How does the seed of a gymnosperm differ from the seed of an angiosperm?
Answer:
The key difference between angiosperms and gymnosperms is how their seeds are developed. The seeds of angiosperms develop in the ovaries of flowers and are surrounded by a protective fruit. Gymnosperm seeds are usually formed in unisexual cones, known as strobili, and the plants lack fruits and flowers.
Answer:
Angiosperm seeds develop in the ovaries of flowers and are covered with a protective fruit. Gymnosperm seeds are typically formed in something called strobili, and the plants doesn't have fruit and flowers.

What must be the genotype?
Answer:
XnY
Explanation:
II-2 is a male so the genotype must have a Y in it. Majority of the other options do not have Y, so they are incorrect. Because the individual is male, the father has passed a Y chromosome, while the mother has passed an X chromosome. The X chromosome is Xn because the mother is hemolytic, which is a recessive trait. So both the mother's X chromosomes carry the hemophilia trait.

Look online and find out what each muscle group does and what at least 5 muscles do and list that information.
Flexor Group-
Peroneal Group-
Hamstring Group-
Gluteal Group-
Quadricep Group-
Extensor Group-
Sartorius Group-
Adductor Group-
Answer:
Flexor Group- group of five muscles mainly in charge of movements of forearm, hand and fingers.
Peroneal Group- these muscles play a role in the movements of the ankle joint and support of the foot.
Hamstring Group- The hamstrings are a group of muscles and their tendons at the rear of the upper leg. They include the biceps femoris, semitendinosus, and semimembranosus. The hamstrings flex the knee joint and extend the thigh to the back side of the body.
Gluteal Group- The gluteal muscles are a group of three muscles which make up the buttocks: the gluteus maximus, gluteus medius and gluteus minimus. The three muscles originate from the ilium and sacrum and insert on the femur.
Quadricep Group- The Latin translation of 'quadriceps' is 'four headed,' as the group contains four separate muscles: the vastus lateralis, vastus medialis, vastus intermedius, and the rectus femoris. Each of the vastus muscles originates on the femur bone and attaches to the patella, or kneecap.
Extensor Group- The superficial extensors of the forearm are a group of six muscles situated in the superficial posterior compartment of the forearm. These muscles include the brachioradialis, extensor carpi radialis longus, extensor carpi radialis brevis, extensor digitorum, extensor carpi ulnaris and extensor digiti minimi.
Sartorius Group- couldnt find anything
Adductor Group- The adductors are a group of muscles, as the name suggests, that primarily function to adduct the femur at the hip joint. Although they are all located somewhere along the medial side of the thigh, they originate in different places at the front of the pelvis.

a cell that was unable to produce rna polymerase would not be able to undergo...
a: replication
b: mitosis
c: transcription
d: translation
Answer:
c: transcription
Hope it helps ❤️
A cell that was unable to produce RNA Polymerase would not be able to undergo transcription. So, the correct option is C.
What is Transcription?Transcription is defined as the process by which a cell makes an RNA copy of a piece of DNA where the RNA copy is known as messenger RNA (mRNA) which carries the genetic information needed to make proteins in the cell. This process moves information from the DNA to the cytoplasm in the nucleus of the cell, where proteins are made.
Transcription is carried out by enzymes known as RNA polymerase which add nucleotides to form an RNA strand using the DNA strand as a template. A cell that was unable to produce RNA Polymerase would not be able to undergo transcription.
Therefore, the correct option is C.

