño de grano, la textura y estructura, el contenido mineral o la composición química.
Rocas ígneas intrusivas o plutónicas
Son rocas formadas en el interior de la corteza terrestre. Cuando un magma se enfría bajo la superficie lo hace más lentamente, permitiendo un mejor desarrollo de los cristales, que debido a eso alcanzan tamaños que pueden ser observados a simple vista, generalmente abarcan grandes extensiones de terreno y llegan a la superficie terrestre mediante procesos orogénicos (deformaciones tectónicas) o mediante procesos externos de erosión. Dentro de este tipo de rocas, algunos autores reconocen una clase intermedia, la hipoabisal, que incluye a las rocas que han cristalizado a una profundidad moderada y se presentan en forma de filones o diques, rellenando grietas; son mucho menos abundantes que las plutónicas y se encuentran casi siempre asociadas a ellas.
Explanation:
The process of rocks undergoing change includes :
1. Sedimentary rock forms2. Sediments are transported by water.3. Sediments are deposited in a basin.4. Lithification takes place.5. Weathering occurs.6. The rocks are exposed to extreme heat and pressure.7. Rock melts.8. Magma cools and solidified underground.9. Intrusive igneous rocks form.What is a rock cycle?The rock cycle shows us the formation and changes in the nature of the rocks on the surface of the earth and how thet igneous rocks convert into the sediembtary rocks.
How they get transformed into the metamorphic rocks and there but later get recycled back into the igneous type. The rock cycle is thus a dynmaic sequence of the rocks etting trnaofed form one to another.

Which of the following includes an example of each type of symmetry and asymmetry?
jellyfish, sea anemones, and sponges
sponges, jellyfish, and turtles
turtles, jellyfish, and pelicans
sponges, pelicans, and turtles
Answer:
option A IS THE ANSWER : jellyfish, sea anemones, and sponges
Explanation:
IF IT IS CORRECT PLEASE MARK AS BRAINLIEST
The option that includes an example of each type of symmetry and asymmetry is jellyfish, sea anemones, and sponges. Thus, the correct option for this question is A.
What is Symmetry?In biological science, symmetry may be defined as the repetition of the parts in an animal or plant in an orderly fashion. It refers to a correspondence of body parts, in size, shape, and relative position, on opposite sides of a dividing line or distributed around a central point or axis.
There are four types of symmetry that occur among animals: spherical, radial, biradial, and bilateral. While Asymmetry means the absence of symmetry as the body of the organism cannot be divided into parts along any one plane. Jellyfish and sea anemones possess radial symmetry.
Therefore, jellyfish, sea anemones, and sponges represent an option that includes an example of each type of symmetry and asymmetry.

loss of biodiversity is not among the three major categories of environmental problems.
What are environmental problems?Environmental problems are the results of human activities on the biophysical environment, most frequently negative consequences that lead to the degradation of the ecosystem.
They are negative impacts of human activities on the environment. These include environmental issues including pollution, population growth, waste management, and the greenhouse effect, among others.
To achieve a balance between man and the environment, many environmental protection measures are being implemented at the individual, organizational, and governmental levels. Making use of reusable items instead of disposal ones is one of the solutions to environmental issues.
