What will happen to the speed of a wagon rolling to the right if the direction of the net force is in the opposite direction to the left?
Answer:
the speed of a wagon rolling to the right if the direction of the net force is in the opposite direction to the left would decrease the speed of the wagon
Explanation:
Answer:
The wagon's speed increases to the left. ... The acceleration of an object moving along a curved path is constantly changing even if the speed is constant, because the direction of the object constantly changes.

Which organelles must work together to provide food and energy to a plant cell?
Answer:
Mitochondria are the working organelles that keep the cell full of energy. In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose.
Chloroplast and mitochondria are organelles that must work together to provide food and energy to a plant cell.
Plants are living organisms that are capable of nourishing themselves from inorganic substances.
The complex chemical process by which they manage to do so is called photosynthesis and it takes place in chloroplasts.
Chloroplasts are elliptical-shaped organelles - their number varies between 20 and 100 in each plant cell - found in leaves and possessing the enzymatic machinery necessary to transform solar energy into chemical energy and, finally, into food.
The plant cell needs energy to grow and multiply and the mitochondria provide most of this energy by performing the last stages of the breakdown of food molecules.
Its main function is to supply the electron carriers (ATP), a product of cellular respiration, which provide the energy that the cell needs.
Therefore, we can conclude that within the leaves of plants, in the chloroplasts of plant cells, the chemical process that transforms inorganic matter into food takes place and the mitochondria are the energy-producing organelles.

A que se denomina metaboismo? Diferenca anabolismo de catabolimo da 4 ejemplos diferencia reaccion endegonica de exergonica
Answer and Explanation:
Metabolismo: El término hace referencia a todos los cambios y las reacciones quimicas y biológicas que ocurren en cada célula del organismo y que resultas escenciales para el funcionamiento adecuado del organismo (una buena nutrición, crecimiento, reparación celular, conversion energética, etc.).
Estas reacciones ocurren a lo largo de toda la vida del organismo. Cada celula toma sustancias que luego modifica químicamente para integrarlas como nuevos componentes celulares. Algunos de estos componentes son utilizados en reacciones como la respiración celular.
El metabolismo puede ser dividido en anabolismo y en catabolismo. Durante el anabolismo suceden reacciones que consumen energía (ATP) para sintetizar moléculas complejas a partir de moléculas simples, y que son necesarias para el funcionamiento del organismo. Mientras que durante el catabolismo suceden reacciones que liberan energía al deegradar o reducir moléculas grandes en otras mas simples, para que el cuerpo pueda asimilarlas y las transforme en energia (ATP). Esta energía luego será utilizada en los procesos anabólicos.
Ejemplos:
- Respiración celular: Degradación de molécula del glucosa para liberar y obtener energía y consecuentemente, moleculas mas simples (CATABOLISMO)
- Ciclo de Krebs: Oxidación de la molécula acetil-CoA y obtención de energía en forma de ATP (CATABOLISMO).
- Digestión: Degradación del alimento para obtener elementos mas asimilables por la célula y energía (CATABOLISMO).
- Degradación de ADN y ARN (CATABOLISMO).
- Fotosíntesis: Transformación de compuestos inorgánicos en orgánicos utilizando energía solar (ANABOLISMO).
- Síntesis proteica: Utiliza aminoácidos y energía para formar proteinas necesarias para el organismo (ANABOLISMO).
- Ciclo de Calvin: Usa moléculas de CO2 para formar glucosa (ANABOLISMO).
- Gluconeogénesis: Síntesis de glucosa a partir de precursores diferentes a los glúcidos (ANABOLISMO).
Reacción excergónica: reacción espontánea que se lleva a cabo y donde se produce la liberación de energía. No necesita energía para suceder.Reacción endergónica: reacción no espontánea. Necesita energía para suceder. Ocurren reacciones celulares a partir del consumo de energía.DNA sequences can act as "tape measures of evolution." Some highly-conserved regions of the human genome (similar to comparable regions in other species) don't code for proteins. Why?
1. Such regions coded for proteins in genomes of distant human ancestors, but over time they became noncoding; however, conserving their sequence remained unchanged.
2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.
3. Such regions are the sites of DNA recombination. They should remain conservative to provide an accurate recombination process during cell division.
4. Such regions remain conservative because the mutation rate differs along the genome. In other words, such regions remain conservative accidentally.
Answer:
2. Such regions play a significant role in gene regulation. That is why they remain conservative under the influence of natural selection.
Explanation:
Within the genome there are many non-coding regions that control the expression of master developmental genes such as, for example, Hox major transcription factors (TFs) in animals and MADS-box TFs in plants. These gene regulatory regions (e.g., promoters and enhancers) are generally evolutionarily conserved within certain taxonomic groups. In consequence, such non-coding regions are well known to be conserved and interact in a sequence-specific manner with major transcription factors in order to regulate developmental pathways.

Match each term to the appropriate description.
Answer:
Have a great day!
Explanation:
The appropriate term for each description would be ecosystem, community, population, organism, and species respectively.
Definition of ecological terms?An ecosystem is a community of all living organisms interacting with their environment as a system.
A community is a collection of different populations of organisms.
A population is a group of organisms of the same species capable of mating.
Species are a group of organisms that is capable of breeding to produce fertile offspring.
Thus, the term for each description would be ecosystem, community, population, organism, and species respectively.

A. thalamus
B. hippocampus
C. brain stem
D. corpus callosum
Answer:
a
Explanation:
The correct answer is C. Brain Stem.
How does the brain stem function?The thalamus and other areas of the brain receive nerve signals from our senses through the brain stem. It is made up of the medulla, pons, and midbrain and is situated at the base of the brain.
The brain stem is in charge of regulating life-sustaining processes including breathing, heart rate, and blood pressure. It is also in charge of transmitting sensory data from the body to the thalamus, which subsequently transmits the data to the relevant parts of the brain.
Although the brain stem is the main pathway for nerve impulses from our senses, the hippocampus, corpus callosum, and thalamus are all important in the processing of sensory information.

Explain how sexual and asexual reproduction both lead to better evolutionary fitness.
Answer:
Hope you get done. friend me back. and can I have brainliest
Explanation:
To get diversity in individuals, genetic differences are required, and different phenotypes must be expressed. Since sexual reproduction is more conducive to driving evolution than asexual reproduction, much more genetic diversity is available for natural selection to work on. Evolution can happen over time.
Ronald observes a sparrow's nest in a shrub outside his home. The table below describes his findings.
Week
Observations
1
Six eggs were laid in the nest.
3
Five eggs hatched, and one egg did not hatch.
One of the chicks disappeared.
7
Three of the chicks learned to fly, and another one disappeared.
What part of natural selection did Ronald observe?
adaptation
overproduction
selection
variation
Answer:
B. Overproduction
Explanation:
Overproduction is one of the main part of natural selection whereby an organism reproduces more offspring, of which only a few would be able to survive given the environmental condition amd factors that would be against the survival of the offspring to maturity.
From Ronald observation, we can see that the bird produces more eggs than would survive. Only 3 of the chicks survived.
