why some fruits have 1 seed and some gruits have many seeds
Answer:
Number of seeds in a fruit depends on the number of ovules in an ovary before fertilizations. The fruits which have more seeds in them have more number ovules in the ovary of flowers such as watermelon and those with single seed have only single ovule in the ovary of flowers like mango
Answer:
Number of seeds in a fruit depends on the number of ovules in an ovary before fertilisation. The fruits which have more seeds in them have more number ovules in the ovary of flowers such as watermelon and those with single seed have only single ovule in the ovary of flowers like mango.
Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, would you expect the pH of the intermembrane space to increase or decrease
Answer:
Increases.
Explanation:
The pH of the intermembrane space increases as the poisoning of cyanide occurs. After cyanide poisoning, the electron transport chain can stop pumping of electrons into the intermembrane space. The pH of the intermembrane space would increase, the pH gradient would also decreases, and ATP synthesis would stop to occur. The pH of the intermembrane space is neutral i.e. 7 but due to cyanide it move towards basic.
Answer:
Cyanide inhibits cytochrome c oxidase, a component of the electron transport chain. If cyanide poisoning occurs, the pH of the intermembrane space becomes more basic. The electron transport chain can no longer pump hydrogen ions into the intermembrane space and ATP synthesis stops.

In these foods, carbohydrates are present in large amount which is a quick source of energy for us. The breakdown of carbohydrates starts from the mouth when the food mixes with saliva which contains an enzyme that starts breakdown of carbohydrates into micromolecules is called glucose that can be absorbed by our body for the production of ATP molecules.
"All honey flora are plants, but all plants are not honey flora". Justify.
Answer:
Beekeeping is affected by adverse climatic conditions and availability of floral resources. This study aimed to survey and characterize the flora in São João do Piauí, a semi-arid region in Piauí, Brazil, and to identify species providing resources to bees. Flowering plants were observed for 18 months, and records were taken of flowering date, growth habit, visitation and resources collected by bees. Melissopalinological analysis of honey produced in the area was performed. A total of 67 flowering plant species were recorded, of which 49 were considered as bee plants, with a predominance of herbs and shrubs. The low rainfall reduces the number of flowering species, which makes important the conservation and multiplication of species which bloom in dry season, such as Ipomoea glabra, Myracrodruon urundeuva, Sida cordifolia and Ziziphus joazeiro, as well as species that contribute to honey production such as Mimosa tenuiflora, Mesosphaerum suaveolens and Croton sonderianus.

Earth’s continents are constantly in motion because they sit on top of gigantic plates which float on Earth’s mantle. Energy from the Earth’s core creates convection currents in the molten layer, and the currents move the plates. Over extremely long periods of time, this movement creates new _______.
a.
biomes
b.
plates
c.
atmospheric layers
d.
elements
Answer:
a. biomes
Explanation:
Ecology can be defined as the scientific study of the relationship between living organisms such as plants and animals in relation to their physical and biological environment.
An ecosystem can be defined as the natural living habitats of both living and non-living organisms, in which they interact with one another. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.
Generally, the different continents on Earth are in a constant motion due to the fact that they're sitted on top of gigantic plates floating on Earth’s mantle.
Furthermore, the Earth’s core generate energy which also creates convection currents in the molten layer of the Earth, thereby, moving the plates.
Over an extremely long periods of time, the movement of these plates create new biomes.
In Ecology, a biome can be defined as a relatively distinct terrestrial region which is made up of animals, micrograms and plants, and it is typically characterized by similar environmental factors such as wind, relative humidity, rainfall, temperature, etc., irrespective (regardless) of where it occurs in the world.
There are five (5) main types of biomes and these are;
I. Forest.
II. Aquatic.
III. Desert.
IV. Grassland.
V. Tundra.

It is difficult to define Primates according to the presence or absence of certain distinguishing anatomical or behavioral traits. What *really* defines Primates is that they all are descended from a single common ancestor approximately 65 million years ago.
Answer:
The correct answer is - true.
Explanation:
Primates are the third diverse group of mammals after rodents and bats. It is considered that it has diverged from other terrestrial mammals about 65 million years ago.
Defining and identifying the primates on the basis of certain anatomical and behavioral traits is not an easy task. There are almost 400 living species of primates are known.
why animal-like organisms did not appear on Earth until after the first
organisms that could photosynthesise had appeared.
Answer:
800 million years ago , these clusters of specialized, cooperating cells eventually became the first animals, which DNA evidence suggests evolved around that time. Sponges were among the earliest animals.

Explanation:
does the presence of introns exons in eukaroytic cells provide more potentia diversity in gene products than is possible in porkatroi cells
Answer: Yes. Splicing can be done in different ways to yield different mRNAs wich will create different proteins. Prokaryotes are not able to do this.
Explanation:
DNA (deoxyribonucleic acid) is a molecule that contains the genetic information for synthesizing amino acids that form proteins. To do this, DNA must first be transcribed into RNA (ribonucleic acid) and this is the molecule used for protein synthesis (translation). The newly transcribed RNA (called primary messenger RNA) from DNA results in a very long molecule and also has regions that do not code for anything, called introns, which are removed by a process called splicing. Exons are segments in the RNA that do code for amino acids and remain in the mature mRNA after splicing.
Splicing is a process by which introns are cleaved from the primary messenger RNA and exons are joined to generate mature messenger RNA. In addition, alternative splicing occurs which allows different mRNA isoforms and thus different proteins to be obtained from a primary mRNA transcript. This is because the exons will be joined or spliced in different ways, giving rise to different mature messenger RNA sequences. This process occurs mainly in eukaryotes, although it can also be observed in viruses. But it does not take place in Prokaryotes (Bacteria).
In summary, exons/introns can be spliced together in different ways to yield different mRNAs sequences. Each different mRNA sequence will code for a different protein.

