what structure attaches muscle to bone
Answer:
tendons
Explanation:
A tendon attaches muscle to bone, transmitting the force from the muscle contraction to allow body movement.
Explanation:The structure that attaches muscle to bone is called a tendon. Tendons are made of tough connective tissue and serve to transmit the force generated when a muscle contracts, allowing the movement of the skeleton. For a skeletal muscle to pull on a bone and create movement at a joint, it has specific attachment points; the origin is where the muscle attaches to the fixed (stabilized) bone, and the insertion is where the muscle connects to the bone that gets moved.

asexual reproduction
genes
sexual reproduction
genetic diversity
protists
animals
plants
mammals
Answer:
In asexual reproduction, an organism inherits it's genetic material from a single parent. The new organism has the same genes as it's parent. In sexual reproduction, an organism inherits genetic material from two different parents. Sexual reproduction increases genetic diversity, whereas asexual reproduction does not. Plants, animals, and simple protists, can reproduce sexually or asexually. Mammals only reproduce sexually.
Which of the following is a major function of the cell membrane?
A. To surround and support organelles in eukaryotic cells
B. To receive and send messages between cells
C. To provide rigid support to plant cells
D. To combine amino acids into long chains to make proteins
The major function of the cell membrane is to provide a barrier around the cell, control substance movement via its selective permeability, and facilitate cell communication, making option B ('To receive and send messages between cells') the best answer. Hence the correct option is B.
The cell membrane's structure, primarily made of a phospholipid bilayer, allows it to be selectively permeable, controlling which substances can enter and leave the cell. It is involved in various functions including protecting and supporting the cell, and actively participating in the transport of materials. It also has the important role of facilitating communication and signal transduction, which means option B, 'To receive and send messages between cells,' best describes a major function of the cell membrane. It's also worth noting that the cell membrane encloses the cytoplasm and houses membrane proteins which may vary from one cell type to another, contributing to the diverse functions of the cell membrane in different cellular environments. However, while it does provide some support, option B is a more encompassing choice that includes this function as part of its role in cellular communication and interaction.

Upwelling can be defined as an oceanographic phenomenon in which wind driven motion of dense, nutrient rich, cooler water moves towards the surface of ocean which replaces the nutrient deficient water is replaced.
The nutrient rich water helps in the increasing the growth of the aquatic organism in water.
The nutrient in water allows the plankton to make food at the surface and food is eaten by other organism which helps in a healthier population.
Which characteristic is expected of a mineral that crystallizes from lava at Earth’s surface
Answer:
Small crystals mark me brainiest
Explanation:
i would've passed if he gave me the right answer
A discerning characteristic expected of a mineral that crystallizes from lava at Earth’s surface is that it becomes an igneous rock, like basalt or potentially an amorphous solid like glassy silica if the cooling process is rapid.
Explanation:A characteristic expected of a mineral that crystallizes from lava at Earth’s surface is that it forms an igneous rock. A perfect example of this is basalt, which is produced by the cooling of lava and comprises most of Earth's oceanic crust. If the cooling process is rapid, as with molten silicon dioxide (SiO₂), it can yield an amorphous solid (non-crystalline), known as 'fused silica' or glassy silica.
Basaltic rock is marked by holes left by gas bubbles, a distinctive feature of rock formed from lava. In the case of silicon dioxide, when it cools off from a liquid state, it usually becomes supercooled and turns into a glass, a state characterized by the random arrangement of SiO₄ tetrahedra. This material is highly resistant to rapid temperature changes, which is why it does not fracture easily.

Which of the following are limiting nutrients ?
Water
Carbon
Nitrogen
Phosphorus
Answer:
Nitrogen and Phosphorus
Explanation:
When the function of a whole ecosystem is limited because of a nutrient , which is present in limited amount, it is called as a limiting nutrient. The organisms uptake water and carbon directly from the environment as it is abundant in nature. The nutrients like nitrogen and phosphorous are present in limited amount and moreover they are not present in the form that can be directly taken up by the organism.
Thus, Nitrogen and Phosphorous are limiting nutrients.
What are the dated fossils called that help scientists to identify or date rocks or fossils?
Answer:
Index fossils
Explanation:
The index fossils are the fossils that come in very handy for the geologists when it comes to identifying or dating rock samples or other fossils. The reason for this is that the index fossils have already been dated. They are fossils that are very commonly found, wide dispersed, are easy to be identified, and are limited to only a certain geological period. These characteristics make them an excellent indicator for the dating of the rock layers in which they are found, or the fossils found in the same layers with them, without conducting further examinations.

Which statement about human population growth is least likely to be correct
Answer:
Technological advances in farming and medicine will allow human populations to continue to grow without natural limits.
Explanation:
Technological advances in farming and medicine will allow human populations to continue to grow without natural limits. Thus, the correct option is C.
What is Human population growth?Population growth is the increase in the total number of humans on the Earth. For most of the human history, the population size was relatively stable for time. But with the innovation and industrialization, energy, food, water, and the medical care became more available and reliable.
The logistics population growth has been represented through the help of the logistic growth curve on a line graph and the shape of the curve is a S-shaped curve which represents slow increase, and rapid growth in the population and after which there has been reduction in the growth.
The best example of the logistics growth has been observed in the wild population which has been included in the sheep as well as harbor seals. In both of the cases, the number of population increases and the carrying capacity for small period of time.

