please help me, i dont like this :(
Answer:
This is false.
Explanation:
Plants are eukaryotes, meaning they contain a nucleus in their cells. Prokaryotes, such as bacteria, do not contain a nucleus, and their genetic material, better known as DNA, floats about freely in their cytoplasm.
Can someone help me figure this out please?

NaCl has two elements, Na (sodium) and Cl (chlorine).
C6H12O6 has three different elements, carbon (C), hydrogen (H), and oxygen (O).
NaOH has three elements, Na (sodium), O (oxygen), and H (hydrogen).
Which of the different levels of classification is the most specific?
A. species
B. genus
C. domain
D. class
Answer:
A. Species
Explanation:
Species is the most specific level of classification in taxonomy.
One mnemonic that can be used to remember the order of ranks is:
Dear King Philip Came Over For Good Soup
This stands for domain, kingdom, phylum, class, order, family, genus, species.
And, this is in order of the most broad to the most specific rank.
So, A is the correct answer.
Answer:
the Answer is A
Explanation:
because is you look up the classification levels you will see species is the smallest

D. A formula model shows which atoms are larger but the 3D model does not.
Answer: # 1: c. #2: d. #3: a
Explanation:
#1 is C. because the equation for cellular respiration is C₆H₁₂O₆
+ 6O2 --> 6H20 + 6CO2 + ATP
This says the reactants (inputs) are oxygen and glucose and the products (outputs) are water, carbon dioxide, and ATP. 1 glucose molecule makes 6 carbon dioxide, so 3 glucose would make 18 carbon dioxide molecules.
#2 is D. because the law of conservation of matter states that matter cannot be created nor destroyed, so the weight before and after cellular respiration would stay the same, as the matter would not change.
#3 is A. because a model would show the exact way the molecules would be arranged, while a formula only tells you how many there are, not the way they would be made up.
Hope this helps :)

Answer:
Cuando la célula madre se divide varias veces de forma consecutiva y los núcleos se rodean del citoplasma dentro de ella, es una reproducción tipo: esporulación.
Explanation:
En la reproducción asexual, un solo ser origina nuevos individuos iguales entre si e iguales a su progenitor. Este tipo de reproducción es común en ciertos invertebrados, en las bacterias y en los protozoarios. La esporulación es uno de los tipos de reproducción asexual, esta consiste en varias divisiones del núcleo que se envuelve de fragmentos citoplasmáticos, originando muchos descendientes genéricamente idénticos. Dicha reproducción permite la formación de esporas y la liberación de las mismas cuando las paredes de la célula se rompen. Se observa en ciertas especies de protozoarios.

how is the phloem in a leaf related to the roots of the plant?
a. cells that contain sugar move between the leaf and roots within the phloem. 
b. chloroplasts that make sugar move through phloem cells to the roots. 
c. water in the phloem cells comes to the leaf from the roots. 
d. sugar made in the leaf is carried to the roots by cells in the phloem.
Answer:
The phloem carries important sugars, organic compounds, and minerals around a plant. Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. The phloem is made from cells called 'sieve-tube members' and 'companion cells'.

What property of water allows water
to soak up so much CO2 gas?
Answer:Carbonic acid releases hydrogen ions, which combine with carbonate in seawater to form bicarbonate, a form of carbon that doesn't escape the ocean easily. As we burn fossil fuels and atmospheric carbon dioxide levels go up, the ocean absorbs more carbon dioxide to stay in balance.

Explanation:
Which cell has the GREATEST surface area to volume ratio?
O Chicken egg
O Skin cell
O Bacterial cell
O Liver cell
The cell with the greatest surface area to volume ratio is the smallest cell, in this case, the bacterial cell.
As a cell increases in size, the proportional increase in volume is higher than that of its surface area. This tells us that the bigger a cell becomes, the lower its surface area to volume ratio will be.
The chicken egg is just one large cell, the largest cell produced by most animals. The skin and liver cells are much smaller, measuring roughly 25-30 micrometers. However, the smallest of the list by far is the bacterial cell, measuring a mere 1-3 microns. This size tells us that the greatest surface area to volume ratio belongs to the bacterial cell.

where do convection currents occur.
A. in areas with the same temperature.
B. in areas with the same altitude.
C. in areas with different air pressures
D. in areas with different cloud types.
Answer:
the answer is C-in areas with different air pressures
Explanation:
Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated.
Answer:C. in areas with different air pressures
Explanation:
which of the following is a measure of the force with which molecules in the atmosphere push on the surface?
A. air pressure

Write a statement about the role gravity plays in the motion of the planets.
Answer:
Gravity is what holds the planets in orbit around the sun and what keeps the moon in orbit around Earth. ... Gravity creates stars and planets by pulling together the material from which they are made. Gravity not only pulls on mass but also on light.
how do the villi and microvilli maximize the ability of the intestine to absorb nutrients?
Answer:The function of the plicae circulares, the villi, and the microvilli is to increase the amount of surface area available for the absorption of nutrients. Each villus transports nutrients to a network of capillaries and fine lymphatic vessels called lacteals close to its surface.

Answer:
Inflammation
Explanation:
Innate Response:
"The innate immune system is the body's first line of defense against germs entering the body. It responds in the same way to all germs and foreign substances, which is why it is sometimes referred to as the "nonspecific" immune system. It acts very quickly: For instance, it makes sure that bacteria that have entered the skin through a small wound are detected and destroyed on the spot within a few hours. The innate immune system has only limited power to stop germs from spreading, though. The innate immune system consists of: Protection offered by the skin and mucous membranes AND Protection offered by the immune system cells (defense cells) and proteins."
Acquired Response:
"The adaptive immune system takes over if the innate immune system is not able to destroy the germs. It specifically targets the type of germ that is causing the infection. But to do that it first needs to identify the germ. This means that it is slower to respond than the innate immune system, but when it does it is more accurate. It also has the advantage of being able to "remember" germs, so the next time a known germ is encountered, the adaptive immune system can respond faster. The adaptive immune system is made up of: T lymphocytes in the tissue between the body's cells AND B lymphocytes, also found in the tissue between the body's cells AND Antibodies in the blood and other bodily fluids."
I'm sure it's Inflammation, so here is the definition for that:
"Inflammation refers to your body's process of fighting against things that harm it, such as infections, injuries, and toxins, in an attempt to heal itself. When something damages your cells, your body releases chemicals that trigger a response from your immune system."