Explain why the human population must seek balance between the need for food and environmental protection
Answer: Because currently the type of human food and the way it is produced, damages the environment of our planet. And if this continues, we will reach an irreversible point where we will destroy the only planet we have to live on.
Explanation:
Humans need to eat a varied and balanced diet, so a correct diet must contain adequate amounts of proteins, lipids, carbohydrates, vitamins and minerals. In addition, it is necessary to take into account the need for drinking water. However, the modern diet is often unbalanced, unstructured and is often associated with an increasingly sedentary lifestyle.
Human activities to produce food are carried out through land clearing, tillage and the introduction of new plant and animal species, and their effects depend on the extent and frequency of exploitation. An example is the elimination of native vegetation or the passage of heavy machinery, in order to use these lands to raise farm animals that will eventually produce meat and milk for consumption but at the cost of damaging forests. Reducing the amount of forests and vegetation has severe consequences in terms of climate change and the further increase of torrential rains and floods. So, this is an example where increased production of one type of food produces severe damage to the environment. In addition, the main source of contamination is found in the wastewater from slaughterhouses, which includes feces and urine, blood, lint, laundering and residues of meat and fat from carcasses.
In some cases, population growth has led to intensified land use and increased productivity in areas already prepared for cultivation. In other cases, population growth has not been matched by increases in productivity, leading to an increase in land devoted to food production.
On the other hand, the high consumption of processed foods (candies, cookies, mayonnaise, etc.) is packaged in plastic containers that are highly pollutant. Therefore, moving away from a more natural food, makes us produce more garbage.
It is necessary to find ways to achieve a sustainable balance without giving up the fight against hunger and environmental protection. However, there are currently economic interests that influence the forms of production and the type of food the population eats. And the increase in the world's population means that arable land per inhabitant is constantly decreasing. The environmental impact that natural and human systems can tolerate has its limits.
There are also more and more farmers reducing the use of pesticides and fertilizers, but this production is limited in relation to total food production. There is evidence that these production strategies, in addition to being more environmentally beneficial, are economically viable for the market sectors they serve. However, most large-scale commercial producers find the intensive use of pesticides and mineral fertilizers economically profitable, and there has not been a general acceptance of environmentally friendly production technologies such as integrated pest management and integrated plant nutrition systems.
As a summary, currently the type of food we eat and the way we produce it, damages the environment of our planet. And if this continues, we will reach an irreversible point where we will destroy the only planet we have to live on.

Answer:
The correct answer is - O and 6.9; 7.1 and 14
Explanation:
A measuring scale that tells about the acidity or basicity or alkaline nature of a particular object or solution is possible with the help of a pH scale that measures how acidic or basic a solution or object is.
It ranges between 0 to 14. pH less than 7 or ranging from 0.0 to 6.9 is acidic and more than 7 or from 7.1 to 14.0 is basic or alkaline in nature. A measure of the relative amount of H+ ion and OH- ions in water is pH.

- sunlight
- precipitation
- temperature
- soil
- plants
- animals
- herbivores
- carnivores
- omnivores
- decomposers
*pls help me*
Answer:
Carnivores will feed on herbivores, omnivores, and other carnivores in an ecosystem. A natural community depends on the presence of carnivores to control the populations of other animals. Large carnivores include wolves and mountain lions. A large carnivore might hunt down large herbivores such as elk and deer. Medium-sized carnivores include hawks and snakes, and these animals typically feed on rodents, birds, eggs, frogs, and insects. Examples of small carnivores include some smaller birds and toads. These carnivores may eat insects and worms. Carnivorous animals have strong jaws and sharp teeth to enable them to tear and rip prey. These animals often have long, sharp claws that they also use to tear prey. Carnivores depend on sufficient prey in the food chain to give them the food they need. If the herbivore population or the population of other carnivores declines in an ecosystem, carnivores may not survive.
the importance of glaciers as a force of erosion. Include how glaciers Form, where they form, how they change land, and the landforms they create.
Answer:
Glaciers.
A glacier is a huge mass of ice that moves very slowly downhill along the landscape.
Glaciers form in high latitudes near Earth's poles and at high altitudes, They form due to the accumulation (piling up) and compaction (packing down) of snow.As the glaciers expand, due to their accumulating weight of snow and ice they crush and abrade and scour surfaces such as rocks and bedrock. The resulting erosional landforms include striations, cirques, glacial horns, arêtes, trim lines, U-shaped valleys, roches moutonnées, overdeepenings and hanging valleys.