Select the correct answer from each drop-down menu. Study the graphs, and then complete the passage. An anomaly in global temperature is a deviation from what is normal or expected. The graph shows that global atmospheric co2 ___(increased exponentially. Remained constant. Increased slightly)in the twenty-first century, and global temperature also increased during the same time. Based on the timeline, these statistics suggest a correlation between climate change and ___(wind energy production. Use of electric cars. Industrial carbon emissions). If the current trend of increasing co2 levels continues, the greenhouse effect will continue to ___(warm the planet. Release gas into space. Destroy carbon dioxide) .
Answer:
Increased exponentially
Industrial carbon emission
Warm the planet
Explanation:
The rapid increase in global CO2 in the 21st century has raised concerns over the lingering effect of global climate change which could result due to the exponential increase in CO2 emission at this time. This rise in global atmospheric CO2 has been observed to have a positive relationship with the level of industrial carbon emission. The rise in emission of industrial carbon has been tipped to be responsible for the exponential rise in global atmospheric CO2. CO2 is a form of green house gas responsible for warming the planet.

How many capillary beds must a red blood cell pass through to move from an artery in the left arm to the left ventricle of the heart
Answer:
two capillary beds
Explanation:
Capillary beds are networks of capillaries that supply blood to the organs and/or areas of the body, in which nutrients and gas exchange (i.e., O2 and CO2) between red blood cells and tissues take place. Smaller arteries (i.e., arterioles) diverge into capillary beds composed of 10 to 100 capillaries, the smallest blood vessels in the body that connect the arterioles and the venules. Red blood cells usually flow into a capillary bed from a metarteriole (i.e., a microvessel that connects arterioles and capillaries). Red blood cells sometimes pass through two capillary beds before reaching the heart. The left heart ventricle is a muscle required for pumping red O2-rich blood out through the aortic valve into the aorta, whereas arteries are large blood vessels that branch into arterioles in order to carry blood to the capillary beds.
10 differences between animal cells and plant cells
Answer:
Following are the difference to the given question:
Explanation:
Plant cells have a wall of a cell, while cells of animals wouldn't. Cell membranes offer plants support and shape.Chloroplasts in plant cells do not occur, however, in animal cells. Chloroplasts allow plants can grow things via photosynthesizing.Plant cells typically get a vacuole(s) that is one or even more big, whereas animal cells are vacuous, whether any.Large vesicles assist shape the plant and enable food and water to be store for future use.In animal cells, the storing function takes a smaller part and the vacuoles, therefore, are smaller.A plant cell is square in its structural way and an animal cell is often spherical and irregular.The cell of a plant has a vesicle in its big form which is significantly smaller than the plant cell, as well as the animal cell was the or more vacuoles. In general, a vacuole is a storage area for the cells to store water.There is no chloroplast inside the animal cell. Chloroplast is a plant cell that produces photosynthesis from its food. The plants have a green color.The nucleus is located throughout the cell of the plant on the other edge of the peripheral cytoplasm, while the nucleus is in the animal's core.Plant cells store food of starch while animal cells store food of glucose.The mitochondria in the plant are fewer and also have tube cristae, whereas the animal cells have grown in various.¿Cuál es la molalidad de una disolución al mezclar 4 kg de agua como disolvente con 0,5 Mol de ácido clorhídrico (HCl) como soluto?
Answer:
La molalidad de la disolución es 0,125 molal.

En la teoría de las disoluciones químicas, la molalidad se define como la cantidad de moles del soluto dividida por la masa de solvente, entonces tenemos que la molalidad de la disolución descrita en el enunciado es:
[tex]m = \frac{0,5\,mol}{4\,kg}[/tex]
[tex]m = 0,125\,m[/tex]
La molalidad de la disolución es 0,125 molal.
Which of the following statements describes the conditions of a pneumothorax? View Available Hint(s) Which of the following statements describes the conditions of a pneumothorax? The intrapulmonary pressure equalizes to atmospheric pressure. Both lungs partially or completely collapse. The intrapleural pressure decreases. The presence of air in the pleural cavity.
Answer:
The presence of air in the pleural cavity
Explanation:
A pneumothorax occurs when air builds up between the lung and the chest wall. In consequence, pneumothorax occurs when air gets into the pleural cavity (i.e., the space between the lung and the chest wall) and causes a fully and/or partially collapsed lung. Some of the most common symptoms of pneumothorax include shortness of breath (respiratory distress), rapid breathing, rapid heart rate, fatigue, agitation, dry cough, etc. Pneumothorax can be caused by a chest injury, an accident during a medical procedure, damage from underlying lung diseases, etc.
Most body water comes from:moisture absorbed through the skin.fluids we drink.the food we eat.metabolism.
Answer:
fluids we drink.
Explanation:
Most body water comes from fluids we drink such as water, juices etc. Our body obtains water by absorbing it directly from the digestive tract. A small amount of water is produced in the metabolism of food particles. Our body loses excess amount of water by excreting it in the form of urine from the body. Kidney is the organ that filters waster materials and excess water from the blood and remove it from the body.