What distinguishes bacteria from archaea
Answer:
Archaean cell walls are made up of different compounds than are bacterial cell walls.
Explanation:
I'm doing PBS Learning right now, and this is the correct answer.
Bacteria and archaea differ mainly in cell wall composition, membrane lipids, and genetic material, with bacteria containing peptidoglycan and archaea using pseudopеptidoglycan.
Bacteria and archaea are both unicellular prokaryotic organisms but have several distinguishing characteristics:
Cell Wall Composition: Bacterial cell walls contain peptidoglycan whereas archaeal cell walls do not. Instead, archaea have a substance called pseudopеptidoglycan.Membrane Lipids: Bacteria have ester-linked membrane lipids, while archaea have ether-linked membrane lipids, which can withstand extreme environments.Genetic Material: Although both have circular chromosomes, their genetic sequences differ significantly. Archaea's genetic machinery resembles eukaryotes more than bacteria.complete question:

Answer:
The scientists can attribute structural similarities to common ancestry.
Explanation:
In evolutionary biology, common ancestry or common descent illustrates how an array of species share a most contemporary communal ancestor. There is a huge proof of common ancestry of all forms of life on Earth. The common ancestry in between the organisms of various species originates at the time of speciation, in which establishment of new species occurs from a single ancestral population.

Answer:
E. climax
Explanation:
Even though it is not something that is very common in nature, there are still certain exceptions where certain communities manage to reach a point of equilibrium. This basically is a community of small number of dominant prominent species that create a stable ecosystem. This state of equilibrium is known as climax community. This type of community appears when the web of biotic interactions between the organisms becomes so intricate that there is no possibility of other species to be admitted in it.

Explanation:
Whichever country do we look at, there is a strong relationship between the quantity of energy that the country uses and the size of its economy. The more developed and the larger the economy of a country is, the more energy is demanded for the economy to be driven. This leads to high demand for certain natural resources that produce energy, as the industry needs power in order to function. We can easily see this if we take in consideration the biggest economies in the world, USA, China, Japan, Germany, UK, France, and then if we see how much energy each of them uses, so we will come to a conclusion that the biggest economies are the biggest users of energy.

The process in which plants draw water from their roots to their leaves where it evaporates into the atmosphere is called ____________.

Why is transpiration important for plants?
A. It allows the plant to breathe.
B. It keeps the plant exercised.
C. It keeps plants from getting too dry
D. It helps to regulate their temperature.
Plants control transpiration by opening and closing their _________, which are similar to your ____________ when you perspire
A. leaves; skin
B. stomata; pores
C. flowers; hands
D. capillaries; veins
Answer:
1.D
2.C
3.B
Explanation:
hope this helps
Answer:
1. D
2. D
3. B
Explanation:
The only possible answer for the first question is transpiration because precipitation is essentially rain (and all its forms), condensation is the collection of water, and evaporation is simply water in gas form -- thus making D the "odd one out".
For the second question, we know that transpiration is heavily dependent on stomata/guard cells. Exercise has nothing to do with this topic, and transpiration has very little to do with dryness (which makes B and C incorrect). Finally, plants do NOT breathe through transpiration. Instead, they breathe through plant (cellular) respiration (which eliminates A, leaving only D).
For the third question, we know that stomata/guard cells control a variety of cellular (and extracellular) activities in plants. When the stomata are closed, rates of transpiration decrease due to the inability of water to escape. When they are open, however, rates of transpiration increase and the plant loses more water. The most similar thing to that in the human body would have to be our pores, which open and close in response to stimuli (they release sweat when we're too hot, trigger the production of oils in our skin, etcetera). The other choices do not make much sense; for example, capillaries are used for distributing and receiving supplements from the soil and do not control transpiration.
Use logical reasoning and remember that stomata/guard cells control gas exchange and water loss. I recommend watching Hank Green's videos on plants if you are truly confused.

If 30% of the bases in a particular DNA molecule are guanine(G), what percentage of the bases would be thymine(T)? Explain your reasoning.
Since 30% of the bases are guanine, we know that 30% must also be cytosine (because it pairs with guanine in DNA).
Knowing this, we have figured out 60% out of 100%, leaving us with 40%.
Thymine pairs with Adenine, so Thymine and Adenine each make up 20% of the remaining 40% of the DNA in this example.
In total:
Guanine: 30%
Thymine: 20%
Cytosine: 30%
Adenine: 20%
Percentage of thymine will be 20%
Deoxyribonucleic acid (DNA) is a double stranded molecule and one of the two types of nucleic acids. It is made up of nucleotides subunit namely: Adenine (A), Guanine (G), Cytosine (C) and Thymine (T).Adenine (A) pairs with Thymine (T) while Guanine (G) pairs with Cytosine (C) in the DNA molecule. According to Chargaff in his rule, the amount of all four bases equals to 1 i.e.A + G + C + T = 100% or 1
In a DNA molecule, Adenine = Thymine and Guanine = Cytosine. This means that the amount of adenine and thymine is equal and the same goes for cytosine and guanine. According to this question, If 30% of the bases in a particular DNA molecule are guanine(G). This means that the percentage of its pair (Cytosine) will also be 30%.That is;
A = T + G = C = 100%
A + T + (30 + 30) = 100
A + T + 60 = 100
A + T = 40
T = 40/2 = 20%
Hence, the percentage of thymine and adenine will be 20% each.
An atom has a proton mass of 35, a neutron mass of 35, and an electron mass of 3. What is the estimated mass of the atom.
Answer: Answer choice B . 70 (35 protons + 35 neutrons)
Explanation:
Answer:
The estimated mass of the atom is 70 amu
Explanation:
An atom has a proton mass of 35, a neutron mass of 35, and an electron mass of 3.
Mass of an atom is equal to the sum of number of protons and number of neutrons.
In this case, number of protons p = 35
Number of neutron n = 35
So, the estimated mass of the atom will be :
[tex]M=35\ protons+35\ neutrons=70\ amu[/tex]
Hence, this is the required solution.
