Organelles within a cell interact as a system to maintain homeostasis. The destruction of which of the following organelles would cause the MOST damage to the cytoplasm of a cell? А. ribosome b. chloroplast c. cell membrane D. Golgi apparatus
Answer:
cell membrane
Explanation:
cuz
The destruction of the organelle known as cell membrane would cause the
most damage to the cytoplasm of a cell.
The cell membrane is a covering in cells which help to protect the
cytoplasm .The cytoplasm contains most of the organelles such as
lysosomes, ribosomes etc.
The cell membrane also controls the substances which enters and leaves
the cell and destroying it will lead to attack on the cells from other
organisms or a higher concentration which may lead to shrinking and death.

What is the structure inside of the nucleus called and the name of the phase of the
picture below?
a. chromatid and interphase
b. chromosome and prophase
C. chromatin and interphase
d. centromere and mitosis
you haven't added a picture
Explanation:
But if you can describe the picture I can answer it
The nucleus is the major and the central organ of the cell. The structure inside of the nucleus is chromatin and the phase is interphase.
What is chromatin and interphase?Chromatin is a complex structure present only in the eukaryotic cells that are composed of protein and DNA. It is required for the packaging of the long DNA threads into a compact and dense form.
Chromatin makes up the chromosome and is the packaging element of the genetic material. The basic and smallest unit of the chromatin is the nucleosome.
Interphase is one of the cell cycle periods that contain the non-dividing phase. The G1, S and the G2 phase of the cell cycle are part of the interphases.
In this phase, the cell undergoes the process of replication or duplication and cell growth. Not the actual division of the cell occurs instead it prepares the cell for the division.
Therefore, option c. interphase and chromatin are the phases and the structures present inside the nucleus.

using what have you learnt about the effect of concentration gradient and surface area to volume ratio, explain the adaptations of a leaf for photosynthesis
Answer:
thanks
Explanation:
Leaves are adapted for photosynthesis and gaseous exchange.
They are adapted for photosynthesis by having a large surface area, and contain openings, called stomata to allow carbon dioxide into the leaf and oxygen out. Although these design features are good for photosynthesis, they can result in the leaf losing a lot of water. The cells inside the leaf have water on their surface. Some of this water evaporates, and the water vapour can then escape from inside the leaf.
When water evaporates from the leaves, resulting in more water being drawn up from the roots, it is called transpiration.
To reduce water loss the leaf is coated in a waxy cuticle to stop the water vapour escaping through the epidermis. Leaves usually have fewer stomata on their top surface to reduce this water loss.
Leaves enable photosynthesis to occur. Photosynthesis is the process by which leaves absorb light and carbon dioxide to produce glucose (food) for plants to grow. Leaves are adapted to perform their function, eg they have a large surface area to absorb sunlight.
Plants have two different types of 'transport' tissue, xylem and phloem. These specialised tissues move substances in and around the plant.
What are some Non-examples of a Fossil record?
Answer:
Explanation:
A fossil record is a group of fossils which has been analyzed and arranged chronologically and in taxonomic order. Fossils are created when organisms die, are incased in dirt and rock, and are slowly replaced by minerals over time. What is left is a mineral impression of an animal which once existed. Many fields and specialties are utilized to categorize and arrange these fossils, including comparative anatomy, radiometric dating, and DNA analysis. Using the data from the fossil record, scientist try to recreate phylogenies, or trees describing the relationships between animals, both alive and extinct. The fossil record helps inform how different groups of animals are related through evolution.
Answer:
Fossils are the geologically altered remains of a once-living organism and/or its behaviour. There are two main types: body fossils represent all or part of the organism’s body, and trace fossils show evidence of the organism’s behaviour. The study of fossils is called paleontology, from the Greek meaning ‘ancient (paleo-) being (onto-) study (-logy)’. Scientists who study fossils are called paleontologists. Fossils are of particular interest to geologists as they can help determine the age of a particular rock compared to other rocks, or identify the environment in which the rock was formed.

Choose the true statement about prokaryotic and eukaryotic DNA replication. View Available Hint(s) Choose the true statement about prokaryotic and eukaryotic DNA replication. Eukaryotic DNA replication involves less protein factors than does prokaryotic DNA replication. Eukaryotic DNA replication begins at multiple origins of replication, while prokaryotic DNA replication begins at a single origin of replication. Prokaryotic genomes take longer to replicate than eukaryotic genomes. Prokaryotic DNA polymerases replicate DNA 5' to 3', while eukaryotic DNA polymerases replicate DNA 3' to 5'.
Answer:
The correct answer is - Eukaryotic DNA replication begins at multiple origins of replication, while prokaryotic DNA replication begins at a single origin of replication.
Explanation:
There are several differences in the prokaryotic and eukaryotic DNA replication as it takes place in the cytoplasm in prokaryotes whereas it occurs in the nucleus in the eukaryotes. The other difference is that it is a continuous process in prokaryotes but it occurs during the S phase only in eukaryotes.
In prokaryotes, the DNA replication begins at a single origin of replication in both directions and in eukaryotes, DNA replication starts at multiple origins of replication.

Which cell structure plays a direct role in the release of chemicals from the cell?
Answer:
The correct answer is - the cell membrane.
Explanation:
When a human cell gets an external stimulus it triggers the production of the specific compound or chemical release which is packed in vesicles from the endoplasmic reticulum and Golgi apparatus to the cell membrane. The cell membrane is the cell organelle that allows or prohibits the entry or exit of any substance.
Chemical release or secretion also depends on the cell membrane and it allows the secretion of chemicals and plays an important role in the secretion of chemical, hormones, or any substance.
Cell membrane is an structure that plays a direct role in the release of chemicals from the cell.
The cell membrane is the wall that cells have, allowing them to remain independent from the external environment.
The membrane has receptors, which are molecules or sets of molecules, capable of recognizing and responding to signals from the extracellular medium, carrying specific information.
When these signals reach the plasma membrane, internal signals are triggered in the cell, both activating and inhibiting different cellular processes and the release of chemicals.
As an example of these external signals we can cite the release of chemicals such as hormones, for example insulin, which increases the synthesis of glycogen.
Therefore, we can conclude that cell membrane is an structure that plays a direct role in the release of chemicals from the cell.

5 The theory of plate tectonics was, at first, rejected by most scientists. Now most geologists accept that tectonic plates exist and that these tectonic plates can and do move. What is responsible for the change in how scientists think about plate tectonics? A New evidence was discovered that made scientists revise their ideas. B. Tectonic plates have begun to move faster and faster over time. C There are more people studying science now than in the past. D Scientists can now travel underneath the plates and observe their motion.
Tectonic plates have begun to move faster and faster, leading to a change in scientists' thinking about plate tectonics. Hence the correct option is (B).
What is Tectonic Plates?
Tectonic plates are also known as lithospheric plates. It is a massive, irregularly shaped slab of solid rock that is composed of both continental and oceanic lithosphere. The size of the plates varies greatly from a few hundred to thousands of kilometres.
The plates are the largest in the Pacific and Antarctic Oceans. Its thickness also varies greatly, ranging from less than 15 km for young oceanic lithosphere to about 200 km or more for ancient continental lithosphere.
Earth's rigid surface known as the lithosphere acts as a skin that rests and slides over a semi-molten layer of rock called the asthenosphere. It can break into many different plates because of differences in the density of rock and differences in subsurface heating between one region and the next.
Thus, Tectonic plates have begun to move faster and faster, leading to a change in scientists' thinking about plate tectonics. Hence the correct option is (B).

Based on everything you’ve read, which symptoms could indicate an eating disorder that might not be detectable by measuring BMI? What subjective and objective observations could you use to help detect other eating disorders in a clinical setting like the one described in this scenario?
Answer:
Detection requires awareness of risk factors for, and symptoms and signs of, anorexia nervosa (participation in activities valuing thinness, family history of an eating disorder, amenorrhea, lanugo hair) and bulimia nervosa (unsuccessful attempts at weight loss, history of childhood sexual abuse, family history of depression, erosion of tooth enamel from vomiting, parotid gland swelling, and gastroesophageal reflux). Providers must also remain alert for disordered eating in female athletes (the female athlete triad) and disordered eating in diabetics. Treatment requires a multidisciplinary team including a primary care practitioner, nutritionist, and mental health professional. The role of the primary care practitioner is to help determine the need for hospitalization and to manage medical complications (arrhythmias, refeeding syndrome, osteoporosis, and electrolyte abnormalities such as hypokalemia).
